Power Failure Troubleshooting Procedures

The following illustrates the steps to take when either the PWR A or PWR B

LEDs, or both, are OFF.

1.Using a voltmeter, check for power at the terminal connections.

ÐIf there is power, call your sales representative for service to the 8600.

2.If there is no power at the terminal, call the appropriate electrician.

Power LED is OFF

PROBLEM: One of the DC PWR LEDs is OFF due to a failure in a single chassis within a stack.

ACTION: Go to the stack to see which chassis has the power failure. To clear the power alarm, remove the power from the chassis and disconnect the powered-off chassis from the management daisy chain (bypassing the failed chassis). Follow the appropriate power failure troubleshooting procedure described above.
