Installing CBM for RAID Models
The CBM consists of a BBU and FBM. The CBM can sustain the cache memory in
the event of a power failure or in the extremely unlikely event of both PSUs failing
simultaneously. Use of a CBM is highly recommended in order to safeguard data
integrity. The CBM is an optional item for the single-controller model and can be pur-
chased from your system vendor. The CBM must be installed on the controller before
rack-mounting the system.
Note!
Dual-controller model's BBU and FBM are pre-installed!
Dual-controller systems are equipped with the BBU pre-installed in the
system. A FBM may be provided by default or as an optional item. For
further details, please refer to CBM for RAID Models.
For single-controller models, the CBM (BBU + FBM) will be pre-installed
if ordered as a part of the system. If the CBM is purchased afterwards as
an upgrade component, please read and follow the instructions in this
section carefully.

Flash Backup Module and Battery Backup Unit
Please read the following sections on how to install the battery backup module and

surface and hold the controller only by its metal canister. Never touch the circuit
board or connector pins.
