Disconnecting the power cords from the 8202-E4B or 8205-E6B system

Use these procedures to disconnect the power cords from the 8202-E4B or 8205-E6B system.

1.For a rack-mounted system, open the back rack door on the unit you are servicing and identify the system unit you are servicing in the rack.

2.For both a rack-mounted system and a stand-alone system, disconnect all power cords from the unit you are servicing. This system might be equipped with two power supplies. Before continuing with any remove and replace procedures that require the power off, ensure that both power sources to the system have been completely disconnected.
