EonStor S12S-R/G1032 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 your remove and then re-install the BBU.
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
leak, and other hazardous results.
