Failing this test indicates that either the Remote Annex 4000, its
transceiver cable, its transceiver, or the Ethernet, is bad. Isolate the
failure by using this test and the Ethernet loopback connector. Any
of the following conditions can cause these test failures:
1
The Remote Annex 4000 has faulty Ethernet port electronics.
To test for this condition, connect the Ethernet loopback
connector directly into the network connector. Run the net test
again. If errors still occur or the +12-volt LED on the 10Base5’s
loopback connector fails to light, the problem is with the Remote
Annex 4000. Call technical support.
2
The Remote Annex 4000 transceiver cable is defective or
disconnected (this problem occurs only with the 10Base5 interface).
To test for this condition, connect the 10Base5’s loopback
connector to the transceiver end of the transceiver cable (while
the cable is connected to the Ethernet port) and run the net test.
If errors did not occur during the first test run, but do occur
during this test, the cable is faulty and should be replaced.
3
The transceiver at the end of the transceiver cable is defective or
improperly connected to the Ethernet.
If the cable is free of faults (tested as described above) and other
devices on the Ethernet are not experiencing difficulties, the
problem is in the transceiver. If you have already ruled out the
transceiver, contact technical support.
4
The Ethernet cable is shorted or improperly terminated.
Other devices on the net should show evidence of problems.
