Running Self-Tests
The communications server runs a series of self-tests on powerup and reports test
status through the communications server LEDs. Refer to Figure 1-1.
Ensure that the ThinWire network connection to the BNC connector, or to the
DEChub 90, is properly terminated, or connected to an active network. Failure to
do this will cause the self-test to fail the network loopback test.
The following list describes the behavior of the LEDs during self-test.
•
Initially, all LEDs light briefly, then extinguish, leaving only the power LED
lit.
•
The Port Activity LEDs light one by one and remain lit, as the
communications server completes each segment of self-test. All eight
LEDs are lit once the tests have run successfully.
•
After successful completion of the self-tests, the Self-Test OK LED is lit, and
the eight port LEDs are extinguished.
To reset the communications server to the factory-default settings, press the
Reset switch after the Port 7 LED lights, but before the Port 4 LED lights during
self-test. Keep the reset switch depressed until the Network OK and Self-Test OK
LEDs flash rapidly. This indicates that the communications server has been reset
to factory settings.
Note
If a self-test pattern halts, an error condition has been detected. Refer to
the chapter on ‘‘Troubleshooting’’ in this manual.
