Battery-backed write cache battery pack option
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.
