5.4 Replacing a Faulty BBU
IMPORTANT!
The BBU is hot-swappable, 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.
To replace a faulty BBU, please follow these steps:
Step 1. Remove the faulty BBU module from the chassis. The BBU
module is secured to the chassis with two (2) spring screws. These
screws must be loosened. To loosen, turn the screws
counterclockwise. (See Figure 5-4)

Step 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 5-5)

Step 3. Secure the BBU module to the enclosure. Tighten the two (2)
spring screws as shown above on the back of the BBU module.
