EonStor S12E-R1132-4/G1133-2 Installation and Hardware Reference Manual
A BBU failure can result from the following:
․
A BBU has lost its ability to hold electrical charge. This may be
the case after the battery cells have been recharged for many
times regardless of how long the module has been used.
Therefore, a stable power source is important for system
operation.
․
The charger circuitry implemented with the controller has failed.
There are other conditions that might trigger the BBU fault events
and trigger the BBU fault LED:
․
The temperature sensor embedded with the subsystem’s
charger circuit reports a temperature reading exceeding the
preset threshold. The charger circuits will enter a low-power
and self-protection state.
․
A BBU module has been charged for over twelve (12) hours. A
timer is embedded with the charger. When this occurs, the
charger will enter a timer fault state. The fault condition usually
occurs with a brand new BBU or with a totally discharged BBU.
Charging will resume automatically if you remove and re-install
the BBU module.

BBU Warnings and Precautions
․
Use of battery cells provided otherwise will void
our warranty.
․
ose of used BBUs at authorized
battery disposal sites only.
․
,
possibly will cause acid leak and result in flames or explosion.
․
use functional defects, acid
leak, and other hazardous results.
․
Install or replace the BBU with BBUs supplied by your EonStor
vendors only.
Always dispose of a replaced battery in an ecologically
responsible manner. Disp
Do not use nor leave the BBU near a heat source. Heat can melt
the insulation and damage other safety features of battery cells
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 ca
Do not disassemble or modify the BBU. If disassembled, the
BBU could leak acid, overheat, emit smoke, burst and/or ignite.
