Temperature Control
Keeping the unit within the range of normal operating temperatures (see
Appendix A, “Specifications”) is important to the long life and proper function of
the storage system. If the storage system cabinet has been exposed to temperature
extremes, allow two hours for it to stabilize to room temperature and humidity
before switching on the power.
Blank filler panels that cover the SCSI device shelves and the disk module
shelves are installed by the factory. These panels must remain installed for the
product to comply with safety and regulatory requirements, and to provide proper
cooling for the disk modules. If a SCSI device shelf filler panel is lost, you can
order replacements (part number C3310-60017). If a hot-swap storage device
shelf filler panel is lost, you can order replacements (part number 5063-5676).
CAUTION To avoid the hazard of electrical shock and to ensure the cooling
system functions properly, the storage system should not be
operated with the door open.
If “FF” (fan fault) is displayed on the LED panel, the cooling fan has failed.
Shut down the system as quickly as possible. Continued operation of the storage
system with a failed fan could result in loss of data or damage to the storage
system and installed devices.
The LEDs on the disk drive modules indicate the status of the cage. If all the
disk drive module LEDs in a cage are flashing yellow, it indicates a possible over
temperature condition in that cage. If all the drives in a cage are flashing red, it
indicates the temperature in that cage has exceeded the operational temperature
range. Immediately begin shut-down procedures and refer to the
“Troubleshooting” chapter in this manual.
Placement
Do not block the cooling vents. Do not place the storage system closer than 6
inches to a wall to ensure sufficient air flow and cooling.
