Replacing a Fan Module
Hitachi Unified Storage Hardware Service Guide
Precautions when replacing the Fan Module
Observe the following guidelines when replacing a Fan Module.
• Complete the Fan Module replacement within 10 minutes. Otherwise,
an abnormal rise in temperature can power off the storage system.
• If the ALM LED on the controller is ON while the ALM LED of the Fan
Module is ON, resolve the problem with the controller before resolving
the problem with the Fan Module.
• If the Power Unit and Fan Module fail at the same time, replace the
Power Unit first before resolving the problem with the Fan Module.
• If three fans fail, visit the HDS Support Portal at
.
• If you shut down the storage system and turn off the power supply as
part of a planned shutdown, do not remove three Fan Modules from the
storage system.
• For storage systems that have the Power Saving/Power Saving Plus
option, removing and inserting a Fan Module during drive spin-up might
prevent the Module from recovering fully. If the Fan Module does not
recover, wait for all the drives to spin up, and then remove the Fan
Module from the storage system, wait at least 30 seconds, and reinsert
it.
Replacing the Fan Module on a CBL Controller Box
To replace the Fan Module on a CBL Controller Box:
1. Remove the front bezel (see
Removing and replacing the front bezel on
).
2. Be sure the red ALM LED on the Fan Module is ON. This is the Fan Module
you will remove.
3. Loosen the blue screw securing the Fan Module.
4. Slide the Fan Module forward by sliding the latch upward, and then
remove the Fan Module from the slot.
5. After waiting at least 30 seconds, install a new Fan Module into the slot.
6. Be sure the red ALM LED on the new Fan Module is OFF.
7. Confirm that the fans on the new Fan Module are rotating.
8. On the Controller Box, confirm the status of the following LEDs:
DANGER! Wait at least 30 seconds after removing the fan, as the wings
can continue to rotate for a few seconds after the fan is removed. Keep
fingers away from the fan at all times.
NOTE: If you insert the Fan Module without waiting at least 30 seconds,
the Fan Module might not recover normally. If this occurs, remove the
inserted Fan Module from the storage system, wait at least 30 seconds, and
then re-insert the Fan Module into the storage system.
