Step 2.
Install the replacement 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
)
