Diagnostic Tips
Power Supply Failure
1. Open the router door, and check the LEDs on the switches
of the power supplies.
2. For the power supply on which the switch LED is not lit,
verify that the power cable is securely connected to the
power source and to the proper receptacle on the back of
the router.
3. If the power cable is connected properly, replace the
power supply.
Cooling Module Failure
Replace the cooling module.
Temperature Warning
If the Fan LED is not lit and the router is mounted in a cabinet,
verify that the airflow around the router is not restricted. The
temperature where the router is installed should be within
the range specified in appendix C.
