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 rear of the chassis, standby and 12 volt power is made available by the power supplies. When standby power is distributed to the chassis, the CMCs are powered on. The 12 volt power is supplied for the fabric cards and line cards.

1. Identify the prerequisite and subsequent tasks you must perform in conjunction with this procedure, to install the switch.

   See the table in 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 rear of the chassis.

   
   

4. Route each power cord to its respective facility power receptacle.

   Use cable ties or hook and loop fastener straps to bundle and secure the cord.

5. Plug each power cord into the receptacle.

6. Energize the circuit breakers so that the power receptacles are live.

7. Verify that the status LEDs for each power supply indicate normal operation.

   The OK LED should be lit and the Attention LED should be unlit. See Check the Power Supply Status LEDs.
