User-Initiated Diagnostics
You can initiate a complete test of the NIM hardware, including the communication
ports. Complete the following steps to start the NIM diagnostics.
CAUTION
Since this test includes the communication ports, it is
necessary that the NIM be disconnected from the TIWAY
network.
1. Disconnect network cables from both NIM network ports.
2. Install loopback connectors (part no. 2641307–0001) on the NIM RS-232-C
port(s).
3. Make certain the LOCAL/REMOTE switch is in the “Local” position.
4. Press the RESET switch.
5. Press the TEST switch.
At the start of the diagnostics, the TEST LED will be on, with all other LED indicators
off. Then, after approximately ten seconds, all LED indicators will flash on and off for
approximately two seconds. When the diagnostics are finished, the TEST LED will flash
at a 2 HZ rate.
If the NIM completes the tests without errors, the following LED indicators will be on.
