Cache
To enable faster data access from disk storage, the following types of caching are performed:
•
Write-back or write-through caching. The controller writes user data in the cache memory on the
module rather than directly to the drives. Later, when the storage system is either idle or aging — and
continuing to receive new I/ O data — the controller writes the data to the drive array.
•
Read-ahead caching. The controller detects sequential array access, reads ahead into the next
sequence of data, and stores the data in the read-ahead cache. Then, if the next read access is for
cached data, the controller immediately loads the data into the system memory, avoiding the latency of
a disk access.

NOTE: See HP P2000 G3 MSA System SMU Reference Guide for more information about volume cache
options.
Transportable CompactFlash
During a power loss or array controller failure, data stored in cache are saved off to non-volatile memory
(CompactFlash). These data are then written to disk after the issue is corrected. To protect against writing
incomplete data to disk, the image stored on the CompactFlash is verified before committing to disk.
In single-controller configurations, if the controller has failed or does not start, and the Cache Status LED is
on or blinking, the CompactFlash will need to be transported to a replacement controller to recover data
not flushed to disk (See Controller failure in a single-controller configuration on page 51 for more
information).
Controller Module
CompactFlash
CAUTION: To preserve the existing data stored in the CompactFlash, you must transport the
CompactFlash from the failed controller to the replacement controller using a procedure outlined in the HP
Controller Module Replacement Instructions, shipped with the replacement controller. Failure to use this
procedure will result in the loss of data stored in the cache module. The CompactFlash must stay with the
same enclosure. If the CompactFlash is used/ installed in a different enclosure, data loss/ data corruption
will occur.
IMPORTANT: In dual controller configurations featuring one healthy peer controller, there is no need to
transport a failed controller’s cache to a replacement controller because the cache is duplicated between
the controllers.
Super-capacitor pack
To protect RAID controller cache in case of power failure, P2000 G3 MSA System controllers are equipped
with super-capacitor technology, in conjunction with CompactFlash memory, built into each controller
module to provide unlimited cache memory backup time. The super-capacitor pack provides energy for
backing up unwritten data in the write cache to the CompactFlash in the event of a power failure. Unwritten
data in CompactFlash memory are automatically committed to disk media when power is restored. While
the cache is being maintained by the super-capacitor, the Cache Status LED flashes at a rate of 1/ 10
second on and 9/ 10 second off.

Connecting controller and drive enclosures
P2000 G3 MSA System controller enclosures — available in either 24 -drive (2.5”) or 12-drive (3.5”)
chassis — support up to eight enclosures (including the controller enclosure) for storage/ expansion, or a
maximum of 149 disk drives. You can also configure drive enclosures of mixed type, as shown in Table 3
The firmware supports both straight-through and reverse SAS cabling. Reverse cabling allows any drive
enclosure to fail — or be removed — while maintaining access to other enclosures. Fault tolerance and
performance requirements determine whether to optimize the configuration for high availability or high
performance when cabling. P2000 G3 MSA System controller enclosures support both 3Gbps and 6Gbps
internal disk drive speeds, together with 3Gbps and 6Gbps expander link speeds. Controller and
expansion modules are identified by <enclosure-ID><controller-ID>. When connecting multiple
drive enclosures, use reverse cabling to ensure the highest level of fault tolerance.
with a chain of connections cascading down (blue). Controller module 1B is connected to the lower
expansion module (5B) of the last drive enclosure, with connections moving in the opposite (reverse)
direction (green).
NOTE: P2000 G3 MSA System controller enclosures support hot-plug replacement of redundant
controller modules, fans, power supplies, and I/ O modules. Hot-add of drive enclosures is also supported.
Connecting controller and D2700 6Gb drive enclosure
A D2700 6Gb drive enclosure, supporting 6Gb internal disk drive and expander link speeds, can be

NOTE: Additional cabling notes:
•
•
Cables required, if not included, must be separately purchased.
When adding more than two drive enclosures, you may need to purchase additional 1m or 2m cables:
•
•
Spanning 3, 4, or 5 drive enclosures requires 1m cables.
Spanning 6 or 7 drive enclosures requires 2m cables.
•
IMPORTANT: Controller modules within the enclosure must be of the same type. Do not install an HP
P2000 G3 FC MSA System and HP P2000 G3 SAS MSA System controller module in the same chassis.
IMPORTANT: Connecting 3Gb and 6Gb drive enclosures limits performance and should be done only
when upgrading legacy product configurations.

