Replacing a Faulty BBU
Chapter 5: Subsystem Maintenance and Upgrading
Remove the faulty unit from the chassis by using a medium-
size Phillips screwdriver to loosen the two (2) retention screws
located on the sides, then pulling out the BBU. (See Figure 5-
8)
Figure 5-8: Removing the BBU
Install the new BBU. Align the BBU with the slot, and then
gently push the BBU into the slot. When you feel the contact
resistance, use slightly more force for the back-end connector
to mate with the backplane.
Secure the BBU to the subsystem by fastening the two (2)
retention screws. (See Figure 5-9)
Figure 5-9: Installing the BBU
The LED should start flashing to indicate that the BBU is

go off. (See Figure 5-10)
