Removal and replacement procedures 33
4.
Remove the cache module.
To replace the component, reverse the removal procedure.
BBWC battery pack or FBWC capacitor pack
CAUTION: To prevent a server malfunction or damage to the equipment, do not add or remove
the battery pack while an array capacity expansion, RAID level migration, or stripe size migration
is in progress.
CAUTION: After the server is powered down, wait 15 seconds and then check the amber LED
before unplugging the cable from the cache module. If the amber LED blinks after 15 seconds, do
not remove the cable from the cache module. The cache module is backing up data, and data is
lost if the cable is detached.
To remove the component:
1. Power down the server (on page 27).
2. Do one of the following:
o Open or remove the tower bezel, as needed ("Tower bezel" on page 30).
o Extend the server from the rack (on page 28).
3. Remove the access panel ("Access panel" on page 31).
4. Disconnect the cable from the cache module only if the battery pack is not being used to recover data
from the server or transfer data to another server.
