EonStor S12F-R1432/G1433 Installation and Hardware Reference Manual
․
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 no matter how long the module has been used. Therefore,
a stable power source is important for system operation.
․
The charger circuitry implemented within the controller has
failed.
There are other conditions that might trigger the BBU fault events and
the BBU fault LED:
․
The temperature sensor embedded with the 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 your remove and then re-
install the BBU.

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
