Table 3-5 lists IEEE 802.3u physical characteristics for 100BASE-TX.
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
