4.Lift the battery off the cache board (2).
5.Mount the new battery on the cache board by reversing the procedure used in steps 3 and 4.
6.Reinstall the cache board and its battery on the controller by reversing the procedure used in step 2.
IMPORTANT: If the cache is not properly connected, the controller will not boot.
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.
Upgrading the cache
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 35)" 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.
2.Remove the existing cache module:
a. Open the ejector latches on each side of the DIMM connector (1).
