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.
