An AC-input power supply has the following features (see Figure 1-14 ):
• 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 1-9
summarizes the function of these indicators.
