Cache Battery Installation Instructions for HP Smart Array P400 Controllers

NOTE: Your model might look different from the one
illustrated.
NOTE: After installing a battery pack, you might see
a POST message during reboot indicating that the
array accelerator (cache) is temporarily disabled. This
is normal, because the new battery pack is likely to
have a low charge. You do not need to take any
action, because the recharge process begins
automatically when the battery pack is installed. The
controller will operate properly while the battery pack
recharges, although the performance advantage of the
array accelerator will be absent. When the battery
pack has been charged to a satisfactory level, the
array accelerator will automatically be enabled.
Replacing a battery
WARNING: There is a risk of explosion, fire,
or personal injury if the battery pack is not
properly handled. Refer to "Battery
replacement notice (on page 2)" before
installing or removing any item that contains
a battery pack.
1. Close all applications, and then power down the server.
This procedure flushes all data from the cache.
CAUTION: Do not replace a battery pack while the
server is powered up. In this situation, the loose end of
the battery cable that is still connected to the cache
can cause a short circuit, leading to permanent
electrical damage.
2. Disconnect the server from the AC power source.
3. Observe the BBWC Status LED.
• If the LED is blinking every two seconds, data is still
trapped in the cache. Restore system power, then
repeat the previous steps in this procedure.
• If the LED is not lit, proceed with the next step.
4. Unplug the cable from the battery pack.
5. Remove the battery pack from the server.
6. Plug the cable into the new battery pack.
7. Install the new battery pack into the server.
8. Verify that the other end of the cable is properly seated
in the cache connector.
