• Upgrading the HP Smart Array P400i Controller to support six hard drives (on page 58) • Using a PCI SAS or SATA array controller to support six hard drives (on page 59) • Using a PCI array controller and the HP Smart Array P400i Controller to support six hard drives (on page 61) The Battery-Backed Write Cache Enabler, also called the battery pack, works with the cache module to provide transportable data protection, increase overall controller performance, and maintain any cached data for up to 72 hours. The NiMH batteries in the battery pack are continuously recharged through a trickle-charging process whenever the system power is on. Under normal operating conditions, the battery pack lasts for 3 years before replacement is necessary. 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. Removing an integrated HP Smart Array E200i Controller or an HP Smart Array P400i Controller 1. Power down the server (on page 18). 2. Extend the server from the rack (on page 19). 3. Remove the access panel (on page 20). 4. Remove the air baffle ("Remove and install the air baffle" on page 20). 5. Disconnect all cables from the integrated array controller.

The Battery-Backed Write Cache Enabler, also called the battery pack, works with the cache module to
provide transportable data protection, increase overall controller performance, and maintain any cached
data for up to 72 hours. The NiMH batteries in the battery pack are continuously recharged through a
trickle-charging process whenever the system power is on. Under normal operating conditions, the battery

CAUTION:
To prevent a server malfunction or damage to the equipment, do not add or

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.

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
