Possible Cause

Possible Solutions

No optical signal output

(ALARM LED is Red)

The laser temperature
could be too high or low.

Allow up to one minute after
power is ON for the
temperature to stabilize.

If still no output, contact Cisco
Services for assistance.

The laser could be
faulty.

Contact Cisco Services for
assistance.

Automatic power
control circuit failure.

Contact Cisco Services for
assistance.

Damaged fiber.

assistance.

No optical signal output
(cont'd)

One or more power
supply voltages are out
of specification.

Check the power supply for
proper operation.

No AC at receptacle.

Check the receptacle for AC
power.
