Troubleshooting the AC-Input Power Subsystem
Cisco 12016, Cisco 12416, and Cisco 12816 Router Installation and Configuration Guide
5-6
AC-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 12016, Cisco 12416, and Cisco 12816 series routers are available with
either an original (2000 W) or enhanced (2500 W) capacity AC power supply:
