Safety Precautions  
Precautions and Instructions  
Prior to powering on the subsystem, ensure that the correct power range is being  
used.  
The EonStor subsystem comes with 16 drive bays. Leaving any of these drive  
bays empty will greatly affect the efficiency of the airflow within the enclosure,  
viii  
Download from Www.Somanuals.com. All Manuals Search And Download.  
EonStor A16E-G2130-4 Installation and Hardware Reference Manual  
and will consequently lead to the system overheating, which can cause  
irreparable damage.  
If a module fails, leave it in place until you have a replacement unit and you are  
ready to replace it.  
Airflow Consideration: The subsystem requires an airflow clearance, especially  
at the front and rear. The airflow direction is from front to back.  
Handle subsystem modules using the retention screws, eject levers, and the metal  
frames/face plates. Avoid touching PCB boards and connector pins.  
To comply with safety, emission, or thermal requirements, none of the covers or  
replaceable modules should be removed. Make sure that all enclosure modules  
and covers are securely in place during operation.  
Be sure that the rack cabinet into which the subsystem chassis will be installed  
provides sufficient ventilation channels and airflow circulation around the  
subsystem.  
Provide a soft, clean surface to place your subsystem on before working on it.  
Servicing on a rough surface may damage the exterior of the chassis.  
If it is necessary to transport the subsystem, repackage all drives separately.  
Dual-redundant controller models come with two controller modules that must  
be installed into the subsystem. Single controller modules come with a single  
controller module and a metal sheet is placed over the lower controller bay at the  
rear of the subsystem. Since single-controller modules cannot be upgraded, this  
metal sheet should NEVER be removed.  
ESD Precautions  
Observe all conventional anti-ESD methods while handling system  
modules. The use of a grounded wrist strap and an anti-static work pad are  
recommended. Avoid dust and debris in your work area.

Introduction  
1.1 Product Overview  
1.1.1  
Product Introduction  
This chapter briefly introduces the A16E-G2130-4 iSCSI-to-SATA-II  
storage subsystem. The A16E subsystem comes with four (4) GbE host  
ports capable of large I/O transfers over iSCSI packets.  
Infortrend’s iSCSI storage  
supports network initiators  
compatible with the IETF iSCSI  
standard (RFC 3720) with the  
following functionalities:  
Figure 1-1: A16E-G2130-4 Subsystem  
Access control via  
IQN and IP  
CHAP security  
Jumbo frames  
Header Digest mode  
Internet SCSI (iSCSI) protocols are embedded in firmware and I/Os are  
rapidly processed via dedicated algorithms. The iSCSI storage is built  
around reliable hardware and sophisticated RAID technologies. I/O requests  
are packaged and transmitted over local area networks (LANs), wide area  
networks (WANs), or the Internet using the existing networking hardware  
and thus the total cost of ownership is reduced. With the help of the  
networking flexibility, the subsystem is ideal for location-independent data  
storage, backup, and retrieval.  
The subsystem delivers extreme performance that results from the combined  
performance of multiple disk drives and the level of data protection unseen  
in other iSCSI storages. Featuring all standard RAID functionalities as other  
EonStor subsystems, the A16E subsystem provides a reliable platform for  
IT operations such as backup, data-mining, or strategic allocation.  
This subsystem features a high-density architecture that supports up to  
sixteen (16) hot swappable, SATA-II hard drives in a 3U-profile chassis.  
The subsystem is powered by a RAID controller board featuring the latest  
ASIC400, RAID6 ASIC as the XOR engine. The pre-installed 512MB DDR  
RAM DIMM module can be upgraded to a 2GB capacity DIMM to support  
complicated applications that hold numerous ID/LUN combinations.

EonStor A16E-G2130-4 Installation and Hardware Reference Manual  
The controller board is housed in a metal canister and is referred to as the  
“controller module.” The controller module is comprised of a main circuit  
board, an interface faceplate, and a metal canister. The controller module is  
accessed through the rear of the A16E-G2130-4 with the help of ejection  
levers. An optional battery backup unit (BBU) is now equipped with an  
EEPROM that helps record the installation date and notify system  
administrators if the battery’s life expectancy is reached. The BBU is hot  
swappable and is accessed through the controller’s faceplate.  
Four (4) RJ-45 connectors connect the subsystem to network switches or  
Ethernet ports of independent devices. Dual-redundant, hot-swappable  
cooling modules and power supplies protect the subsystem from overheating  
and the down time by power outage. The modular nature of the subsystem  
and the easy accessibility to all major components ensure the ease of the  
subsystem maintenance.  
NOTE:  
On receiving and unpacking your subsystem, please check the package  
contents against the included Unpacking Checklist. If any modules are  
missing, please contact your vendor immediately.

BBU module: An optional BBU module sustains unfinished writes  
cached in memory during a power outage in order to prevent data  
loss. (See Section 1.2.5)  
PSU modules: The hot-swappable PSUs receive single-phase  
power and deliver +5V, +12V, and +3.3V power to the subsystem.  
A power switch is located on each PSU to turn the system on and  
off. (See Section 1.2.6)  
Cooling modules: The redundant cooling modules ventilate the  
subsystem to maintain a cooling airflow across the subsystem. (See  
Section 1.2.7)  
1.1.2.6 Backplane Board  
An internal backplane board separates the front and rear sections of the  
A16E-G2130-4. The PCB board consists of traces for logic level signals and  
low voltage power paths. It contains no user-serviceable components.  
WARNING!  
When inserting a removable module, DO NOT USE EXCESSIVE  
FORCE! Forcing or slamming a module can damage the pins on the  
module connectors either on the module itself or on the backplane. Gently  
push the module until it reaches the end of module slot. Feel the contact  
resistance and use slightly more pressure to ensure the module connectors  
are correctly mated. If the module comes with ejection levers or retention  
screws, use them to secure the module.  
1.2 Subsystem Components  
The A16E-G2130-4 houses many active components and most of them can  
be accessed through either the front or rear panel. The modular design of the  
active components facilitates their easy installation and removal. Hot-swap  
mechanisms are incorporated to eliminate power surges and signal glitches  
that might occur while removing or installing these modules.

Chapter 1: Introduction  
The heart of the A16E-G2130-4 RAID controller subsystem is the iSCSI-to-  
SATA controller board. The controller comes with four (4) GbE Ethernet  
host ports. The subsystem connects to the host through RJ-45 connectors,  
while the connectors are also ready to connect to one or more network  
switches, enabling access to your storage volumes in complex  
configurations such as data-sharing or network zoning.  
The docking connector at the rear of the controller board connects the  
controller module to the backplane board. A DDR RAM DIMM socket is  
strategically placed in an easily accessible location on the controller board  
for easy insertion of the DDR RAM DIMM module.  
1.2.3 Controller Module Interfaces  
All external interfaces that connect to external devices are located on the  
controller module rear panel shown below. The interfaces are listed below.  
Figure 1-7: Controller Module Interfaces – 2-port version  
Host ports: Four (4) Gigabit Ethernet host ports (simulated and  
indicated as CH0 to CH3 in the diagram shown above) connect the  
EonStor subsystem to the networked iSCSI initiators through RJ-45  
connectors.  
COM port: The controller module comes with two (2) COM ports.  
The serial ports are used for local access to the firmware embedded  
configuration utility and the connection to a UPS device.  
LED indicators: Six (6) LED indicators illustrate the system  
statuses for system monitoring. Please see Chapter 3 for more  
information.  
Ejection Levers: Two (2) ejection levers located on the sides of  
the controller ensure that the back-end connectors are properly  
seated in the module slot and properly mated with the backplane.

management interfaces include: telnet, Java-based RAIDWatch  
manager, or the web-based manager invoked by an http console.  
Restore Default LED and button: The push button and LED are  
used to restore firmware defaults in cases when upgrading  
firmware or if an administrator forgets system password. For more  
details, please refer to Chapter 3.  
1.2.4 DIMM Module  
The controller module comes with a preinstalled 512MB capacity or above  
DDR RAM DIMM module and the allocable size can reach 2GB. The  
memory socket is located on the side of the controller board.  
1.2.5 BBU  
PN: IFT-9273CBTE  
An optional, separately purchased Li-ION battery backup unit (BBU)  
module (see the diagram below) can sustain cache memory for days during  
the event of power outage. The battery module comes with an EEPROM  
that marks the installation date, and system administrators will be notified  
when the one-year left expectancy is reached. Please refer to Section 2.6 for  
installation instructions.  
Figure 1-8: BBU Module  
In accordance with international transportation regulations, the BBU module  
is only charged to between 35% and 45% of its total capacity when shipped.  
Therefore, when powering on the subsystem for the first time (see Section  
4.4) the BBU will begin to charge its batteries to their full capacity. It  
normally requires approximately twelve (12) hours for the battery to be fully  
charged. If the battery is not fully charged after twelve (12) hours, there may  
be a problem with the BBU module. You may re-install the battery; and if  
the battery still shows problems with charging, contact your subsystem  
vendor for a replacement. While the battery is being charged, the LED on  
the BBU will start flashing. (See Chapter 3.2.6 for details on the LED  
indicators.)  
You can check battery’s charge level using the RAIDWatch software or the  
embedded firmware utility.

