Battery-backed write cache battery 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.

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.

To install the BBWC battery option:

1.

Power down the server (on page

2.

Extend the server from the rack, if applicable ("
