Fiber Continuity Tests
When there is a problem communicating over a particular fiber link and both the
Switch and the N_Port adapter pass their respective tests, check the continuity of
the fiber optic cables.
Step 1
If possible, swap another set of fiber optic cables into the faulty link.
Did this correct the problem?
Yes Replace the faulty cable.
No
Contact your service representative.
Step 2
If it is not possible to swap a different set of fiber cables into the faulty link,
disconnect the SC connectors from both ends of the faulty link and shine a
flashlight through each fiber (one fiber at a time).
Did light shine through each fiber?
No
Replace the faulty cable.
Yes Contact Ancor Customer Service or your authorized maintenance provider.
