Make sure that each power cord is connected to a dedicated AC power

source.
Each AC power supply operating in the nominal range of 200 to 240 VAC
–
requires a minimum service of 20 A, North America (or 13 A,
international).
Because both the standard and optional AC-input power subsystems use
redundant power supplies, a problem with the DC output voltage to the backplane
from only one power supply should not affect router operation. When the router
is equipped with two AC power supplies, it powers on and operates even if one
power supply fails.
DC-input power supplies are monitored for internal temperature, voltage, and
current load by the MBus module on the alarm cards, and by the master MBus
module on the RP. If the router detects an extreme condition, it generates an alarm
on the alarm card and logs the appropriate warning messages on the console.
Cisco 12010, Cisco 12410, and Cisco 12810 series routers are available with
either original or enhanced capacity DC power supplies:
