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.

  1. Power off the storage controller as described in Powering Off the Controller.
  2. Disconnect the AC power cords from the rear panel of the storage controller.
    Caution

    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.

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