Installing a capacitor pack
CAUTION: To prevent a server blade 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 blade 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.
IMPORTANT: The battery pack might have a low charge when installed. In this case, a POST
error message is displayed when the server blade is powered up, indicating that the battery pack
is temporarily disabled. No action is necessary on your part. The internal circuitry automatically
recharges the batteries and enables the battery pack. This process might take up to four hours.
During this time, the cache module functions properly, but without the performance advantage of
the battery pack.
To install the component:
1. Close all applications, and power down the server blade (on page 14). This procedure flushes all data
from the cache.
2. Remove the server blade (on page 15).
3. Remove the access panel (on page 16).
4. Install the cache module ("Installing a cache module" on page 51).
5. Connect the cable to the battery.