Chapter 1: Introduction  
The subsystem is equipped with two (2) redundant, hot-swappable, 530W  
PSUs, which are installed into the rear section of the chassis. The PSU is  
permanently mounted into a 2U (dual-level) bracket especially designed to  
house both the PSU and a cooling module, which is mounted at the end of  
the 2U bracket.  
NOTE:  
Hot-swapping the PSU also removes the cooling module at the lower  
slot.  
As shown in Figure 1-9, each PSU comes with a power socket and a power  
switch to turn the subsystem on and off. Two (2) embedded cooling fans  
provide sufficient airflow. A single LED indicates the PSU status. When a  
power supply failure occurs, the LED lights red. A rejection handle at the  
rear of the PSU is especially designed to help properly install or remove the  
module.  
A screw hole on the ejection handle helps secure the PSU to the chassis.  
Figure 1-9: PSU Module  
Please refer to Appendix B for the technical information of the PSUs.  
1.2.7 Cooling Modules  
PN: IFT-9273ECFanMod  
Two cooling modules are implemented within the rear sections of PSU  
modules. (see Figure 1-10.) The cooling fans operate at two (2) fan speed  
levels. When the subsystem operates normally, the cooling fans operate at  
the lower speed. If a major component fails or when one of the temperature  
thresholds is violated, the cooling fans automatically raise its rotation speed.  
More technical information can be found in Appendix B.

1.3.3  
Firmware (FW)  
Firmware: The firmware is pre-installed software used to configure the  
subsystem. The latest firmware functionalities include Task Scheduler,  
Intelligent Drive Handling, and Media Scan. Media Scan handles low  
quality drives in both the degraded mode and during the rebuild process.  
Maintenance tasks will then be performed on an entire array or specific hard  
drives. Various options are user-configurable such as priority, start time, and  
execution intervals. For more information, please refer to the Generic  
Operation Manual in the product utility CD.  
1.3.4  
Audible Alarms  
The subsystem comes with an audible alarm that is triggered when a  
component fails or when the pre-configured temperature or voltage  
thresholds are exceeded. Whenever you hear an audible alarm, it is  
imperative that you determine the cause and rectify the problem  
immediately.  
Event notification messages indicate the completion or status of array  
configuration tasks and are always accompanied by two (2) or three (3)  
successive and prolonged beeps.  
WARNING!  
Failing to respond when an audible alarm is heard can lead to permanent  
damage to the subsystem. When an audible alarm is heard, rectify the  
problem as soon as possible.  
1.4 Hot-swappable Components  
1.4.1  
Hot-swap Capabilities  
The subsystem comes with a number of hot-swappable components. A hot-  
swap component is one that can be exchanged while the subsystem is still  
online without affecting the operational integrity of the subsystem. These  
components should only be removed from the subsystem when they are  
being replaced. At no other time should these components be removed from  
the subsystem.

Normalized Airflow  
Proper cooling is referred to as “normalized” airflow. Normalized airflow  
ensures the sufficient cooling within the subsystem and is only attained  
when all components are properly installed. Therefore, a failed component  
should only be removed when a replacement is available. If a failed  
component is removed but not replaced, airflow will disrupted and  
permanent damage to the subsystem can result.

Hardware Installation  
2.1 Introduction  
This chapter gives detailed instructions on how to install the subsystem.  
When installing the subsystem, it is necessary to mount the chassis into a  
rack cabinet and to install hard drives and drive trays. Installation into a rack  
or cabinet should occur before the hard drives or drive trays are installed  
into the subsystem. Please confirm that you received all of the components  
listed on the Unpacking List that came with the subsystem before  
proceeding with the installation process.  
CAUTION!  
Please note that the installation instructions described in this manual  
should be carefully followed to prevent any difficulties and damages to  
your subsystem.  
2.2 Installation Prerequisites  
1. Static-free installation environment: The EonStor A16E-G2130-4  
subsystem must be installed in a static-free environment to minimize  
the possibility of electrostatic discharge (ESD) damage. (See Section  
2.3.2)  
2. Component check: Before installing the EonStor A16E-G2130-4  
subsystem, you should first check to see that you have received all the  
required components. (See Section 2.5) If any items appear damaged,  
contact your vendor for a replacement.  
3. Hard drives: Up to sixteen (16) SATA-I or SATA-II hard drives must  
be purchased separately prior to installing the subsystem. (See Section  
2.8)  
4. Cabling: The EonStor A16E-G2130-4 models all come with one (1)  
audio-jack-to-DB9 cable to facilitate the connection of the COM1 serial  
port of a management computer for terminal emulation management.

STP cables should be applied. Infortrend provides certified cables as an  
optional accessory. One 3-meter STP Ethernet cable is available as an  
accessory option. Please see Chapter 4 for sample topologies and  
configuration options.  
5. Memory module: If you wish to change the pre-installed memory  
module, a separately purchased module can be installed. (See Section  
5.3)  
6. BBU module: If you wish to use a BBU module, the module can be  
purchased separately. For installation instructions, please see Section  
2.7.  
7. Rack installation: The enclosure chassis can be installed into a rack  
cabinet using separately purchased mounting rails, or Infortrend’s IFT-  
9273CSlide32 or IFT-9273Cslide36 slide rails. (See Section 2.10)  
2.3 Safety Precautions  
2.3.1 Precautions and Instructions  
1. Disconnect the power cords if the need should arise for cleaning the  
chassis. Do not use liquid or sprayed detergent for cleaning. Use a  
lightly moistened clothe for cleaning.  
2. Be sure the correct power range (100-120 or 220-240VAC) is supplied  
by your rack cabinet or power outlet. It is highly recommended to  
connect two different power supplies to separate power sources; e.g.,  
one to a power outlet, and the other to a UPS system.  
3. Thermal notice: All drive trays (even if they do not contain a hard  
drive) must be installed into the enclosure. Leaving a drive bay or  
module slot open will severely affect the airflow efficiency within the  
enclosure, and will consequently lead to system overheating. Keep a  
faulty module in place until you have a replacement unit and you are  
ready to replace it.  
4. Rack-mounting: The subsystem is intended to be rack-mounted.  
Following concerns should be heeded when mounting the enclosure  
into a rack cabinet:  
a. An enclosure without disk drives can weigh over 30 kilograms.  
Two (2) people are required to install or relocate the  
subsystem. Drives should be removed from the enclosure  
before moving the subsystem.  
2-2  
Safety Precautions

