This section contains information to troubleshoot the power subsystems:

For the RSP/RP card to communicate properly to a power module in a power tray, input power to at least 
one of the three power modules in the power tray should be present.

AC input power modules are monitored for internal temperature, voltage, and current load by the 
RSP/RP. If the router detects an extreme condition, it generates an alarm and logs the appropriate 
warning messages on the console.
