2.9 BBU
Installation
(for the single-controller S12E-G1133-2)
The BBU can sustain cache memory in the event of a power failure
or in the 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 S12E-G1133-2 and can be ordered
separately from your subsystem vendor. You may skip this section if
you are using an S12E-R1132-4 redundant-controller subsystem
because two (2) BBUs come as pre-installed components.
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.