Chapter 2: Hardware Installation  
b. The subsystem is designed to operate in an environment where  
the ambient temperature around the chassis must not exceed  
40°C.  
c. The openings on the enclosure are for air circulation and hence  
the ventilation openings should never be obstructed.  
d. Proper grounding, over-current protection, and stability  
features should be provided with the rack cabinet into which  
the subsystem is mounted.  
5. Operate the subsystem in an environment with least humidity.  
6. Lay the subsystem on a reliable surface when servicing individual  
modules. A drop or fall can cause injury.  
7. Make sure the voltage of the power source is within the rated values as  
indicated by the label attached to the power supplies before connecting  
the subsystem to the power source. You may also refer to the Appendix  
A of this manual for technical details.  
8. Airflow considerations: The subsystem requires an airflow clearance  
especially on the front and the rear sides. For proper ventilation, a  
minimum of 2.5cm is required between the front of the enclosure and  
rack cover; a minimum of 5cm is required between the enclosure and  
end of the rack cabinet.  
9. Handle the system modules by the retention screws, eject levers, or the  
modules’ metal frames/faceplates only. Avoid touching the PCB boards  
and connector pins.  
10. None of the covers or replaceable modules should be removed in order  
to maintain compliance with safety, emission, or thermal requirements.  
11. If the subsystem is going to be left unused for a long time, disconnect  
the subsystem from mains to avoid damages by transient over-voltage.  
12. Never pour any liquid into ventilation openings; this could cause fire or  
electrical shock.  
13. Never open the subsystem top cover. For safety reasons, only qualified  
service personnel could access the interior of the chassis.  
14. Always secure every enclosure module by its retaining screws or make  
sure it is held in place by its latches or hand screws.  
15. Always make sure the subsystem has a safe electrical earth connection  
via power cords or chassis ground by the rack cabinet.  
16. Be sure that the rack cabinet in which the subsystem chassis is to be  
installed provides sufficient ventilation channels and airflow circulation  
around the subsystem.  
2-3  
Safety Precautions

EonStor A16E-G2130-4 Installation and Hardware Reference Manual  
17. Provide a soft, clean surface to place your enclosure on before working  
on it. Servicing the enclosure on a rough surface may damage the finish  
of the chassis.  
18. If it is necessary to transport the subsystem, repackage all disk drives  
separately.  
19. If one of the following situations arises, get the enclosure checked by  
service personnel:  
a. Any of the power cords or plugs is damaged.  
b. Liquid has penetrated into the subsystem.  
c. The enclosure has been exposed to moisture.  
d. The subsystem does not work well or you cannot get it work  
according to this manual.  
e. The subsystem has dropped and been damaged.  
f. The subsystem shows obvious signs of breakage.  
2.3.2 Static-free Installation  
Static electricity can damage the system’s electronic components. To  
prevent ESD damage to any of the components, follow these precautions  
before touching or handling them:  
Discharge the static electricity accumulated in your body by  
wearing an anti-static wristband.  
Use antistatic strap during handling. Connect the equipment end of  
the strap to an unfinished chassis surface.  
Avoid carpets, plastic, vinyl, and styrofoam in your work area.  
If the need should arise for carrying subsystem modules from one  
place to another, carry them in a static shielding container.  
Avoid the contact between PCBs and clothing.  
Handle all components by holding their edges or metal frames.  
Avoid touching the exposed circuitry on PCB boards and connector  
pins.

EonStor A16E-G2130-4 Installation and Hardware Reference Manual  
2.7.2 BBU Warnings and Precautions  
Install or replace the BBU module only with a BBU module  
supplied by your subsystem vendor. Use of battery cells  
provided by another source will void our warranty.  
Always dispose of discharged or used batteries in an  
ecologically responsible manner. Dispose used BBUs at  
authorized battery disposal sites only.  
Do not use nor leave the BBU near a heat source. Heat can  
melt the insulation and damage other safety features of battery  
cells, possibly leading it to acid leak and result in flames or  
explosion.  
Do not immerse the BBU in water nor allow it to get wet. Its  
protective features can be damaged. Abnormal chemical  
reactions may occur, possibly causing functional defects, acid  
leak, and other hazardous results.  
Do not disassemble or modify the BBU. If disassembled, the  
BBU could leak acid, overheat, emit smoke, burst and/or  
ignite.  
Do not pierce the BBU with a sharp object, strike it with a  
hammer, step on it, or throw it. These actions could damage or  
deform it, internal short-circuiting can occur, possibly causing  
functional defects, acid leak, and other hazardous results.  
If the BBU leaks, gives off a bad odor, generates heat,  
becomes discolored or deformed, or in any way appears  
abnormal during use, recharging or storage, immediately  
remove it from the subsystem and stop using it. If this is  
discovered when you first use the BBU, return it to Infortrend  
or your system vendor.  
2.7.3 Installation Procedure  
To install a BBU into the controller module, please follow these steps:  
Step 1.  
Step 2.  
Prior to installing the BBU module, power off the  
subsystem or restart the subsystem after installation. For  
power off procedures, please refer to Section 4.4.  
Use a screwdriver to loosen the two (2) retention screws  
located on both sides of the dummy plate. (See Figure 2-

2.8 Hard Drive Installation  
2.8.1 Hard Drive Installation Prerequisites  
Hard drives for the EonStor subsystem must be purchased separately. When  
purchasing hard drives, the following factors should be considered:  
Capacity (MB/GB): Use drives with the same capacity. RAID arrays use a  
“least-common-denominator” approach. The maximum capacity of each  
drive used in the array is the maximum capacity of the smallest drive.  
Choose big drives with the same storage capacity.  
Profile: The drive trays and bays of the system are designed for 3.5-inch-  
wide x 1-inch-high hard drives.  
Drive type: The A16E-G2130-4 described in this manual can accommodate  
SATA-I or SATA-II hard drives.  
CAUTION!  
The hard drives and drive trays should only be installed into the  
subsystem after the subsystem has been mounted into a rack cabinet. If  
the hard drives are installed first, the subsystem will be too heavy to  
handle and the possible impact during installation may damage your  
drives.

WARNING!  
1. Handle hard drives with extreme care. Hard drives are very  
delicate. Dropping a drive against a hard surface (even from a short  
distance) and hitting or touching the circuits on the drives with your  
tools may cause damage to the drives.  
2. Observe all ESD prevention methods when installing drives.  
3. Only use screws supplied with the drive canisters. Longer screws  
can damage the hard drives.  
2.8.2 Drive Installation  
Step 1.  
Place the SATA hard drive into the drive tray as shown in  
Figure 2-5, making sure that the hard drive is oriented in  
such a way that the SATA connector is facing the back of  
the drive tray, and the circuit side is facing downward.  
Figure 2-5: Installing a SATA Hard Drive  
Step 2.  
Adjust the drive’s location until the mounting holes in the  
drive canister are aligned with those on the hard drive.  
Secure the drive with four (4) of the supplied 6/32 flat-  
head screws. (See Figure 2-5)  
2.9 Drive Tray Installation  
Once the hard drives have been secured within the drive trays, the drive  
trays can be installed into the subsystem.

WARNING!  
All drive trays must be installed into the enclosure even if they do not  
contain a hard drive. If the trays are not installed into the enclosure, the  
ventilation airflow will not be normalized and the subsystem will overheat.  
Step 1.  
Make sure the rotary bezel lock is in the unlocked  
position, i.e., the groove on its face is in a horizontal  
orientation. If the groove is in a vertical position, as shown  
in Figure 2-6, then the bezel lock is locked and the front  
flap on the drive tray cannot be opened.  
Figure 2-6: Front View of an Individual Drive Tray  
Step 2.  
Open the front flap on the drive tray. (See Figure 2-7)  
Push the release button on the drive tray. The front flap  
will spring open.  
Figure 2-7: Drive Tray Release Button  
Step 3.  
Align the drive tray with the slot in which you wish to  
insert it making sure that it is properly aligned within the  
drive bay. Gently slide it in until the drive tray reach the  
end of drive bay. This should be done smoothly and  
gently. (See Figure 2-8)

Step 4.  
Close the front flap on the drive tray. Make sure the front  
flap is closed properly to ensure that the SATA connector  
at the back of the drive tray is properly mated with the  
corresponding connector on the backplane board. If the  
front flap is not closed properly, the connection between  
the hard drive and the subsystem may come loose and  
mysterious drive signals may result.  
Step 5.  
Lock the flap into place by turning the key-lock until the  
groove on its face is pointing down (vertical orientation).  
(See Figure 2-9)

The subsystem is designed to fit into a variety of 19-inch rack cabinets or  
racks. Make sure you have an appropriate site location and cables prepared  
with adequate lengths to connect to mains and other devices.  
The subsystem should be installed in the rack or cabinet before the hard  
drives and the drive trays are installed. If the drive trays with the associated  
hard drives are installed, the subsystem will be too heavy to mount into a  
rack or cabinet. When installing the subsystem into a rack or cabinet it is  
advisable that two (2) people assist in the mounting process.  
For details on the use of the rackmount rails, please refer to the installation  
instructions that came with them.

