AC Power Systems
• Each AC PM requires its own single-phase AC input power feed, with it's own circuit breaker.
• The AC power receptacles used to plug in the chassis must be the grounding type. The grounding
conductors that connect to the receptacles should connect to protective earth ground at the service
equipment.
• AC single-phase input:
–
Single-phase, 200 to 240 VAC nominal, 50 to 60 Hz.
–
Each AC power tray contains three IEC-320-C22 receptacles, which can accept up to three
IEC-320-C21 connector female plugs, depending on how many AC PMs are installed in the tray.
• The AC power system requires single-phase AC input power to each PM. If you have 3-phase AC
Delta or AC Wye at your equipment, a Cisco NCS 3-phase AC PDU is required to convert 3-phase
AC input power to single-phase AC input power (Cisco PID NCS-PDU-DELTA or
NCS-PDU-WYE). For more information, refer to the Cisco 3-Phase AC Power Distribution Unit
Installation Guide on Cisco.com.
Note If you have a 3-Phase AC PDU installed, we recommend you install three AC PMs in each AC power
tray to maintain a balanced 3-phase power load.
For detailed AC power specifications, see the “Power Specifications” section on page 3-2.
AC Power Tray Wiring
The AC power tray is shipped with AC power cords. Each AC power tray accepts up to three power cords.
Each AC power cord has a different plug type, depending on locale. AC power cords are available for
the locales listed in Table 2-1.