Additional cabling considerations
P2000 G3 MSA System controller enclosures (both LFF and SFF models) support each of the drive
enclosures listed above. However, when cabling supported drive enclosures of mixed type, consider the
following factors regarding components equipped with SAS2.0 and SAS1.1 expanders (labeled in Figure 1
•
•
P2000 G3 MSA System controller enclosures support 6Gb and 3Gb drive enclosures.
To avoid performance limitations in a mixed-type drive enclosure environment, cable 3Gb drive
disk drives in the same enclosure.
•
Performance will be limited if a 3Gb drive enclosure is cabled before a 6Gb drive enclosure — and
cannot be avoided — if reverse cabled. A 6Gb drive enclosure will perform at a 3Gbps data transfer
rate if cabled after a 3Gb drive enclosure.

Figure 10 Cabling connections between dual controllers and drive enclosures of mixed type
The figure above shows a sample fault-tolerant cabling scenario on left, and a straight-through cabling
scenario on right. Both diagrams show drive enclosures of mixed type. Do not mix SAS1.1 and SAS2.0
except when upgrading legacy systems.
In the illustration on the left, note that the D2700 6Gb drive enclosures could alternatively be cabled before
the P2000 6Gb drive enclosures. The illustration at the right shows a D2700 6Gb drive enclosure before a
P2000 6Gb drive enclosure, MSA70 3Gb drive enclosure, and MSA2000 3Gb drive enclosure. Note that
the MSA2000 3Gb drive enclosure is cabled after the other drive enclosures, using straight-through
cabling.
Although 6Gb drive enclosures can be cabled after an MSA70 3Gb drive enclosure, performance of the
6Gb devices will be limited to 3Gb.

Testing enclosure connections
NOTE: Once the enclosures’ power-on sequence succeeds, the storage system is ready to be connected to
Powering on/ powering off
Before powering on the enclosure for the first time:
•
•
Install all disk drives in the enclosure so the controller can identify and configure them at power-up.
Connect the cables and power cords to the enclosures as explained in the installation sheet.
NOTE: P2000 G3 controller enclosures and some P2000 G3 drive enclosures do not have power
switches. They power on when connected to a power source, and they power off when disconnected.
•
Generally, when powering up, make sure to power up the enclosures and associated data host in the
following order:
•
Drive enclosures first
This ensures that disks in the drive enclosure have enough time to completely spin up before being
scanned by the controller modules within the controller enclosure.
While enclosures power up, their LEDs blink. After the LEDs stop blinking — if no LEDs on the front
and back of the enclosure are amber — the power-on sequence is complete, and no faults have
•
•
Controller enclosure next
Depending upon the number and type of disks in the system, it may take several minutes for the
system to become ready.
Data host last (if powered down for maintenance purposes).
TIP: Generally, when powering off, you will reverse the order of steps used for powering on.
Power supply
Many controller and expansion enclosures rely on the power cord for power cycling. Connecting the cord
from the PSU power cord connector to the appropriate power source facilitates power on; whereas
disconnecting the cord from the power source facilitates power off.