Subsystem Monitoring  
3.1 Subsystem Monitoring Overview  
The A16E-G2130-4 subsystem is equipped with a variety of self-monitoring  
features that help to keep subsystem managers informed of the subsystem  
operational statuses. These monitoring features provide vital feedback to  
help you maintain the operational integrity of the subsystem. Prompt  
response to warnings and subsystem component failure notifications will  
ensure data integrity and help ensure the longevity of the subsystem.  
Self-monitoring features include:  
Firmware (FW): The RAID controller in the subsystem is  
managed by preinstalled FW, which can be accessed using a PC  
hyper-terminal connected through the COM1 serial port. Device  
status information can be obtained from the FW-embedded  
configuration utility. The FW is fully described in the Generic  
Operation Manual that came with your system. Please refer to  
this manual for further information.  
RAIDWatch: RAIDWatch is a fully integrated, Java-based,  
Graphical User Interface (GUI) that came with the subsystem and  
can be used to monitor and maintain the subsystem locally or  
remotely over TCP/IP network. Connection to RAIDWatch is  
made using the 10/100BaseT management port.  
The RAIDWatch Panel View can be customized to display a  
graphical representation of the subsystem components in the  
content panel of the RAIDWatch screen. Panel View allows you  
to quickly determine the operational status of critical components.  
Please refer to the RAIDWatch User’s Manual for further details.  
NOTE:  
Detailed installation instructions for RAIDWatch Manager are given in  
the RAIDWatch User’s Manual contained in the CD that came with  
your subsystem.  
Configuration Client: The Configuration Client is a powerful  
module that runs as an independent program from RAIDWatch  
and can be installed redundantly on different hosts. It is used for  
3-1

EonStor A16E-G2130-4 Installation and Hardware Reference Manual  
event notification via email, fax, LAN broadcast, SNMP traps,  
MSN Messenger, SMS (Short Message Service), and the  
configuration utility screen. The Configuration Client helps  
prevent blind time and keeps you constantly informed of the status  
of the subsystem. Instructions on how to activate the  
Configuration Client functionality are given in the RAIDWatch  
User’s Manual.  
LEDs: Device-status-indicating LEDs are located on all important  
modules. These LEDs inform you of the integrity of a given  
component or a host/management link. You should become  
familiar with the various LEDs and be aware of their functions.  
(See Section 3.2)  
Audible alarm: An audible alarm is present on the subsystem  
controller board and will be triggered if any of a number of  
threatening events occurred. These events usually jeopardize the  
functional and operational integrity of the controller board and  
must be heeded at all times. Events such as a breaching of the  
temperature threshold will trigger the alarm. If a subsystem  
manager is present, the manager should use the RS-232 terminal  
console to determine the cause of the alarm and take appropriate  
corrective measures. (See Section 3.3)  
Inter-Integrated Circuit (I2C): The I2C serial bus is used to  
connect various temperature sensors and presence detection  
circuits within the chassis.  
Subsystem monitoring is a necessary part of subsystem management. If  
failure events or other disruptive events are detected and reported, the  
subsystem managers must take appropriate actions to rectify the problem.  
Failure to act in a properly specified manner to a system event (like  
overheating) can cause severe and permanent damage to the subsystem.

drive failure message, you should check the drive tray indicators to find the  
correct location of the failed drive. Replacing the wrong drive can fail two  
members of a logical array (RAID 3/5) and thus destroy data in the array.

Note that restoring default will not affect the  
existing RAID configurations of disk drives.  
Table 3-3: Controller LED Definitions  
Restore NVRAM Defaults – a Push Button  
CAUTION!  
The Restore NVRAM Default push button is a function that carries some  
risks. Firmware restoration will not destroy the existing logical drive  
configurations; however, if the existing logical drives cannot be  
adequately associated with host ID/LUNs after firmware default  
restoration, data loss or inconsistencies might occur.  
There is a non-latch type push button accessed through a round opening  
underneath the Restore Default LED.  
Listed below are the necessary procedures that should be  
completed before using this button:  
1. Before pressing this button to restore firmware defaults, it is highly advised  
to make a list of the existing ID/LUN mapping information. You will need  
the list for restoring ID/LUN mapping after restoring defaults. Default  
restoration will erase the ID/LUN mapping associations (e.g., which logical  
drive is associated with which host ID/LUN), and it is necessary to restore  
the host ID/LUN mapping after firmware default restoration in order to  
access data on the previously configured arrays.  
2. Some of the latest firmware updates may be incompatible with the firmware  
currently running on your subsystem. These updates may require restoring  
firmware defaults before firmware upgrade can actually take place. Before  
using the button, it is highly advised to practice the following:  
Stop host I/Os,  
Backup your data,  
Make a list of host ID/LUN mapping information for future  
references.  
You may also jot down the configured parameters such as the  
performance preferences, specific stripe sizes, etc.  
3. The no. 3 condition that requires restoring defaults is when an administrator  
forgets the password configured to control the access to a RAID subsystem.  
Before pushing this button, also practice the steps listed above. You can  
access array information even without a password.

How to use the button?  
After the subsystem is powered down, you can use a straighten paper-clip to  
press the button. Press and hold down the button, power on the subsystem,  
and wait for the LED to light up to indicate system defaults have already  
been restored.  
3.2.4 Ethernet Port LEDs  
Four (4) GbE host ports, which provide different connection speeds, are  
located on the controller faceplate. Shielded or non-shielded, Cat5e straight-  
through Ethernet cables can be used to connect the RJ-45 ports to the  
network. Two (2) LEDs located on each Ethernet port indicate the Ethernet  
connection speed and link status. See the diagram below for the locations of  
the two (2) LED indicators. Refer to Table 3-5 for the LED definitions.

3.2.5 BBU Module LED  
The BBU module has an LED on its faceplate. (See Figure 3-5) The  
function is the same as the similar LED on the controller module. The LED  
is off when the BBU is functioning normally and is able to sustain the cache  
memory. The LED flashes to indicate the BBU is charging. If the LED is  
illuminating amber, the BBU may have lost its ability to hold electrical  
charge. You should then contact your vendor to verify the problem.  
Figure 3-5: BBU Module LED  
3.2.6 PSU LEDs  
Each PSU comes with a single LED at the back (see Figure 3-6), located  
close to the power switch that turns on the subsystem. This LED indicates  
the operational status of the PSU module. Please refer to the PSU LED  
definitions shown in Table 3-6.

3.2.7 Cooling Module LEDs  
Each individual cooling fan within the cooling module has one (1) red LED  
on the PSU module. The LED corresponds to the single fan in the cooling  
module. (See Figure 3-7) When the LED is on, it indicates the fan has  
failed. When the LED is off, it indicates the fan is functioning properly.  
Figure 3-7: Cooling Module LEDs and Cooling Fan Locations  
The subsystem has a novel approach to stabilizing the temperature within  
the subsystem: When the intelligent sensors on the backplane detect  
elevated temperature, such as high ambient temperature or the failure of any  
cooling or PSU module, the system will turn the cooling fans to high speed  
to extract more heat. Once the ambient temperature cools down to normal or  
the failed modules have been replaced, the cooling fans will return to low  
speed.  
3.3 Audible Alarm  
Different controller environmental and operational parameters (like  
temperature, etc.) have been assigned a range of values between which they  
can fluctuate. If either the upper or lower thresholds are exceeded, an  
audible alarm will automatically be triggered. The alarm will also be  
triggered when an active component on the subsystem fails. If the A16E-  
G2130-4 manager is onsite and hears an alarm, the manager must read the  
error message on the PC terminal or RAIDWatch screen to determine what  
has triggered the alarm. After determining what has occurred, the A16E-  
G2130-4 manager must take appropriate actions to rectify the problem.  
WARNING!  
If an alarm is triggered it is necessary for you to determine the problem.  
If the audible alarm is ignored and the problem is not rectified,  
unexpected damages may occur.

