Removal and replacement procedures  32 

  IMPORTANT:  The battery pack might have a low charge when installed. In this case, a POST error 

message is displayed when the server 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.

  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. 

Open the latches, and remove the BBWC cache module. 

 

Disconnect the cable from the cache module. 

To replace the component, reverse the removal procedure.