4 Connecting hosts
Host system requirements
Data hosts connected to P2000 G3 MSA System arrays must meet the following requirements:
•
Depending on your system configuration, data host operating systems may require that multi-pathing is
supported.
TIP: See the HP MSA System VDS and VSS Hardware Providers Installation Guide and HP MSA
System MPIO DSM Installation Guide to aid in planning and implementing your MPIO DSM
installation.
If fault tolerance is required, then multi-pathing software may be required. Host-based multi-path
software should be used in any configuration where two logical paths between the host and any
storage volume may exist at the same time. This would include most configurations where there are
multiple connections to the host or multiple connections between a switch and the storage.
•
Use Windows Server MPIO DSM with Windows Server 2003. To obtain the MPIO DSM, go to the
Products.
•
Use native Microsoft MPIO DSM support with Windows Server 2008. Use either the Server
Manager or the command-line interface (mpclaim CLI tool) to perform the installation. Refer to the
following web sites for information about using the Windows 2008 native MPIO DSM:
•
Use the HP Multi-path Device Mapper for Linux Software with Linux servers. To download the
appropriate device mapper multi-path enablement kit for your specific enterprise Linux operating
•
To prevent Microsoft Windows 2003 data hosts from displaying the Found New Hardware Wizard
when the storage system is discovered, install the SCSI Enclosure Services driver. Download your
product’s SCSI Enclosure Services (SES) driver package from http:/ / www.hp.com/ go/ msa. Select your
product and go to Related Products.
NOTE: P2000 Family SCSI Enclosure Services driver is required for Microsoft Windows 2003.

