Replacing a Faulty BBU Module

 

The BBU module is installed in the rear panel of the subsystem above the controller module. It

 

consists of a battery cell pack enclosed in a metal bracket and connects directly to the back-

 

plane board.

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 module from the chassis. The BBU module is secured to the chas- sis with two (2) spring screws. These screws must be loosen. To loosen, turn the screws counterclockwise. (See Figure 6.4)

Fig. 6.4 Remove the Metal Sheet Retention Screws

2.Install the new BBU module. After the faulty BBU module has been removed, the new BBU module can be installed. To do this, align the BBU module with the empty slot, and then gently push the BBU module into the slot. (See Figure 6.5)
