5.3. Replacing a Failed BBU Component
5.3.1 Replacing the BBU Module
NOTE:
When replacing a BBU in a single controller model, the whole subsystem needs to be
powered down. Therefore, when replacing a failed BBU, you should carefully select
the time at which the replacement will be made to minimize the overall disruption to
the service.
CAUTION!
• Install or replace the BBU with BBUs supplied by your subsystem vendors
only. Use of battery cells provided otherwise will void our warranty.
• Always dispose of discharged or used batteries in an ecologically responsible
manner. Dispose of used BBUs at authorized 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 leading
it to acid leak and resulting 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
causing 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 against a hard surface. These actions could damage or deform
it and internal short-circuiting can occur, possibly causing 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 RAID or your
subsystem vendor.
BBU failure can result from the following:
1. A BBU (battery cell pack) 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.
