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
Note
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

Basic Chassis Power Details
The Cisco CRS Series Enhanced 16-slot Line Card Chassis can be configured with either an AC-input power
system or a DC-input power system. Site power requirements differ, depending on the source voltage used.
Follow these precautions and recommendations when planning power connections to the router:
• Check the power at your site before installation to ensure that you are receiving clean power. Install a