5 Connecting to the controller CLI port
Device description
P2000 G3 MSA System controllers feature a new command-line interface (CLI) port used to cable directly
to the controller and initially set IP addresses, or perform other configuration tasks. This port differs from
G1 and G2 controllers. It employs a mini-USB Type B form factor, and requires a new cable and additional
support so that a server or other computer running a Linux or Windows operating system can recognize the
controller enclosure as a connected device. Without this support, the computer might not recognize that a
new device is connected or might not be able to communicate with it. For Linux computers, no new driver
files are needed, but a Linux configuration file must be created or modified.
For Windows computers, a special device driver, gserial.inf, must be downloaded from a CD or HP
website, and installed on the computer that will be cabled directly to the controller’s CLI port.
NOTE: Directly cabling to the CLI port is an out-of-band connection because it communicates outside the
data paths used to transfer information from a computer or network to the controller enclosure.
An in-band connection can also be used to configure a new controller. If used, cabling to the CLI port
might not be necessary. The in-band method uses the MSA Device Discovery utility on the Software
Support/ Documentation CD that is included with your system, and is the best way to discover the
controller’s IP addresses automatically, so that you can use them to log into and manage your controllers
using a web browser for SMU, or telnet for the CLI. See Using the MSA Device Discovery Tool to discover
controller’s IP addresses for instructions about how to use the MSA Device Discovery Tool over your existing
in-band connection to discover controller IP addresses without using the CLI port.
Preparing a Linux computer before cabling to the CLI port
Although Linux operating systems do not require installation of a device driver, certain parameters must be
provided during driver loading to enable recognition of the P2000 G3 MSA System controller enclosures.
To load the Linux device driver with the correct parameters, the following command is required:
modprobe usbserial vendor=0x210c product=0xa4a7 use_acm=1
Optionally, the information can be incorporated into the / etc/ modules.conf file.
Downloading a device driver for Windows computers
A Windows USB device driver download is provided for communicating directly with the controller’s CLI
port using a USB cable to connect the controller enclosure and the computer. If you use the MSA Device
Discovery Tool you may not need the download. However, you can download it and install it for future use.
NOTE: Access the download from your HP MSA products page at http:/ / www.hp.com/ go/ p2000.
Select Models — select your product — select HP Support & Drivers, then select Download drivers and
software.
The USB device driver is also available from the P2000 G3 Software Support/ Documentation CD that
shipped with your product.
Obtaining IP values
Using the MSA Device Discovery Tool to discover controller’s IP addresses
The MSA Device Discovery Tool provides the optimal approach for setting network port IP addresses on
Windows or Linux platforms. For help with configuring your P2000 G3 MSA System products, see the
P2000 G3 Software Support/ Documentation CD that shipped with your product.
1. Locate the P2000 G3 Software Support/ Documentation CD included with your P2000 G3 MSA
System storage device.
HP P2000 G3 SAS MSA System User Guide
41
Download from Www.Somanuals.com. All Manuals Search And Download.
2. Insert the P2000 G3 Software Support/ Documentation CD into the CD drive on a Linux or Windows
computer on the network that is connected to your controller enclosure.
3. Use Autorun or manually start the CD.
The MSA Device Discovery Tool will run.
4. Follow the instructions to discover the IP addresses of the controller or controllers.
Record these IP addresses so that you can specify them whenever you manage the controllers using
SMU or the CLI.
Alternatively, you can set network port IP addresses using CLI on HP-UX, Windows, and Linux platforms.
Setting network port IP addresses using DHCP
1. Look in the DHCP server’s pool of leased addresses for two IP addresses assigned to “HP
StorageWorks MSA Storage.”
2. Use a ping broadcast to try to identify the device through the host’s ARP table.
If you do not have a DHCP server, you will need to ask your system administrator to allocate two IP
addresses, and set them using the CLI during initial configuration (described below).
Setting network port IP addresses using the CLI port and cable
If you did not use the MSA Device Discovery Tool to set network port IP values, set them manually using the
CLI port and cable. If you have not done so already, you need to enable your system for using the CLI port.
NOTE: For Linux systems, see Preparing a Linux computer before cabling to the CLI port on page 41. For
Network ports on controller module A and controller module B are configured with the following default
values:
•
•
•
Management Port IP Address: 10.0.0.2 (controller A), 10.0.0.3 (controller B)
IP Subnet Mask: 255.255.255.0
Gateway IP Address: 10.0.0.1
If the default IP addresses are not compatible with your network, you must set an IP address for each
network port using the CLI embedded in each controller module. The CLI enables you to access the system
using the USB (universal serial bus) communication interface and terminal emulation software. The USB
cable and CLI port support USB version 2.0.
Use the CLI commands described in the steps below to set the IP address for the network port on each
controller module. Once new IP addresses are set, you can change them as needed using SMU. Be sure to
change the IP address via SMU before changing the network configuration.
NOTE: Changing IP settings can cause management hosts to lose access to the storage system.
1. From your network administrator, obtain an IP address, subnet mask, and gateway address for
controller A, and another for controller B.
Record these IP addresses so that you can specify them whenever you manage the controllers using
SMU or the CLI.
2. Use the provided USB cable to connect controller A to a USB port on a host computer. The USB mini 5

On a host computer connected to a controller module’s mini-USB CLI port, incorrect command syntax in a
HyperTerminal session can cause the CLI to hang. To avoid this problem, use correct syntax, use a different
terminal emulator, or connect to the CLI using telnet rather than the mini-USB cable.
Be sure to close the HyperTerminal session before shutting down the controller or restarting its Management
Controller. Otherwise, the host’s CPU cycles may rise unacceptably.

