Cisco CRS PDU Kit for Cisco CRS 16-Slot Line Card Chassis
This section describes the Cisco CRS PDU kit for the Cisco CRS 16-slot line card chassis.
The PDU has power input and power output cords entering and exiting the box. One single PDU is required for each modular
configuration AC power shelf installed in the chassis for system redundancy. Each PDU kit includes two single PDUs, either AC
Delta (Cisco product number PDU-321-6-Delta) or AC Wye (Cisco product number PDU-321-6-Wye), with 19-inch rack-mounting
brackets pre-installed, and chassis mounting brackets for alternative mounting. The left and right chassis mounting brackets are not
shipped pre-installed on the PDU. For information on how to install the PDU to the side of the Cisco CRS 16-slot line card chassis,
