5-8 Subsystem Maintenance
Step 6. Power up the system. Please follow the correct power up
sequence that is described below.
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 from another source 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
causing it to leak acid 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 and 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 your Galaxy subsystem vendor.