CLI port connection
P2000 G3 MSA System controllers feature a new CLI port employing a mini-USB Type B form factor. If you
encounter problems communicating with the port after cabling your computer to the USB device, you may
need to either download a device driver (Windows), or set appropriate parameters via an operating
Fault isolation methodology
P2000 G3 MSA System controllers provide many ways to isolate faults within the system. This section
presents the basic methodology used to locate faults and the associated FRUs (Field Replaceable Units).
The basic fault isolation steps are:
•
•
•
•
Gather fault information, including using system LEDs.
Determine where in the system the fault is occurring.
Review event logs.
If required, isolate the fault to a data path component or configuration.
Gather fault information
When a fault occurs, it is important to gather as much information as possible. Doing so will help you
determine the correct action needed to remedy the fault.
Begin by reviewing the reported fault. Is the fault related to an internal data path or an external data path?
Is the fault related to a hardware component such as a disk drive module, controller module, or power
supply? By isolating the fault to one of the components within the storage system, you will be able to
determine the necessary action more rapidly.
Determine where the fault is occurring
Once you have an understanding of the reported fault, review the enclosure LEDs. The enclosure LEDs are
designed to alert users of any system faults, and might be what alerted the user to a fault in the first place.
When a fault occurs, the Fault ID status LED on an enclosure’s right ear (see Front panel components on
page 17) illuminates. Check the LEDs on the back of the enclosure to narrow the fault to a FRU, connection,
or both. The LEDs also help you identify the location of a FRU reporting a fault.
Use SMU to verify any faults found while viewing the LEDs. SMU is also a good tool to use in determining
where the fault is occurring if the LEDs cannot be viewed due to the location of the system. SMU provides
you with a visual representation of the system and where the fault is occurring. It can also provide more
detailed information about FRUs, data, and faults.
Review the event logs
The event logs record all system events. It is very important to review the logs, not only to identify the fault,
but also to search for events that might have caused the fault to occur. For example, a host could lose
connectivity to a virtual disk if a user changes channel settings without taking the storage resources
assigned to it into consideration. In addition, the type of fault can help you isolate the problem to
hardware or software.
The Log Collector utility allows customers to gather log information for use during support calls. See the
P2000 G3 Software Support/ Documentation CD that ships with your product for details.
Isolate the fault
Occasionally it might become necessary to isolate a fault. This is particularly true with data paths, due to
the number of components comprising the data path. For example, if a host-side data error occurs, it could
be caused by any of the components in the data path: controller module, cable, or data host.

If the enclosure does not initialize
It may take up to two minutes for the enclosures to initialize. If the enclosure does not initialize:
•
•
•
•
Perform a rescan.
Power cycle the system.
Make sure the power cord is properly connected, and check the power source that it is connected to.
Check the event log for errors.
Correcting enclosure IDs
When installing a system with drive enclosures attached, the enclosure IDs might not agree with the
physical cabling order. This is because the controller might have been previously attached to some of the
same enclosures during factory testing and it attempts to preserve the previous enclosure IDs if possible. To
correct this condition, make sure that both controllers are up, and perform a rescan using SMU or the CLI.
This will reorder the enclosures, but can take up to two minutes for the enclosure IDs to be corrected.
To perform a rescan using the CLI, type the following command:
rescan
To rescan using SMU:
1. Verify that both controllers are operating normally.
2. In the Configuration View panel, right-click the system and select Tools > Rescan Disk Channels.
3. Click Rescan.

Controller failure in a single-controller configuration
Cache memory is flushed to CompactFlash in the case of a controller failure or power loss. During the write
to CompactFlash process, only the components needed to write the cache to the CompactFlash are
powered by the super-capacitor. This process typically takes 60 seconds per 1 Gbyte of cache. After the
cache is copied to CompactFlash, the remaining power left in the super-capacitor is used to refresh the
cache memory. While the cache is being maintained by the super-capacitor, the Cache Status LED flashes
at a rate of 1/ 10 second off and 9/ 10 second on.
IMPORTANT: Transportable cache only applies to single-controller configurations. In dual controller
configurations, there is no need to transport a failed controller’s cache to a replacement controller because
the cache is duplicated between the peer controllers.

