## Power On the Switch

The power cords for the switch ship separately and are specific to the country of installation. See Power Cord Specifications. The facility power receptacles for the power cords should be located such that the power cords are routed out of the way, either to the sides of the rack or under the floor.

When live power is delivered to the receptacles at the rear of the switch, standby and main power is made available by the power supplies. When standby power is distributed to the switch, the management controller is powered on. The main power is supplied for the switch chip and fans.

1. Install the switch in the rack and attach the management cables.
