Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Figure 10. Cooling fan  
Airflow is front to rear with cooling air being drawn across the drives, through the  
fans and pressurizing the rear of the enclosure. The pressurized rear allows the  
PSU to draw the air that it requires; perforations at the rear of the chassis allow  
cooling air to flow over the processor heatsinks, server board and PCI cards.  
The cooling system must be operated with low-pressure rear exhaust installation  
(back pressure created by rack doors and obstacles not to exceed 5 pascals [0.5mm  
Water gauge]).  
The cooling system provides sufficient capacity to ensure that drive maximum  
temperatures have not exceeded at 35°C (95°F) with one failing fan at sea level.  
The cooling cage contains ten individual high-speed single-rotor axial fans,  
individually connected to and interfacing with the enclosure management PCB.  
This interface provides power and speed control to the fans and returns speed  
output from each fan to the management system.  
Drive carrier module  
The drive carrier module consists of a hard disk mounted in a drive carrier. Each  
drive bay can house a single low-profile 2.54-cm (1.0-inch) high, 8.89-cm (3.5-inch)  
form factor SATA disk drive in its drive carrier. The drive carrier has mounting  
locations for SATA drives.  
Each disk drive is enclosed in a sheet steel carrier which provides excellent thermal  
conduction, radio frequency and electro-magnetic induction protection, as well as  
affords the drive with maximum physical protection.  
The front cap of the drive carrier supports an ergonomic handle, which provides  
the following functions:  
v Camming of drive carrier into and out of drive bays.  
v Positive "spring loading" of the drive/backpane connector.

allowing access to the cooling fans. If it becomes necessary to completely  
remove the system, pull the enclosure out until it stops then rotate the  
latches, shown in Figure 15 (right hand up, left hand down), to completely  
remove the enclosure from the rack.  
Power cord connection  
CAUTION:  
The power connection must always be disconnected prior to removal of a PSU  
from the enclosure.  
To connect the power cord, do the following:  
1. Observe all safety and ESD precautions listed in the Safety and Warranty Guide.  
2. Attach a power cord for the installed PSU. The Power On LED (see ꢀ1ꢁ in  
Figure 16) for the PSU will blink green when AC main power is present. The  
Power On LED will illuminate a constant green when power to the PSU is  
turned on.  
Figure 16. Connecting power cords  
Grounding checks  
The SMC - Storage Array must only be connected to a power source that has a  
safety electrical earth connection.

2. Enable the LSI MPT SAS Controller option, which is present in the Mass  
Storage Controller Configuration settings under the Advanced tab.  
3. If you add DIMMS to increase system memory, the default BIOS option limits  
the memory visible to the operating system to 2.50GB. To make more memory  
visible to the operating system, modify the Memory Mapped I/O Start Address  
option, which is present in the PCI Configuration settings under the Advanced  
tab.  
4. To boot from the network using PXE boot, enable the option Onboard NIC  
ROM option, which is also present in the PCI Configuration settings. The  
device boot order registers this change after you save the changes and reboot.  
5. To boot from the boot drive attached to the LSI MPT SAS controller, change the  
hard disk order under the Boot Options tab. Set ID01 LUN0 as the first disk,  
followed by the PCI RAID adapter. If you need to enable the network boot,  
select IBA GE as the first boot device.  
6. To boot from the boot drive attached to the LSI MPT SAS controller, set ID01  
LUN0 as the second boot option under the Boot Options tab.