To preserve the existing data stored in the CompactFlash, you must transport the CompactFlash from the
failed controller to a replacement controller using a procedure outlined in the HP P2000 G3 MSA System
controller replacement instructions, shipped with the replacement controller. Failure to use this procedure
will result in the loss of data stored in the cache module.
CAUTION: Remove the controller only after the copy process is complete, which is indicated by the

Resolving voltage and temperature warnings
1. Check that all of the fans are working by making sure each power supply’s Voltage/ Fan Fault/ Service
Required LED is off or by using SMU to check for yellow yield icon hardware warnings. (In the
Configuration View panel, right-click the enclosure and select View > Overview.)
2. Make sure that all modules are fully seated in their slots and that their latches are locked.
3. Make sure that no slots are left open for more than two minutes.
If you need to replace a module, leave the old module in place until you have the replacement or use a
blank module to fill the slot. Leaving a slot open negatively affects the airflow and can cause the
enclosure to overheat.
4. Try replacing each power supply one at a time.
5. Replace the controller modules one at a time.
Sensor locations
The storage system monitors conditions at different points within each enclosure to alert you to problems.
Power, cooling fan, temperature, and voltage sensors are located at key points in the enclosure. In each
controller module and expansion module, the enclosure management processor (EMP) monitors the status
of these sensors to perform SCSI enclosure services (SES) functions.
The following sections describe each element and its sensors.
Power supply sensors
Each enclosure has two fully redundant power supplies with load-sharing capabilities. The power supply
sensors described in the following table monitor the voltage, current, temperature, and fans in each power
supply. If the power supply sensors report a voltage that is under or over the threshold, check the input
voltage.

Cooling fan sensors
Each power supply includes two fans. The normal range for fan speed is 4,000 to 6,000 RPM. When a
fan’s speed drops below 4,000 RPM, the EMP considers it a failure and posts an alarm in the storage
system’s event log. The following table lists the description, location, and alarm condition for each fan. If
the fan speed remains under the 4,000 RPM threshold, the internal enclosure temperature may continue to
rise. Replace the power supply reporting the fault.

Temperature sensors
Extreme high and low temperatures can cause significant damage if they go unnoticed. Each controller
module has six temperature sensors. Of these, if the CPU or FPGA (Field Programmable Gate Array)
temperature reaches a shutdown value, the controller module is automatically shut down. Each power
supply has one temperature sensor.
When a temperature fault is reported, it must be remedied as quickly as possible to avoid system damage.
This can be done by warming or cooling the installation location.

Cache Status
Green — Cache is dirty (contains unwritten data) and operation is
normal.
Off — In a working controller, cache is clean (contains no
unwritten data).
Blinking green — A CompactFlash flush or cache self-refresh is in
If the LED is blinking evenly, a cache flush is in progress. When a
controller module loses power and write cache is dirty (contains
data that has not been written to disk), the super-capacitor pack
provides backup power to flush (copy) data from write cache to
CompactFlash memory. When cache flush is complete, the cache
transitions into self-refresh mode.
If the LED is blinking momentarily slowly, the cache is in a
self-refresh mode. In self-refresh mode, if primary power is restored
before the backup power is depleted (3–30 minutes, depending on
various factors), the system boots, finds data preserved in cache,
and writes it to disk. This means the system can be operational
within 30 seconds, and before the typical host I/ O time-out of 60
seconds, at which point system failure would cause host-application
failure. If primary power is restored after the backup power is
depleted, the system boots and restores data to cache from
CompactFlash, which can take about 90 seconds.
The cache flush and self-refresh mechanism is an important data
protection feature; essentially four copies of user data are
preserved: one in each controller’s cache and one in each
controller’s CompactFlash.

Power supply LEDs
Power redundancy is achieved through two independent load-sharing power supplies. In the event of a
power supply failure, or the failure of the power source, the storage system can operate continuously on a
single power supply. Greater redundancy can be achieved by connecting the power supplies to separate
circuits. DC power supplies are equipped with a power switch. AC power supplies may or may not have a
power switch (model shown below has no power switch). Whether a power supply has a power switch is
significant to powering on/ off.

