EonStor A16E-G2130-4 Installation and Hardware Reference Manual  
 
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 re-install the BBU 
module. 
 
5.4.1  BBU Warnings and Precautions 
  Install or replace the BBU with BBUs 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 BBUs 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 cause 
functional defects, acid leak, and other hazardous results. 
  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 deform it and internal short-circuiting 
can occur, possibly cause functional defects, acid leak, and other hazardous 
results. 
  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 subsystem and stop using it. If this is discovered 
when you first use the BBU, return it to Infortrend or your subsystem vendor.
