Power Systems Overview
The chassis power system provides power to chassis components and is made up of two AC or DC power
shelves that contain AC or DC power modules (PMs) and alarm modules.
The AC power system requires single-phase AC input power to the power shelves. If you have 3-phase AC
Delta or AC Wye at your equipment, a Cisco CRS power distribution unit (PDU) will be required to convert
3-phase AC input power to single-phase AC input power for the power shelf. The power system also includes
SNMP MIBS and XML support.
In the AC power system, PDU refers to the Cisco CRS PDU which is required to convert 3-phase AC-Wye
or AC-Delta input power to single-phase AC input power for the AC power shelf. For further information
and installation instructions, refer to the Cisco CRS 3-Phase AC Power Distribution Unit Installation
Guide .
