Disconnecting the BBU from a PERC 6/i Adapter
or a PERC 6/i Integrated Controller
NOTE:
A PERC 6/i adapter installed in a Dell workstation or a Dell SC system does not
have a BBU.
NOTE:
Batteries with low charges can be detected and recharged. The battery
must first be charged and the system must be restarted for the battery to be active
again.
This section describes how to disconnect the BBU on a PERC 6/i adapter or a
PERC 6/i Integrated controller while the adapter or controller is installed in a
system.
1 Perform a controlled shutdown on the system in which the PERC 6/i is
installed.
2 Disconnect the system from the electrical outlet and remove the system
cover.
CAUTION:
Running a system without the system cover installed can cause damage
due to improper cooling.
NOTE:
For more information on removing and replacing the system cover,
refer to the Hardware Owner’s Manual that shipped with the system.
3 Determine whether the dirty cache LED on the controller is illuminated.
• If the LED is illuminated, replace the system cover, reconnect the
system to power, turn on the system, and repeat
step 1 and step 2 .
NOTE:
The location of the PERC 6/i varies from system to system. For
information on PERC 6/i card location, see the Hardware Owner’s
Manual that shipped with the system.
• If the LED is not illuminated, continue with the next step.
4 Locate the battery cable connection on the controller and disconnect the
battery.
