Replacing a Faulty BBU Module

 

The BBU consists of a bracket, a battery pack, and a PCB board that connects to the back-

 

plane board. If a BBU was installed and has failed, it should be replaced. To install or replace

 

a BBU, please follow these steps.

BBU Warnings and Precautions

•

Install or replace the BBU 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 used BBU at authorized battery disposal sites only.

Do not use nor leave the BBU near a heat source. Heat can melt the insulation and dam- age other safety features of battery cells, possibly leading it to 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 causing functional defects, acid leak, and other hazardous results.

Do not disassemble or modify the BBU. If disassembled, the BBU could leak acid, over- heat, 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, internal short-circuiting can occur, possibly causing functional defects, acid leak, and other hazardous results.

If the 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 Bosch or your system vendor.

6.4.2Procedure

i

NOTICE!

The BBU is hot-swappable and can be replaced while the subsystem is running. However, a new module will only be recognized after a subsystem reset. Carefully select the time when the reset will be made in order to minimize the overall disruption to service.

1.Remove the faulty BBU from the chassis. Loosen the two (2) retention screws located on both sides of the BBU, then pull out the BBU. (See Figure 6.8)

Fig. 6.8 Removing the BBU Module

2.Install the new BBU. Align the BBU with the slot, and then gently push the BBU into the slot.

3.Secure the BBU to the subsystem by fastening the two (2) retention screws on the back of the BBU (See Figure 6.9)
