Troubleshooting
Interpreting LED Error Patterns
After trying each diagnostic tip in table 3-2 below, reboot the router as
directed; if a failure then occurs, use table 3-1, "LED Error Patterns
During Power-On Self-Test," to interpret the LED error patterns.

Diagnostic Tips
Routing Engine Software Failure
If this error occurs, this pattern of LEDs appears only for a
few seconds until the router reboots (which will occur unless
Auto Reboot in the configuration has been disabled). If Auto
Reboot has been disabled, press the Reset button on the
routing engine to force the router to reboot.
After the router reboots, information about the failure will
appear in the crash history (which can be displayed using
NCL's Crash command) and in the event log (which can be
displayed from the Main menu).
Interface Card Software Failure
If this error occurs, this pattern of LEDs appears only for a
few seconds until the router reboots (which will occur unless
Auto Reboot in the configuration has been disabled). If Auto
Reboot has been disabled, enable the card either by hot-
swapping it (do steps 1–5 and 8–11 of the procedure "Replac-
ing an Interface Card [System Online], page 3-21) or by using
NCL's Enable command (see the Operator's Reference ).
Information about the failure will appear in the crash history
(which can be displayed using NCL's Crash command) and in
the event log (which can be displayed from the Main menu).
Interface Card Apparently Not Present
1. If there is an interface card in this slot, verify that it is
seated properly in the router slot.
2. If this error persists, switch the power off and on, then
check the LEDs for failures as indicated in table 3-1.
