Chapter 3 ROM Monitor Commands
Failing this test indicates that either the Remote Annex 6300, 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:
1The Remote Annex 6300 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
2The Remote Annex 6300 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.
3The 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.
4The Ethernet cable is shorted or improperly terminated.
Other devices on the network should show evidence of problems.
