Line Cards

An AC-input power supply has the following features (see Figure 1-7):

•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.

•Each AC-input power supply weighs approximately 14 pounds (6.4 kg), and can deliver up to 1400 W for original versions, or up to 1950 W for enhanced versions of the router.

•Each AC-input power supply requires a dedicated 20A service in North America (16 A international).

•A power standby switch on the faceplate temporarily disables the DC output power circuitry in the AC-input power supply.

Note This switch does not interrupt the incoming AC power in the AC-input power supply. Portions of the power supply circuitry are still under AC power as long as AC power is connected to the router.

•A handle is provided for ease in removing and replacing the power supply.

•Captive screws on the power supply ejector levers secure it in the power supply bay.

•Two LEDs on the faceplate to provide status information. Table 1-1 summarizes the function of these indicators.
