Troubleshooting a Routing Engine Failure
During Power-On Self-Test
When a routing engine failure occurs during the power-on self-test, as
indicated by the LED pattern shown for that failure in table 3-1:
1. If, at the end of the self-test any of the first four routing engine
utilization LEDs is lit (but none of the others is lit), replace the
routing engine. (All of the routing engine utilization LEDs are lit at
the beginning of the self-test.)
2. Connect a console to the router, with the PC or terminal set to 9600
baud.
3. Switch the router power off and on.
4. If an error message appears on the console, use the procedure in
table 3-4.
