Cords and
Receptacles
Each E5400 controller-drive tray is shipped with two AC power cords, which use the
standard AC outlets in the destination country. Each AC power cord connects one of
the power supplies in the drive tray to an independent, external AC power source,
such as a wall receptacle, or to any uninterruptible power supply (UPS).
If you have a cabinet with internal power cabling, such as a ladder cord, you do not
need the AC power cords that are shipped with the controller-drive tray.
DC power is an option that is available for use with your controller-drive tray and
drive trays.

controller-drive tray. The three source wires on the other end of the power connector
cable connect the controller-drive tray to centralized DC power plant equipment,
typically through a bus bar above the cabinet.
