Prerequisites
Before performing this task, perform the following procedures:
If you have AC Delta or AC Wye at your equipment, ensure that two Cisco CRS PDUs are installed to convert
3-phase AC input power to single-phase AC input power for the power shelves. For further information, refer
to Cisco CRS 3-Phase AC Power Distribution Unit Installation Guide .
If you have a Cisco CRS PDU installed, the AC power cords must be installed as labeled. For further
information, refer to the Cisco CRS 3-Phase AC Power Distribution Unit Installation Guide .
Note
Before installing input AC power cords on the power shelf, make sure that the input power cords are not
energized.

Steps
To install the input AC cord, go to the rear (MSC) side of the chassis and perform the following steps:
SUMMARY STEPS
1.
Insert the cord plug into the cord clamp (see Figure 24: Cord Being Inserted into Cord Clamp, on page
36) following the labeling on the phase assignments from the PDU or the labeling on the single phase
power cords. As viewed from the front, the PDU on the right side is power shelf B and the PDU on the
left side is power shelf A.
