Install the BBU.
Align the BBU with the BBU slot. Gently insert
the BBU until the back of the BBU reaches the end of the slot.
Step 5.
Secure the BBU to the chassis.
Fasten the hand screws on the sides
of the BBU faceplate to secure the BBU to the chassis.

Step 6.
If the subsystem has been powered on, the LED should start
flashing to indicate that the BBU is being charged. When the BBU
is fully charged, the LED will be turned off. (See
Figure 2-10
)

NOTE:
A new or replacement BBU takes at least seven (7) hours to charge to its
full capacity. Reset the subsystem whenever a BBU is replaced or added
for the new BBU to take effect.
NOTE:
The life expectancy of a BBU is more than one year. Follow the
procedures in Section 5.4 to replace a used BBU with a new one in order
to maintain fault tolerance features.
