Replacing a 7x20 Battery
You might need to replace the battery if the storage controller fails to
maintain the proper time when powered off and disconnected from the network. You
will need a small (No.1 flat-blade) non-metallic screwdriver or equivalent. Use
the following procedure to replace a 7x20 battery.
-
Power off the storage controller as described in Powering Off the Controller.
-
Disconnect the AC power cords from the rear panel of the storage
controller.
| Caution -
Because 3.3 VDC standby power is always present in the system, you
must unplug the power cords before accessing any cold-serviceable
components.

-
Extend the controller from the rack as described in Extending the Controller from the Rack.