B Environmental requirements and specifications
Safety requirements
Install the system in accordance with the local safety codes and regulations at the facility site. Follow all
cautions and instructions marked on the equipment. Also, refer to the documentation included with your
product’s ship kit.
Site requirements and guidelines
The following sections provide requirements and guidelines that you must address when preparing your site
for the installation.
When selecting an installation site for the system, choose a location not subject to excessive heat, direct
sunlight, dust, or chemical exposure. These conditions greatly reduce the system’s longevity and might void
your warranty.
Site wiring and AC power requirements
The following are required for all installations using AC power supplies:
•
All AC mains and supply conductors to power distribution boxes for the rack-mounted system must be
enclosed in a metal conduit or raceway when specified by local, national, or other applicable
government codes and regulations.
•
•
Ensure that the voltage and frequency of your power source match the voltage and frequency inscribed
on the equipment’s electrical rating label.
To ensure redundancy, provide two separate power sources for the enclosures. These power sources
must be independent of each other, and each must be controlled by a separate circuit breaker at the
power distribution point.
•
The system requires voltages within minimum fluctuation. The customer-supplied facilities’ voltage must
maintain a voltage with not more than ± 5 percent fluctuation. The customer facilities must also provide
suitable surge protection.
•
•
Site wiring must include an earth ground connection to the AC power source. The supply conductors
and power distribution boxes (or equivalent metal enclosure) must be grounded at both ends.
Power circuits and associated circuit breakers must provide sufficient power and overload protection. To
prevent possible damage to the AC power distribution boxes and other components in the rack, use an
external, independent power source that is isolated from large switching loads (such as air conditioning
motors, elevator motors, and factory loads).
Site wiring and DC power requirements
The following are required for all installations using DC power supplies:
•
•
•
All DC mains and supply conductors to power distribution boxes for the rack-mounted system must
comply with local, national, or other applicable government codes and regulations.
Ensure that the voltage of your power source matches the voltage inscribed on the equipment’s
electrical label.
To ensure redundancy, provide two separate power sources for the enclosures. These power sources
must be independent of each other, and each must be controlled by a separate circuit breaker at the
power distribution point.
•
The system requires voltages within minimum fluctuation. The customer-supplied facilities’ voltage must
maintain a voltage within the range specified on the equipment’s electrical rating label. The customer
facilities must also provide suitable surge protection.
•
•
Site wiring must include an earth ground connection to the DC power source. Grounding must comply
with local, national, or other applicable government codes and regulations.
Power circuits and associated circuit breakers must provide sufficient power and overload protection.

