To remove the component:
1. Power down the server ("Powering down the server" on page 17
).
2. Extend or remove the server from the rack ("Extending the Server from the
Rack" on page 16
, "Removing the server from the rack" on page 18).
3. Remove the access panel ("Removing the access panel" on page 19
).
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 will be lost if the cable is detached.
