/i Controller
This section describes the procedure to disconnect the BBU on a PERC x /i
Adapter or PERC x /i Integrated controller while it is installed in a system.
CAUTION:
Only trained service technicians are authorized to remove the system
cover and access any of the components inside the system. Before performing any
procedure, see your
Product Information Guide for complete information about
safety precautions, working inside the computer, and protecting against
electrostatic discharge.
NOTE:
PERC x /i Adapters installed in Dell Precision™ workstations or PowerEdge
SC servers do not have a BBU.
1
Perform a controlled shutdown of the system in which the PERC x /i
controller is installed.
2
Disconnect the system from the electrical outlet and remove the system
cover.
NOTE:
See the Hardware Owner’s Manual included with the system for more
information on removing and reinstalling the system cover.

Locate the PERC x /i controller in the system and visually inspect the
controller to determine whether the dirty cache LED on the controller is
turned on. If the LED is turned on, replace the system cover, reconnect
the system to power, turn the system on and repeat steps 1 and 2.
CAUTION:
Running a system without the system cover installed may cause
damage due to improper
cooling.

Locate the battery cable connection next to the memory module on the
controller, and disconnect the battery.
See the Hardware Owner’s Manual included with the system for information
on removing the BBU from the system chassis. The location of the TBBU
for the PERC
