Removal and replacement procedures 58
BBWC battery 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 29).
2. Do one of the following:
• Unlock and remove the bezel ("Front bezel" on page 30).
• Extend the server from the rack (on page 29).
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.
