After installing a battery pack, you might see a POST message during reboot indicating that the array
accelerator (cache) is temporarily disabled. This behavior 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 operates properly while the battery pack is
recharging, although the performance advantage of the array accelerator is absent. When the battery
pack has been charged to a predetermined level, the array accelerator is automatically enabled.
If the battery case is located in a hard drive slot:
1. Back up all data.
2. Close all applications.

4. Remove the server from the enclosure.
5. Remove the server access panel.
6. Remove the battery case from the hard drive slot.
7. Disconnect the battery cable.
8. Invert the battery case.
