BBU and FBM Installation
BBU Module Installation Overview
The BBU module is an optional item for some models. It can sustain
cache memory in the event of a power failure or in the unlikely event
of failing both PSUs. A BBU is highly recommended. The optional
BBU provides additional data security and helps minimize the loss of
data during power outage.
The BBU module is inserted into a module slot on the controller
module. The BBU module is secured with two (2) retention screws.
BBU Warnings and Precautions
Install or replace the BBU module only with a BBU module
supplied by your subsystem vendor. Use of battery cells
provided by another source will void our warranty.
Always dispose of discharged or used batteries in an
ecologically responsible manner. Dispose used BBUs at
authorized battery disposal sites only.
Do not use nor leave the BBU near a heat source. Heat can melt
the insulation and damage other safety features of battery cells,
possibly leading it to acid leak and result in flames or explosion.
Do not immerse the BBU in water nor allow it to get wet. Its
protective features can be damaged. Abnormal chemical
reactions may occur, possibly causing functional defects, acid
leak, and other hazardous results.
Do not disassemble or modify the BBU. If disassembled, the
BBU could leak acid, overheat, emit smoke, burst and/or ignite.
Do not pierce the BBU with a sharp object, strike it with a
hammer, step on it, or throw it. These actions could damage or
deform it, internal short-circuiting can occur, possibly causing
functional defects, acid leak, and other hazardous results.
If the BBU leaks, gives off a bad odor, generates heat, becomes
discolored or deformed, or in any way appears abnormal during
use, recharging or storage, immediately remove it from the
subsystem and stop using it. If this is discovered when you first
use the BBU, return it to your system vendor.
BBU Installation Procedure
Step 1.
Prior to installing the BBU module, power off the subsystem
or restart the subsystem after installation.
Step 2.
Use a screwdriver to
loosen the two (2) retention
screws located on the levers on both sides (see
below)
