What to do if the Fault LED is blinking amber on Nortel Passport 8000?
- TTrevor CarrilloAug 16, 2025
If the Fault LED on your Nortel Chassis is blinking amber, it indicates a chassis failure. Use the `show log` command from the console management station to check the system log for information about hardware failures. Also, verify that both fans are running in the fan tray, and check the switch power supplies to ensure they are functioning correctly. The module may have failed to read the MAC address from the chassis backplane. If this is the case, arrange to replace the chassis.