Chapter 5. Troubleshooting and problem solving  
The Secure Managed Client (SMC) - Storage Array includes an enclosure services  
processor and associated monitoring and control logic to enable it to diagnose  
problems within the enclosure’s power, cooling and drive systems.  
The sensors for power and cooling conditions are housed within the PSUs and  
cooling fans. There is independent monitoring for each unit.  
Initial start-up problems  
The following problems may occur on initial start up:  
Faulty cords  
First check that you have wired up the subsystem correctly. Call your supplier for  
replacement if:  
v Cords are missing or damaged.  
v Plugs are incorrect.  
v Cords are too short.  
Alarm sounds and power up  
Computer doesn't recognize the subsystem  
1. Check that the interface cables from the SMC - Storage Array to the host  
computer are installed correctly.  
2. Check that the LEDs on all installed drive carrier modules are illuminated  
(amber).  
Note: Drive LEDs will not be lit during drive spin up.  
3. Check that drive carrier modules have been correctly installed.  
LEDs  
A green LED is always used for good or positive indication. A flashing  
green/amber LED is used for non-critical conditions. With the exception of the  
drive carrier module LED, which is lit amber under Normal conditions (see “Drive  
carrier module faults” on page 30), a continuous red or amber LED indicates the  
presence of a critical fault within the module.  
Power supply units  
The power supply unit provides a single external bi-color LED to indicate the  
status of the power supply. When AC is applied to the PSU and standby voltages  
are available, the LED will blink green. The LED will be solid on green to indicate  
that all power outputs are available. The LED will be on solid amber to indicate  
that the power supply has failed (shut down due to over current, shut down due  
to over temperature, or a predictive failure).

Thermal cooling  
The Secure Managed Client (SMC) - Storage Array uses extensive thermal  
monitoring to ensure component temperatures are kept low and acoustic noise is  
minimized. Airflow is from front to rear of the enclosure.  
Table 15. Thermal cooling  
Symptom  
Cause  
Action  
If the ambient air is cool  
(below 25°C or 77°F) and the  
fans are observed to increase  
in speed then some restriction  
on airflow may be causing an  
additional internal temperature  
rise.  
The first stage in the thermal  
control process is for the fans  
to automatically increase in  
speed when a thermal threshold  
is reached. This may be caused  
by higher ambient temperatures  
in the local environment and may  
be perfectly normal.  
1. Check the installation for any  
airflow restrictions at either the  
front or rear of the enclosure. A  
minimum gap of 2.5 cm (1 inch)  
at the front and 5 cm (2 inches) at  
the rear is recommended.  
2. Check for restrictions due to dust  
Note: This is not a fault condition.  
build up; clean as appropriate.  
Note: This threshold changes  
according to the number of drives  
and power supplies installed.  
3. Check for excessive re-circulation  
of heated air from rear to front.  
Use in a fully enclosed rack  
installation is not recommended.  
4. Check that all blank modules are  
in place.  
5. Reduce the ambient temperature.

Drive carrier module faults  
Each Drive Carrier module has two LEDs: an upper (green) LED and a lower  
(amber) LED.  
v Under normal operation, the green LED is on and will flicker as the drive  
operates  
v Under normal operation, the amber LED will be:  
– Off if there is no drive present  
– Off as the drive operates  
– On if a drive fault is present  
Dealing with hardware faults  
Ensure that you have obtained a replacement module of the same type before  
removing any faulty module.  
v If the subsystem is powered up and you remove any module, replace it  
immediately. If the subsystem is used with modules or module blanks missing  
for more than a few minutes, the enclosure can overheat, causing power failure  
and data loss. Such use will invalidate the warranty.  
v Replace a faulty drive with a drive of the same type and equal or greater  
capacity.  
v Refer to your vendor-supplied documentation when using storage software for  
handling drive-related hardware faults.  
v All drive bays must be installed with a drive carrier module in order to  
maintain a balanced airflow.  
v All the supplied plug-in power supply units, electronics modules and blank  
modules must be in place for the air to flow correctly around the cabinet

CAUTION:  
Observe all conventional ESD precautions when handling modules and  
components. Avoid contact with backplane components and module connectors,  
etc.  
Note: The top cover of the enclosure covers a service area which should be  
accessed only by qualified service personnel. When the cover is replaced it  
must be secured by turning the lock mechanism to the locked position.  
Continuous operation during replacement  
Depending on how the enclosure system is set up, if a disk unit fails, it can  
normally be replaced without interrupting the use of the system.
