IMPORTANT: When installing or replacing server components, one or more fans might need to
be removed. To prevent an orderly or immediate server shutdown, HP highly recommends
powering down the server during these procedures. To determine if powering down is required,
see the specific procedure.
To remove the component:
1. Power down the server (on page 22).
2. Do one of the following:
o Open or remove the tower bezel, as needed ("Open or remove the tower bezel" on page 22).
o Extend the server from the rack (on page 24).
3. Remove the access panel (on page 25).
4. Remove the fan from the air baffle.
To replace the component, reverse the removal procedure.
Remove the BBWC battery pack or the FBWC

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
