Installing Modular Configuration AC Power Shelf Wiring
This section describes how to install input AC power cords on the modular configuration AC power shelf.
Note When wiring the power shelf, be sure to connect the chassis ground cable first.
Prerequisites
Before performing this task, ensure that both power shelves are installed in the chassis.
If you have AC Delta or AC Wye at your equipment, a Cisco CRS PDU will be required to convert
3-phase AC input power to single-phase AC input power for the power shelf. For further information,
refer to Cisco CRS 3-Phase AC Power Distribution Unit Installation Guide.
Note Before installing input AC power cords, make sure that the AC power cords are not energized.
