External ring test

The External Ring test verifies that all hardware to the network is operational. It is available for token-ring networks and distributed data interfaces. To run this test, all hardware must be connected as it would be in normal operation. This test allows a signal to be sent through the network and wrapped (no wrap connectors are required).

If the test completes successfully, the adapter, cable, and access unit are operating correctly.

For further problem analysis if the test fails, run the cable and I/O adapter tests in the order in which the display lists them.