Subsystem Connection and Operation  
4.1 Connection Overview  
4.1.1 Cabling  
Following are the requirements on the type of cables used to connect the subsystem’s  
iSCSI host ports:  
1. Gigabit Ethernet network cables.  
2. Cat5e STP type cables or better performance types (important for meeting the  
requirements imposed by emission standards).  
3. Straight-through Ethernet cables with RJ-45 plugs.  
4. Use of cross-over cables can also automatically be detected and re-routed for a  
valid connection.  
Connection:  
1. Directly to iSCSI initiators or through Gigabit Ethernet switches.  
2. To servers equipped with an iSCSI HBA, and then to client stations with an  
Ethernet NIC or iSCSI HBA.  
3. The subsystem presents its logical capacity volumes through SCSI-like IDs and  
LUN’s. These RAID volumes then appear as iSCSI targets through the  
network.  
NOTE:  
Even though iSCSI initiator software is a cost-effective way of building iSCSI SAN,  
software initiator adds additional workload to the server processor. It is recommended  
to apply iSCSI HBAs that come with TCP/IP offload engines in order to reduce  
overhead.  
4-1

EonStor A16E-G2130-4 Installation and Hardware Reference Manual  
WARNING!  
All cables must be handled with care. Make sure Ethernet cables do not run parallel  
with power cords. To prevent interference within a rack system, the cable routing path  
must be carefully planned and they must not be bent.  
4.1.2 Network Topologies  
The iSCSI host ports connect to Ethernet network devices and iSCSI initiators  
that comply with the IETF iSCSI standard (RFC 3720). Network connection of the  
EonStor A16E subsystem’s iSCSI ports is flexible. The use of network connecting  
devices, subnet, Name Servers, or iSCSI management software can vary from case to  
case. In the following sections, configuration diagrams will be provided to illustrate the  
possible uses of the EonStor A16E subsystem in an iSCSI network.  
Note that these configurations only recommend but do not intend to impose limitations on  
the use of subnet settings or networking paths to servers.  
4.1.3 Points of Failure  
The primary concern for configuring host-side topologies is that points of failure should  
be avoided. It is therefore preferred that the host side be connected to two (2) HBAs and  
better not the onboard Ethernet. Data flow and access management should therefore be  
implemented to avoid access contention. Infortrend’s EonPath  
software can be  
implemented in order to discover a capacity volume through an alternate data link in the  
event of cabling failure.  
4.2 Host Connection Topologies  
4.2.1 Sample Topology – Direct-Attached, Dual-path Connection  
In the configuration shown in Figure 4-1, one (1) EonStor A16E G2130-4 subsystem is  
connected to two (2) servers. These servers are equipped with iSCSI HBAs and using the  
subsystem as the shared storage. Multiple arrays or logical partitions can be created and  
made available separately through different ID/LUN’s on the host ports.  
Note the following with the configuration as diagrammed below:  
4-2  
Host Connection Topologies  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Chapter 4: Subsystem Connection and Operation  
1. The RAIDWatch management software accesses a subsystem through its IP address.  
A management station running RAIDWatch can access the array through the  
10/100BaseT management port.  
2. Configuration of each port connection into a subnet isolates each iSCSI host link,  
decreases overheads, and eliminates the impact of link failure.  
3. Different storage volumes are made available on host ports. Different volumes can  
be separately optimized for different I/O characteristics.

EonStor A16E-G2130-4 Installation and Hardware Reference Manual  
iSCSI Topology and Host LUN Mapping:  
Configuration Details:  
1. A logical drive can be associated with several SCSI IDs on separate channels making  
it a RAID volume accessed through different data paths. The default ID on every  
host channel is ID#0. More can be created if the need arises.  
2. You can manually include or exclude specific iSCSI initiators from the access list to  
you iSCSI arrays. A number of access conditioning factors can be included: IQN,  
NetMask value, CHAP, and IP addresses can be associated with a RAID array (a  
logical drive). In this way, only the authorized host adapters can access your arrays.  
3. In the sample below, 2 logical drives are created each out of 8 member drives.  
Depending on your demands for logical capacity volumes, specific array parameters  
such as optimization modes, spare drives, RAID level, and stripe size/width, can be  
specified when creating logical drives.  
4. Subnet can be created to reduce overheads and provide access security. LAN  
configuration is beyond the scope of this hardware manual.  
5. Multiple arrays or multiple partitions can be created and made available separately  
through different ID/LUN’s on the host ports. The RAID volumes appear as shared  
storage over the Ethernet network.  
6. To ensure the optimal performance, make sure you connect the iSCSI RAID to a  
high speed Gigabit Ethernet network.

servers to see their own power on procedures.  
4.3.3 Power On Enclosure  
To power on the subsystem, turn on the two power switches located on the rear panel of  
the subsystem. (See Figure 4-3) Each switch controls a single PSU, therefore make sure  
that both switches are turned on. There is no limitation on which PSU should be powered  
on first.  
Figure 4-3: Power Switches  
CAUTION!  
Although the PSUs are redundant and a single PSU can provide sufficient power to  
the subsystem, it is advisable to turn both of the power switches on. If only one PSU is  
operating and fails, system operation will be terminated.  
4.3.4 Power On Status Check  
Once the subsystem has been powered on, the status of the entire subsystem should be  
checked to ensure that everything is running smoothly and that there are no complications  
or malfunctions.  
Controller Module LEDs – The controller ready LED should flash green.  
Drive Tray LEDs – The drive status LEDs (that contain hard drives) should all  
lights blue.

Audible Alarm - If any errors occur during the initialization process, the onboard  
alarm will sound in a hastily repeated manner.  
Drive tray LEDs should normally start flashing right after power-on, indicating the RAID  
control unit is attempting to access the hard drives.  
NOTE:  
The subsystem has been designed to run continuously. Even if a component failure  
occurs the fault can be corrected online.  
4.4 Power Off Procedure  
To power down the EonStor subsystem, please follow these steps:  
NOTE:  
When powering down the EonStor subsystem, please ensure that no time-consuming  
processes, like a “Logical Drive Parity Regeneration” or a “Media Scan,” are taking  
place.  
Step 1.  
Step 2.  
Stop I/O access to the system.  
Stop all I/O accesses to the A16E subsystem. Please refer to the related  
documentation of your applications.  
Flush the cache.  
Locate the Cache_Dirty LED on the back of controller module to check  
if there is data cached in the memory. Use the Shutdown Controller  
function to flush all cached data. This prepares the RAID subsystem to  
be safely powered down.  
Step 3.  
Turn off the power.  
Turn off the power. Once the RAID subsystem has been powered down,  
other devices connected to the subsystem can be powered down.

Subsystem Maintenance  
and Upgrading  
5.1. Overview  
5.1.1 Maintenance  
Constant monitoring and maintenance of your A16E-G2130-4 subsystem will minimize  
subsystem downtime and preserve the working integrity of the system for a longer period  
of time. If any of the subsystem components fail, they must be replaced as soon as  
possible.  
WARNING!  
Do not remove a failed component from the subsystem until you have a replacement  
on hand. If you remove a failed component without replacing it, the internal airflow  
will be disrupted and the system will overheat causing damage to the subsystem.  
All of the following components can be replaced in case of failure:  
1. Controller module – Section 5.2  
2. Memory module – Section 5.3  
3. BBU module - Section 5.4  
4. PSU modules – Section 5.5  
5. Cooling fan modules (bundled with PSU modules, not separately available) –  
Section 5.6  
6. Hard drives – Section 5.7  
5.1.2 General Notes on Component Replacement  
With the exception of the RAID controller module, all of the components on the  
A16E-G2130-4 subsystem, including the PSU modules (along with the cooling  
modules within), and drive trays, are hot-swappable and can be replaced while the  
subsystem is still in operation.  
Overview  
5-1

EonStor A16E-G2130-4 Installation and Hardware Reference Manual  
Qualified engineers who are familiar with the A16E-G2130-4 subsystem should be  
the only ones who make component replacements. If you are not familiar with the  
subsystem and/or with RAID subsystem maintenance in general, it is strongly  
advised that you refer subsystem maintenance to a suitably qualified maintenance  
engineer.  
Normalized airflow is directly dependent on the presence of all subsystem  
components. Even if a subsystem component fails, it should not be removed from the  
subsystem until a replacement is readily at hand and can be quickly installed.  
Removing a subsystem component without replacing it can lead to permanent  
subsystem damage.  
When replacing any hot-swappable component, caution should be taken to ensure  
that the components are handled in an appropriate manner. Rough or improper  
handling of components can lead to irreparable damage.  
When removing a RAID controller module from the subsystem, ensure that your  
applications running on servers have been properly closed, users notified of the down  
time, all cached writes conducted, et. Ensure that power has been turned off and that  
all precautionary measures, without exception, are adhered to. The controller board is  
very sensitive and can be easily damaged.  
WARNING!  
When inserting a removable module, take heed that DO NOT USE EXCESSIVE  
FORCE! Forcing or slamming a module can damage the connector pins either on the  
module itself or on the backplane. Gently push the module until it reaches the end of  
module slot. Feel the contact resistance and use slightly more force to ensure the  
module connectors are correctly mated. If the module comes with rejection levers or  
retention screws, use them to secure the module.

