The problem could be a
loose cable connection.
Check all extension cables
are properly connected.
If this does not solve the
problem, continue along this
path of the flowchart.
A
Perform a module loopback
test on the NIC.
B
Perform an NCL loopback
test on the adapter cable
attached to the faulty port.
Load the DECNIS software.

Test
successful?
(READY state)
Perform NCL loopback tests on the extension cables.
If there is more than one cable, test all cables in sequence:
1. Test the cable nearest the adapter cable.
2. If that cable passes the test, test the next section of cable.
3. Repeat step 2 until all sections of the cable have been
tested, or the test fails.
B
All
tests successful?
