BBU Replacement Overview

The BBU can sustain cache memory in the event of a power failure
or in the unlikely event of failing both PSUs. The BBU provides
additional data security and helps minimize the chance of losing data
due to power outages.
A BBU consists of a metal bracket, battery cell pack, and a PCB
board that connects to the controller module. Each BBU is secured
to the subsystem using retention screws. Please read the BBU
handling precautions below before proceeding with the replacement
procedure.

Insert the replacement module into the DIMM
socket. Make sure the white clips of the DIMM socket
are in the open positions. Align the DIMM module with
the DIMM socket by checking its "keyed" position.
Once aligned, gently and firmly push the DIMM
module into the socket. The white clips on the sides of
the socket will close automatically and secure the
DIMM module into the socket.
Reinstall the controller module (See Section 5.2.3.1,
Step 5-8 or Section 5.2.3.2, Step 5-7) and then the
BBU module (See Section 5.4.2, Step 2-3) back to
their original locations.
