Troubleshooting the Power Subsystem
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.
Note
Troubleshooting the AC Input Power Subsystem
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.
The figure titled "Version 1 Power Module Status Indicators" shows the status indicators for the version 1
power module. The figure titled "Version 2 Power Module Power Module Status Indicators" shows the status
indicators for the version 2 power module, and the figure titled "Version 3 AC Power Module Status Indicators"
shows the status indicators for the version 3 AC power module. The indicator definitions follow the two
figures.
