Connecting an AC Power Supply to AC Power Sources

If you are powering your Cisco Nexus 7000 Series switch with 3-, 6-, or 7.5-kW AC power supplies, you
must connect those power supplies to an AC power source. When you connect the power cable to the AC
power grid and the power supply, the power supply is automatically grounded through this cable.
Before you connect the power supplies to their power sources, you must have already connected the
chassis to the earth ground. If the chassis is not yet grounded, see the following sections:

For the Cisco Nexus 7009, 7010, or 7018 chassis, the front of the power supply is touching the front
of the chassis and the four captive screws on the front of the power supply are aligned with four
screw holes in the chassis.