Chapter 5: Subsystem Maintenance and Upgrading  
5.2. Replacing Controller Module Components  
5.2.1 Overview  
The controller module consists of the following components:  
DIMM Module  
BBU  
The DIMM module can be replaced when a DIMM module  
fails or if a larger capacity DIMM is required.  
If the BBU has lost its ability to hold electric charge, replace it  
with a certified module. With the new BBU that comes with  
ASIC400 models, an EEPROM is implemented and that  
system administrators will be notified by system events when  
the approximate one-year life expectancy is reached.  
WARNING!  
1. The BBU is hot-swappable and can be independently swapped from the  
controller. However, the BBU is installed into a metal bracket on the  
controller module. When the controller is removed, the BBU is also removed.  
2. It is recommended to remove the BBU before handling the controller because  
once a controller is removed from chassis, BBU will discharge to support the  
cache memory. If you replace a DIMM module with supplied voltage, damage  
may occur.  
5.2.2 Notes on Controller Module Maintenance  
The controller module contains a DIMM module for cache buffer. When replacing the  
controller module, the DIMM module can be removed and used on the replacement  
controller if they are known to be good.  
When replacing the controller module, you must remember that the controller board is  
one of the most sensitive components in the EonStor A16E subsystem. All previously  
stipulated safety precautions (see Chapter 2) must be strictly adhered to. Failure to  
adhere to these precautions can result in permanent damage, resulting in timely delays.  
For your own safety and that of the subsystem, make sure that no power is being  
supplied to the system prior to replacing the controller module.

Step 1. Prepare a clean, static-free work pad or container into which to place  
the controller that will be removed from the chassis.  
Step 2. Make sure there is no data access to the subsystem to avoid losing  
data. Stop all I/O accesses to the subsystem and make sure all cached  
writes have been distributed to disk drives.  
Step 3. Power off the subsystem. If possible, power off the subsystem in the  
way described in Chapter 4. Be sure to flush all cached data before  
powering off the subsystem. If it is not possible to do this turn off  
both PSU modules and disconnect the power cords.  
Step 4. Disconnect all cables that are connected to the controller module you  
wish to replace. These include the Ethernet cables connected to the  
network, and any cable connected to the RS-232C audio jack  
connector.  
Step 5. Remove the BBU module if one has been installed. Loosen the BBU  
module’s retention screws and then retrieve it from the chassis.

5.2.4 Replacing the Controller Module  
If the controller module has failed, replace a failed controller with a replacement from  
your vendor:  
Step 1. Remove the failed controller. (See Section 5.2.3) If the DIMM  
module is undamaged it can be removed (See Section 5.3) and reused  
on the new controller module.  
Step 2. Install a DIMM module on the new controller module. (See Section  
5.3)  
Step 3. Insert the controller module. Align the controller module with the  
controller module bay at the rear of the subsystem, making sure that  
the levers are down. Gently slide the controller module in.  
Step 4. Secure the connection. Once the controller reaches the end and you  
feel the contact resistance, you can life up the levers on the sides. The  
levers will ensure that the back-end connectors are properly mated.  
Step 5. Fasten the hand screws. Once fully inserted secure the controller  
module to the chassis by fastening the retention screws through the  
holes underneath the ejection lever.  
Step 6. Re-attach all the cables that your previously removed. These include  
the cables that connect to the local network or iSCSI initiators that  
were previously attached to the iSCSI ports, and any cable that was  
attached to the RS-232C audio jack connector.  
Step 7. Power up the subsystem.  
5.3. Replacing or Upgrading Memory Modules  
5.3.1 Memory Module Installation Overview  
The subsystem comes with a pre-installed 512MB (or above) DDR RAM DIMM  
module. The controller supports a memory module up to 2GB in size. If DDR  
RAM DIMM modules with a different size need to be used or the original  
memory module is damaged in some way, the pre-installed module can be

Chapter 5: Subsystem Maintenance and Upgrading  
removed and a replacement installed. Replacement and installation instructions  
are described fully below.  
A DIMM socket is located on the controller main circuit board. The controller  
board is a sensitive component and must be treated with care.  
WARNING!  
The controller board in the controller module is a sensitive item. Please ensure that all  
anti-static precautions stipulated above are strictly adhered to. Only qualified  
engineers should replace the DIMM module.  
5.3.2 Selecting the Memory Modules  
If the memory module on the A16E-G2130-4 controller module is going to be replaced,  
the following factors must be considered when purchasing replacement DIMM modules:  
Purchasing a DIMM module: To avoid the compatibility issues, it is  
recommended to contact Infortrend or your subsystem vendor for an updated list  
of compatible DIMM modules. We provide tested modules from reliable  
vendors with reliable chips.  
DDR RAM DIMM modules supported: The subsystem supports 184-pin,  
registered, ECC-capable DDR RAM DIMM modules with memory capacities  
ranging from 512MB to 2GB.  
Installation considerations: When installing the DIMM module, it is necessary  
to remove the controller module. The controller board is more susceptible to  
damage than other components and must therefore be handled with extreme  
care. ALL anti-static precautions specified in Section 2.3 must be strictly  
adhered to.  
Secure installation: When replacing the DIMM module, make sure that the new  
DIMM module is firmly in place prior to installing the controller module. If the  
DIMM module is not firmly in place, the subsystem will not run and the  
controller will need to be removed and the DIMM module correctly installed.  
5.3.3  
DIMM Module Installation  
WARNING!  
The pre-installed modules must be removed prior to installing new modules. Do this  
with care. Sensitive components can be damaged during the process.

Step 1. Prepare an anti-static work pad or container for placing a removed  
module. Use of an ESD grounding strap is highly recommended.  
Step 2. Remove the BBU module, if installed. Carefully place the module for  
it contains Li-ion batteries. Do not drop it to the floor or place it near  
any heat source or fire.  
Step 3. Remove the controller module. See Section 5.2.3.  
Step 4. Remove the previously installed DIMM module from the DIMM  
socket. To do this, push the white module clips on either side of the  
DIMM socket down. By doing this, the previously installed modules  
will be ejected from the DIMM socket. (See Figure 5-4)  
Figure 5-4: Removing a DIMM Module  
Step 5. Gently pull the DIMM module out of the DIMM socket.  
Step 6. Insert the replacement module into the DIMM socket. Make sure the  
white clips of the DIMM socket are in the open positions. Align the  
DIMM module with the DIMM socket by checking its “keyed”  
position. Once aligned, gently and firmly push the DIMM module into  
the socket. The white clips on the sides of the socket will close  
automatically and secure the DIMM module into the socket.

