Troubleshooting the Power Subsystem
For the RP card to communicate properly to a power module, input power to at least one of the two power
modules 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 RP. If the
router detects an extreme condition, it generates an alarm and logs the appropriate warning messages on the
console.
The following figure shows the status indicators for the power module.
