Installing a ServeRAID controller battery on the remote battery tray

The Intelligent Battery Backup Unit (iBBU) is an optional battery for the ServeRAID
adapter. It is referred to as the battery throughout this section. You must install the
battery at a distance from the ServeRAID controller to avoid overheating.
To install a ServeRAID controller battery on the remote battery tray, complete the
following steps:
1. Read the safety information that begins on page v and "Installation guidelines"
on page 28.
2. Turn off the server and peripheral devices, and disconnect the power cords
and all external cables.
3. Remove the server cover (see "Removing the top cover" on page 37).
4. Remove the PCI riser-card assembly (see "Removing the PCI riser-card
assembly" on page 38).
5. If a battery and battery carrier are attached to the ServeRAID controller,
remove the three screws that secure the battery carrier to the ServeRAID
controller. Set the battery and battery carrier aside.

controller:
