5-11
To replace a BBU, please follow these steps:
Step 1.
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
)

Step 2.
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.
Step 3.
Secure the BBU to the subsystem
by fastening the two (2)
retention screws. (See
Figure 5-9
)

Step 4.
The LED should start flashing to indicate that the BBU is
being charged. When the BBU is fully charged, the LED will
go off. (See
Figure 5-10
)
