3 Push the two latches together to fully seat the module in the system. If the latches have small
tabs on the inside, slide the tabs away from you and then close the tabs.
Note: Keep the packaging and the old controller module. You will need to return the failed
component to Apple when you receive a replacement.
Installing or Replacing a Battery Module
You can obtain optional battery modules to protect data in the Xserve RAID controllers’
cache in the event of a power interruption.
The system’s power supplies charge the battery modules when they are installed in the
system. You can check a battery’s charge when the module is out of the system by pressing
the button on the underside of the module. All four green LEDs light up when the battery
module is fully charged. Do not remove a battery module to check its charge; use the RAID
Admin software for that purpose. (See the document “Using RAID Admin and Disk Utility” on
the CD that came with your system for details.)
If no battery modules are installed in the system, the module compartments have covers that
you must remove to install the battery modules.
Follow these steps to install or replace a battery module.

m To remove the cover, squeeze the latches together and pull off the cover.
m To remove a battery module, squeeze the latches together, place your fingers inside the
handle, and firmly pull the unit out of the system.
Squeeze the two latches on the backup
battery compartment cover inward to
release it and then remove the cover.
