Attach the Power Cords

The power cords for the switch ship separately and are specific to the country of installation. 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 front of the chassis, standby and main power is made available by the power supplies. When standby power is distributed to the chassis, the management controller is powered on. The main power is supplied for the switch chips and fans.

1. Identify the prerequisite and subsequent installation tasks that you must perform in conjunction with this procedure.

   See Installation Sequence.

2. Ensure that the circuit breakers for the power supplies are switched off.

3. Plug a power cord into each power receptacle at the front of the chassis.
