EonStor F16F-R/S4031 Installation and Hardware Reference Manual
Fault Conditions:
A BBU failure can result from the following:
1. 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.
2. The charger circuitry implemented within the controller has
failed.
There are other conditions that might trigger the BBU fault events and
trigger the BBU fault LED:
1. 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.
2. 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 then re-
install the BBU.
If the charger detects elevated temperature during the charging
process, the charging process may also be prolonged.
BBU Warnings and Precautions:
Install or replace the BBU with BBU’s supplied by your
EonStor vendors only. Use of battery cells provided otherwise
will void our warranty.
Always dispose of a replaced battery in an ecologically
responsible manner. Dispose of used BBU’s 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 battery cells,
possibly will cause acid leak and result in flames or explosion.
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 will cause functional defects, acid
