Hardware options installation 37
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 removing the battery from the cache module. If the amber LED flashes after
15 seconds, do not remove the battery from the cache module. The cache module is backing
up data, and data is lost if the battery is detached before the LED is extinguished.
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.
NOTE: The data protection and the time limit also apply if a power outage occurs. When
power is restored to the system, an initialization process writes the preserved data to the hard
drives.

1. Power down the server blade (on page 14 ).
2. Remove the server blade (on page 15 ).
3. Remove the access panel (on page 15 ).
