Turning on the power after an overtemperature shutdown
If your FAStT900 Storage Server shuts down unexpectedly and you received a
″
Maximum temperature exceeded
″
alert from the storage server before it
shutdown, take the following precautions to cool it before you power on the unit:
1. Turn off the power switches to allow the FAStT900 Storage Server to cool.
2. When the room temperature is below the upper operating temperature of 35° C
(95° F), turn on the power switches.
3. Check the FAStT900 Storage Server for faults or damage. Use the
storage-management software to check the overall status of the FAStT900
Storage Server and its components. Correct any problems indicated.
Turning on the power after an emergency shutdown
Use this procedure to regain normal system operation after a power failure or
emergency shutdown:
1. Check all components and cables for damage. If there is no visible damage,
continue with Step 2; otherwise, service the system.
2. Make sure the power cords are plugged in.
3. Make sure that the circuit breaker, drive enclosures, and storage server power
switches are in the off position.
4. Turn on the circuit breakers in the rack cabinet, and turn on the power switches
on all drive enclosures attached to the FAStT900 Storage Server.
Important: You must turn on the drive enclosures before you turn on the
FAStT900 Storage Server. The controllers might not recognize the correct
configuration if the attached drives are powered up after the FAStT900 Storage
Server. For instructions on how to power up the drive enclosures, refer to the
drive enclosure documentation.
5. Turn on both power switches on the back of the FAStT900 Storage Server. For
the location of the power switches, see Figure 23 on page 18.
6. Check the status of the FAStT900 Storage Server and other devices. Make sure
all fault indicator lights are off on the front and back of the FAStT900 Storage
Server. For more information, see “Checking the indicator lights” on page 20.
7. When all the devices are powered up, check the overall system status by using
the storage-management software.
Checking the battery service date
Note: Replace the battery whenever it fails to hold a charge or every three years.
Operating the FAStT900 Storage Server in a hot environment (above 35° C
or 95° F) lowers the battery life expectancy.
To check the battery service date, perform the following steps:
1. Remove the FAStT900 Storage Server bezel, as shown in Figure 21 on
page 16.
