Power supply failure
Symptom
The LEDs for the power supply are in the following states:
•
On the MPU, the PWR OK LED is off and the PWR FAIL LED is on.
The PWR OK LED is on and the PWR FAIL LED is off only when all the power supplies are
operating correctly. When a power supply is faulty, the OK LED is off and the FAIL LED is on.
•
On the power supply, the INPUT OK LED is off, or the OUTPUT OK LED is amber or red.
For more information about the LEDs, see "Appendix C LEDs."
NOTE:
After a power supply is removed from the router, the input and output LEDs on the power supply stay
on for several seconds.
