The Loopback Mode jumper is located on the media
converter’s circuit board (labeled ALL= all frames
plus errors, Good = Good frames only). See Jumper
position to the right.
Loopback test
The loopback test is an automatic test run from the center chassis converter with
SW6 set to ‘center,’ the UP position of the switch; and on the terminal converter
with SW6 set to ‘terminal,’ the DOWN position of the switch.
Note: This test is self-running after being initiated through software on the center
converter.
The Loopback test does the following:
1. The center converter will put the terminal converter in loopback mode.
2. The center converter sends 100 packets to the terminal converter.
3. The center converter will monitor its receiver for:
a. good packets
b. CRC errors
c. timeouts
4. After the center converter receives all 100 packets back or a time out occurs, it
will update its counters and return the terminal converter to its previous mode
of operation.
After completing the test, normal operation of the center and terminal converters is
established automatically.