Chapter 5: Subsystem Maintenance and Upgrading  
Step 7. Reinstall the controller module. After the DIMM module has been  
properly installed, install the RAID controller. To do this, align the  
controller module with the controller module bay. Then gently push  
the controller module in the controller bay. Carefully push the  
controller until you feel the contact when the board edge connectors  
are being mated to the backplane. Do not use force. If unusual contact  
resistance is felt, try it again. Use the ejection levers on the sides of  
the controller to secure it into the chassis.  
When the controller is inserted with the lever at its the lowest position,  
notches on the levers should properly clinch to the round metal  
protrusions on the interior walls of module bay. You may then pull the  
lever upward to secure the controller into module bay.  
Step 8. Next secure the controller module into the subsystem by fastening the  
screws through holes underneath each ejection lever.  
5.4. Replacing a Faulty BBU  
The BBU is an optional item for the subsystem that can sustain cache memory in the  
event of a power failure or in the unlikely event of failing both PSUs. The BBU provides  
additional data security and helps minimize the chance of losing data due to power  
outages.  
A BBU consists of a metal bracket, battery cell pack, and a PCB board that connects to  
the controller module. Each BBU is secured to the subsystem using retention screws.  
Please read the BBU handling precautions below before proceeding with the replacement  
procedure.  
Fault Conditions:  
A BBU failure can result from the following:  
1. A BBU has lost its ability to hold electrical charge. This may be the case after the  
battery cells have been recharged for many times regardless of how long the module  
has been used. Therefore, a stable power source is important for system operation.  
2. The charger circuitry implemented with the controller has failed.  
There are other conditions that might trigger the BBU fault events and trigger the BBU  
fault LED:  
1. The temperature sensor embedded with the subsystem’s charger circuit reports a  
temperature reading exceeding the preset threshold. The charger circuits will enter a  
low-power and self-protection state.

EonStor A16E-G2130-4 Installation and Hardware Reference Manual  
2. A BBU module has been charged for over twelve (12) hours. A timer is embedded  
with the charger. When this occurs, the charger will enter a timer fault state. The  
fault condition usually occurs with a brand new BBU or with a totally discharged  
BBU. Charging will resume automatically if you remove and re-install the BBU  
module.  
5.4.1 BBU Warnings and Precautions  
Install or replace the BBU with BBUs supplied by your EonStor vendors only.  
Use of battery cells provided otherwise will void our warranty.  
Always dispose of a replaced battery in an ecologically responsible manner.  
Dispose of used BBUs at authorized battery disposal sites only.  
Do not use nor leave the BBU near a heat source. Heat can melt the insulation  
and damage other safety features of battery cells, possibly will cause acid leak  
and result in flames or explosion.  
Do not immerse the BBU in water nor allow it to get wet. Its protective features  
can be damaged. Abnormal chemical reactions may occur, possibly cause  
functional defects, acid leak, and other hazardous results.  
Do not disassemble or modify the BBU. If disassembled, the BBU could leak  
acid, overheat, emit smoke, burst and/or ignite.  
Do not pierce the BBU with a sharp object, strike it with a hammer, step on it, or  
throw it. These actions could damage or deform it and internal short-circuiting  
can occur, possibly cause functional defects, acid leak, and other hazardous  
results.  
If a BBU leaks, gives off a bad odor, generates heat, becomes discolored or  
deformed, or in any way appears abnormal during use, recharging or storage,  
immediately remove it from the subsystem and stop using it. If this is discovered  
when you first use the BBU, return it to Infortrend or your subsystem vendor.

5.4.2 Replacing a Faulty BBU  
To replace the BBU, please follow these steps:  
Step 1. Remove the faulty BBU from the chassis. The BBU module is  
secured to the chassis with two (2) screws. Loosen the retention  
screws located at the sides of the BBU faceplate, then pull out the  
BBU. (See Figure 5-5)  
Figure 5-5: Remove the Retention Screws from BBU Faceplate  
Figure 5-6 Remove the BBU Module  
Step 2. Install the replacement BBU. After the faulty BBU has been  
removed, the new BBU module can be installed. To do this, align the  
BBU module with the empty slot, and then gently push the BBU  
module into the slot. (See Figure 5-7)

Figure 5-7: Install the BBU Module  
Step 3. Secure the BBU module to the enclosure. Tighten the two (2)  
retention screws as shown above using a Phillips screwdriver.  
Step 4. Reset the subsystem. Find appropriate time to reset the subsystem for  
the subsystem firmware to recognize the replacement module. After  
reset, the BBU LED will start flashing to indicate that the BBU is  
being charged. When the BBU is fully charged, the LED will be off.  
NOTE:  
1. A new or replacement BBU takes approximately seven (7) hours to charge to  
its full capacity. Reset the subsystem whenever a BBU is replaced or added in  
order for the replacement module to take effect.  
2. The life expectancy of a BBU is more than one year. However, it is  
considered a safe procedure to replace the BBU every year. Follow the  
procedures above to replace a used BBU with a replacement in order to  
maintain the fault tolerance feature.  
3. The chance of BBU charger failure is comparatively low. If the cause of a  
failure cannot be determined even after a BBU module is replaced, contact  
your system vendor for a replacement controller and return the controller  
module through Infortrend’s standard RMA procedure.

5.5. Replacing a Failed PSU Module  
5.5.1 Notes on PSU Module Maintenance  
Two (1+1) redundant PSU modules: The subsystem comes with two fully  
redundant, hot-swappable PSU modules. These modules are located at the rear  
section of the subsystem.  
PSU canister: Each PSU module is housed in a robust steel canister, with the  
power supply converter unit in the front and two serial-aligned cooling fans in  
the rear section. When the PSU is removed from the chassis, the cooling module  
is also removed.  
Printed text on PSU handle: Before you insert a new PSU, make sure that the  
printed text on the PSU handle matches the printed text on a partner PSU.  
Double-check to avoid using a PSU of a different EonStor series.  
Figure 5-8: Printed Text on PSU Handle  
Immediate replacement: When a PSU fails, it should ideally be replaced  
immediately. Do not remove the PSU module unless a replacement is readily  
available. Removing a PSU without a replacement will cause severe disruptions  
to the internal airflow and the subsystem will overheat, possibly causing  
irreparable damage to some of the subsystem components.  
WARNING!  
Although the subsystem can operate using a single PSU module, it is not advisable  
to run the EonStor subsystem with a single PSU module for an extended period of  
time.

WARNING!  
1. When a PSU is removed form the chassis, the cooling module is also removed  
from the chassis.  
2. It is recommended that the replacement procedure is completed in less than  
five (5) minutes to prevent the subsystem from overheating.  
Step 5. Install the replacement module. Make sure the ejection handle is at  
its up-most position so that the saddle notches on the sides of the  
handle can snap onto the metal protrusions along the interior walls of  
the PSU slot. Push the PSU into chassis, and when you feel the  
contact resistance, push the handle downward to secure the module.  
Step 6. Secure the PSU to the subsystem by fastening the retention screw  
through the PSU ejection handle.  
Step 7. Replace and Connect the power cord that connects the PSU module  
to the mains.  
Step 8. Power on the PSU module.  
5.6. Cooling Module Maintenance  
5.6.1 Notes on Cooling Module Maintenance  
Redundant cooling modules: The subsystem is equipped with four (4) cooling  
fans, two (2) within each PSU module. These cooling modules control the  
internal operating temperature of the subsystem and therefore their working  
integrity should be maintained at all times.  
Although the cooling modules are fully redundant, it is not advisable to run the  
EonStor subsystem with fans in a single PSU module for an extended period of  
time. If the cooling fans in the only remaining PSU module fail, the subsystem  
will quickly overheat.  
Detecting a failed cooling module: If a cooling module fails, the LEDs located  
at the back of the PSU module, an audible alarm, the firmware, the RAIDWatch  
manager software, or the Configuration Client can notify you.

