Troubleshooting the AC-Input Power Subsystem

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.