Weight and placement guidelines
•
•
The weight of an enclosure depends on the number and type of modules installed.
Ideally, use two people to lift an enclosure. However, one person can safely lift an enclosure if its
weight is reduced by removing the power supply modules and disk drive modules.
•
•
Do not place enclosures in a vertical position. Always install and operate the enclosures in a horizontal
orientation.
When installing enclosures in a rack, make sure that any surfaces over which you might move the rack
can support the weight. To prevent accidents when moving equipment, especially on sloped loading
docks and up ramps to raised floors, ensure you have a sufficient number of helpers. Remove obstacles
such as cables and other objects from the floor.
•
To prevent the rack from tipping, and to minimize personnel injury in the event of a seismic occurrence,
securely anchor the rack to a wall or other rigid structure that is attached to both the floor and to the
ceiling of the room.
Electrical guidelines
•
These enclosures work with single-phase power systems having an earth ground connection. To reduce
the risk of electric shock, do not plug an enclosure into any other type of power system. Contact your
facilities manager or a qualified electrician if you are not sure what type of power is supplied to your
building.
•
•
Enclosures are shipped with a grounding-type (three-wire) power cord. To reduce the risk of electric
shock, always plug the cord into a grounded power outlet.
Do not use household extension cords with the enclosures. Not all power cords have the same current
ratings. Household extension cords do not have overload protection and are not meant for use with
computer systems.
Ventilation requirements
•
Do not block or cover ventilation openings at the front and rear of an enclosure. Never place an
enclosure near a radiator or heating vent. Failure to follow these guidelines can cause overheating and
affect the reliability and warranty of your enclosure.
•
•
Leave a minimum of 6 inches (15 cm) at the front and back of each enclosure to ensure adequate
airflow for cooling. No cooling clearance is required on the sides, top, or bottom of enclosures.
Leave enough space in front and in back of an enclosure to allow access to enclosure components for
servicing. Removing a component requires a clearance of at least 15 inches (37 cm) in front of and
behind the enclosure.
Cabling requirements
•
•
•
Keep power and interface cables clear of foot traffic. Route cables in locations that protect the cables
from damage.
Route interface cables away from motors and other sources of magnetic or radio frequency
interference.
Stay within the cable length limitations.
Management host requirements
A local management host with at least one serial port connection is recommended for the initial installation
and configuration of a controller enclosure. After you configure one or both of the controller modules with
an Internet Protocol (IP) address, you then use a remote management host on an Ethernet network to
configure, manage, and monitor.
66
Environmental requirements and specifications
Download from Www.Somanuals.com. All Manuals Search And Download.
NOTE: Connections to this device must be made with shielded cables – grounded at both ends – with
metallic RFI/ EMI connector hoods, in order to maintain compliance with FCC Rules and Regulations.
Physical requirements
The floor space at the installation site must be strong enough to support the combined weight of the rack,
controller enclosures, drive enclosures (expansion), and any additional equipment. The site also requires
sufficient space for installation, operation, and servicing the enclosures, and sufficient ventilation to allow a
free flow of air to all enclosures.
Table 19 and Table 20 list enclosure dimensions and weights. Weights are based on an enclosure having
a full complement of disk drives, two controller or expansion modules, and two power supplies installed.
“2U12” denotes the LFF enclosure and “2U24” denotes the SFF enclosure. The SFF is further delineated by
the standard-depth 2U24 and the new reduced-depth (short) 2U24.

Site wiring and power requirements
Each enclosure has two power supply modules for redundancy. If full redundancy is required, use a
separate power source for each module. The AC power supply unit in each power supply module is
auto-ranging and is automatically configured to an input voltage range from 88–264 VAC with an input
frequency of 47–63 Hz. The power supply modules meet standard voltage requirements for both U.S. and
international operation. The power supply modules use standard industrial wiring with line-to-neutral or
line-to-line power connections.

Power cord requirements
Each enclosure equipped with AC power supply modules requires two AC power cords that are
appropriate for use in a typical outlet in the destination country. Each power cord connects one of the
power supply modules to an independent, external power source. To ensure power redundancy, connect
the two suitable power cords to two separate circuits; for example, to one commercial circuit and one
uninterruptible power source (UPS).

C Electrostatic discharge
Preventing electrostatic discharge
To prevent damaging the system, be aware of the precautions you need to follow when setting up the
system or handling parts. A discharge of static electricity from a finger or other conductor may damage
system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the
device.
To prevent electrostatic damage:
•
•
•
•
•
Avoid hand contact by transporting and storing products in static-safe containers.
Keep electrostatic-sensitive parts in their containers until they arrive at static-protected workstations.
Place parts in a static-protected area before removing them from their containers.
Avoid touching pins, leads, or circuitry.
Always be properly grounded when touching a static-sensitive component or assembly.
Grounding methods to prevent electrostatic discharge
Several methods are used for grounding. Use one or more of the following methods when handling or
installing electrostatic-sensitive parts:
•
•
Use a wrist strap connected by a ground card to a grounded workstation or computer chassis. Wrist
straps are flexible straps with a minimum of 1 megohm (± 10 percent) resistance in the ground cords.
To provide proper ground, wear the strap snug against the skin.
Use heel straps, toe straps or boot straps at standing workstations. Wear the straps on both feet when
standing on conductive floors or dissipating floor mats.
•
•
Use conductive field service tools.
Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an authorized reseller
install the part.
For more information on static electricity or assistance with product installation, contact an authorized
reseller.
