Local -941- Transceiver loopback error
Explanation: The Ethernet external loopback test has failed. This might occur when:
• There is a fault in the external Ethernet cabling.
• The access server is not connected properly to its transceiver.
• The transceiver is faulty.
• If you are using a fiber-optic transceiver, the remote end of the connection is not
operational. For more hardware information, refer to your access server hardware
documentation.
Step Action
1 Verify that the transceiver cable is connected securely at both ends. Also, inspect the
cable for any signs of damage. If the cable appears damaged, replace it and run the
self-test again.
2 Verify the Ethernet connector selected for the Ethernet loopback test.
3 If you are using standard Ethernet, inspect the transceiver cabling between the access
server and the coaxial cable.
4 If you are using ThinWire Ethernet cable, verify that the access server, ThinWire
cabling, or ThinWire are terminated.
