Identify Startup Problems

Startup problems are commonly caused by source power problems or a board (network processing engine or cable interface line card) that is not properly connected to the midplane. With the exception of the fan tray and network processing engine, LEDs indicate all system states in the startup sequence. By checking the state of the LEDs, you can determine when and where the system failed in the startup sequence.

1.First check that you are properly plugged into the power source. Then verify that the line cards are properly installed.

2.The system cannot operate unless the network processing engine is installed properly. Check that the NPE is properly installed in the chassis.

3.Always verify that the fans are operating.

Queued messages:

%ENVM-1-SHUTDOWN: Environmental Monitor initiated shutdown

If the above message is displayed, it indicates that the system has detected an overtemperature condition or power out-of-tolerance condition inside the chassis. The shutdown message could also indicate a faulty component or temperature sensor. Before the system shuts down, use the show environment or show environment table command to display the internal chassis environment.
