Optional Battery Module Installation
The BBU can sustain cache memory in the event of a power failure
or in the extremely unlikely event of failing both PSUs. The use of a
BBU is highly recommended in order to avoid data inconsistency.
The BBU is an optional item for the S12S series and can be ordered
separately from your subsystem vendor (PN: IFT-9275CBTE). Read
the BBU handling precautions in
Section 2.9.1
before replacing it.
Please follow the steps in
Section 2.9.2
to install a BBU into your
system.
2.9.1
BBU Warnings and Precautions
Install or replace the BBU with BBUs supplied by your vendors
only. Use of battery cells provided from another source will void
your warranty.
Always dispose of used batteries in an ecologically responsible
manner 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 the battery
cells, possibly causing an acid leak and may result in a fire or
explosion.
Do not immerse the BBU in water nor allow it to get wet. Its
protective features can be damaged and abnormal chemical
reactions may occur, possibly causing functional defects, acid
leaks, and other hazardous results.
