Connecting to an AC Power Source

This section presents the procedure for connecting your router to an AC power source.

•Original series Cisco XR 12406 routers: A power factor corrector (PFC) allows the power supply to accept AC power source voltage from an AC power source operating from 100 to 120 VAC 20-amp service in North America, and a range of from 185 to 264 VAC 16-amp service in an international environment.

•Enhanced series Cisco XR 12406 routers: Supports 220 VAC only which requires 20-amp service in North America, and 16-amp service in an international environment.

Warning The AC-input PEM power switch should be in the off position before connecting to an AC power source.

When operating your router on a power source, the power supply bays must have one of the following power combinations installed before operating the router (Table 3-6):
