Removing the BBWC battery pack
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.
CAUTION:
Do not detach the cable that connects the battery pack to the cache module. Detaching
the cable causes any unsaved data in the cache module to be lost.
