EonStor DS S12/S16/S24 Series Hardware Manual
The CBM can sustain and transfer cached data to a flash backup module in the event
of a power outage or in the unlikely event of both PSUs failing.
The CBM (BBU and FBM) might be optional items depending on the subsystem
model. For details, see

5.3.1
BBU Fault Conditions and Precautions
If a 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 system and stop using it. Here are some of the
conditions that might trigger BBU fault.
The temperature sensor on the system’s charger circuit reports a temperature
reading exceeding the pre-set threshold. The charger circuits will enter a
low-power and self-protection state.
A BBU module has been charged for over twelve hours. A timer is embedded with
the charger. When this occurs, the charger will enter a timer fault state. Charging
will resume automatically after you remove/re-install the BBU module or reset the
system.
Follow these precautions when you install the BBU.
Use the replacement BBU supplied by InforTrend. Use of battery cells provided
otherwise will void your warranty.
Dispose of used BBUs at authorized battery disposal sites only.
Do not place a BBU near a heat source.
Do not immerse the BBU in water nor allow it to get wet.
Do not disassemble or modify the BBU.
Do not pierce the BBU with a sharp object, strike it with a hammer, step on it, or
throw it.