Chapter 5: Subsystem Maintenance and Upgrading  
Replacing a cooling module: Once you are notified that a cooling module has  
failed, it should be replaced as soon as possible. A failed cooling module should  
only be removed from the subsystem when you have a replacement module  
immediately available.  
5.6.2  
Replacing a Cooling Module  
If one of the cooling modules fails, it must be replaced as soon as possible. The  
cooling module is secured to the PSU module with the six (6) screws from the top. To  
replace the cooling module, follow the steps below:  
WARNING!  
The fan replacement process should be completed within five (5) minutes. If the  
process takes too long, the accumulated heat can damage the subsystem.  
Step 1.  
Step 2.  
To remove the cooling module, remove the PSU module first.  
Please follow the PSU removal process listed in the previous  
discussion.  
Use a medium-size Phillips screwdriver to remove the six screws  
from the top of the PSU module. (See Figure 5-12: Removing a

5.7. Replacing a Failed Hard Drive  
5.7.1  
Hard Drive Maintenance Overview  
Hot-swappable drive trays: The drive trays are all hot-swappable. A disk drive  
failure can be corrected online.  
Handles: If the failed hard drive is behind either the left or right front handle,  
unfold the handles to open the front access to the drive trays.  
Figure 5--14: Open the Front Handles  
Step 1.  
Step 2.  
Open flap: Once the front flap on the drive tray has been opened, the  
drive tray must be removed from the subsystem. Failure to remove  
the drive tray from the subsystem after the front flap has been  
opened may cause data errors.  
Slowly remove a faulty drive: When removing a drive tray from the  
subsystem, pull the drive tray out only about one inch and

EonStor A16E-G2130-4 Installation and Hardware Reference Manual  
then wait for at least 30 seconds for the hard drive motor  
to spin down before taking it out completely. Any impact to  
the hard drive while the drive motor is spinning can damage the hard  
drive.  
There are situations that healthy drives can be removed. In  
operations such as Copying & Replacing member drives with drives  
of larger capacity, you may need the replaced disk drives in other  
installations.  
Step 3.  
Keep a replacement on hand: If a hard drive has failed, make sure  
you have a replacement drive readily available before removing the  
failed drive from the subsystem. Do not leave the drive tray slot  
open for an extended period of time or the normalized airflow will

5.7.2  
Replacing a Hard Drive  
To replace a hard drive, please follow these steps:  
WARNING!  
Hard drives are fragile; therefore, always handle them with extreme care.  
Do not drop the hard drive.  
Always be slow, gentle, and careful when handling a hard drive.  
Handle a hard drive only by the edges of its metal cover, and avoid touching  
its circuits part and interface connectors.  
Step 1.  
Step 2.  
Identify the location of the drive tray that contains a hard drive  
indicated as faulty. You may use firmware utility or RAIDWatch  
software to locate a faulty drive. The drive tray LED should also  
light red.  
Make sure the rotary bezel lock is in the unlocked position, i.e.,  
the groove on its face is in a horizontal orientation. If the groove is  
in a vertical position, as shown below, then the bezel lock is  
locked and the front flap on the drive tray cannot be opened.

Step 3. Open the front flap on the drive tray. Push the release button on the  
front of the drive tray. The front flap will automatically swings up into  
position.  
Figure 5-16: Opening the Drive Tray Front Flap  
Step 4. Remove the drive tray by pulling it one inch away from the drive  
bay. Wait for at least 30 seconds for the disk drive to spin down (if  
the disk drive is removed for a different purpose, e.g., cloning the  
members of a logical drive or Copy & Replace), and then gently and  
carefully withdraw the drive tray from the chassis.

Appendix D  
Uninterruptible Power Supply  
D.1 Uninterruptible Power Supply Overview  
An uninterruptible power supply (UPS) is a separately purchased battery  
backup unit that is connected to an Infortrend subsystem. If the UPS is  
sufficiently large, it should allow the whole subsystem to safely finish the  
ongoing I/Os in the event of an AC power failure.  
D.2 Compatible UPS Supplies  
The APC SMART-UPS 700VA is compatible with the EonStor subsystem.  
D.3 Serial Communication Cable  
Part Number: IFT-9270CUPSCab  
The subsystem is shipped with a customized audio-jack to DB9 serial  
communication cable. The cable is used to connect the controller module on  
a subsystem to a PC hyperterminal for subsystem management. If you wish  
to use a UPS with your subsystem, an additional audio-jack to DB9 serial  
communication cable (see Figure D-1) must be purchased.  
Figure D-1: Audio-Jack to DB9 Serial Communication Cable  
CAUTION!  
The pinouts on the COM2 audio-jack to DB9 serial cable used to connect  
to the UPS are different from the pinouts on the serial cable that was  
shipped with the subsystem. When connecting the UPS device, please  
make sure you use the correct cable type. The cable pinouts are listed in  
Appendix C.  
D-1

EonStor A16E-G2130-4 Installation and Hardware Reference Manual  
D.4 Connecting the UPS to the Subsystem  
D.4.1 Connect the PSU Module Power Cords  
The two (2) power cables shipped with the subsystem must be plugged into  
the power cord sockets in the rear of the PSU modules. The plug at the other  
end of the power cable must be inserted into a socket on the UPS. (See  
Figure D-2) Please refer to the UPS manual to determine the location of  
these sockets. The UPS must then be connected to main power.  
D.4.2 Set the Baud Rate  
The default baud rate for the COM 2 serial port is 38400 and must be  
changed to 2400. For instructions on changing the baud rate, please refer to  
the SCSI to SATA RAID Subsystem’s Operation Manual that came with  
the subsystem.  
D.4.3 Connect COM2  
The separately purchased audio-jack to DB9 serial cable connects the  
COM2 port on the controller module to the UPS directly. (See Figure D-2)  
The cable transmits UPS status updates to the controller module and will in  
turn determine the write policy of the controller module. To connect the  
serial communication cable to the subsystem controller, insert the audio jack  
connector on one end of the cable into the COM2 port on the controller  
module. To see how to connect the DB9 connector to the UPS, please refer  
to the documentation that came with your UPS.

Appendix D: Uninterruptible Power Supply  
D.5 Power On  
When powering on the subsystem, the UPS must be powered on before the  
subsystem. For instruction on how to power on the UPS, please refer to the  
documentation that came with your UPS. Note that the power on sequence  
described in Chapter 4 will be altered. The power on sequence when a UPS  
is connected is shown below:  
Step 1. Power on SCSI channel connection devices (including hubs and  
switches).  
Step 2. Power on the UPS.  
Step 3. Power on the subsystem.  
Step 4. Power on the host computers.  
Step 5. Trigger the firmware to allow the subsystem to detect the UPS.  
To see how to do this please, refer to the Generic Operation  
Manual that came with the subsystem.  
NOTE:  
A UPS can be connected to the subsystem after the subsystem has  
been powered on, but you will have to trigger the firmware to allow  
the subsystem to detect the UPS.  
If you are daisy chaining systems together, be sure to make all the  
cable connections and then power on the A24F-G2224 subsystem that  
is not directly connected to host computer before powering on the  
first subsystem.  
D.6 UPS Status Monitoring  
If a UPS has been correctly connected to the subsystem, the status of the  
UPS will be constantly monitored by the controller through the COM2  
(audio jack) serial port. The status of the UPS will determine the controller’s  
write policy, and messages that appear on the LCD panel and other  
monitoring devices will keep you informed of the UPS status.  
D.6.1 Normal Operational Status  
If the UPS has been connected to main power and the UPS battery power  
level is above 50%, then no status messages will appear and the default  
“Write Back” write policy will be implemented by the controller.

D.6.2 UPS Messages  
The following messages may appear on the LCD screen:  
Message 1: UPS connection is absent”  
This message appears when COM2 has not been connected to the UPS.  
Message 2: UPS connection detected”  
This message appears when the COM2 ports on the subsystem have been  
connected to the UPS.  
Message 3: Warning: UPS AC Power-Loss detected”  
This message appears when the UPS battery power level remains above  
50% but its connection to the AC power supply has been disrupted in some  
way. The write policy changes from write back to write through.  
Message 4: Warning: UPS Battery Low 50%. Please shut down to protect  
data loss”  
This message appears when the UPS battery power level has dipped below  
50% of its capacity and the UPS has either been disconnected from the AC  
power supply or the AC power supply has been disrupted. The write policy  
will be changed from the default write back to write through. If this message  
appears, the subsystem should be properly shut down to avoid data loss.  
Message 5: Warning: UPS Battery Low 50%”  
This message appears when the UPS battery power level has dipped below  
50% of its capacity. The default write policy will be changed from the  
default write back to write through.  
Message 6: UPS Battery restored to safe level”  
This message appears when the UPS battery power level has been restored  
to above 50% of its capacity. The write policy will be changed from write  
through to write back.  
Message 7: UPS AC Power Restored”  
This message appears when the AC power supply to the UPS has been  
reconnected. If the UPS battery power level is below 50%, the write policy  
will remain as write through. If the battery power level is above 50%, the  
write policy will change from write through to write back.
