Module Diagnostics
Modules are equipped with a status indicator LED that can help troubleshoot possible
issues. Under normal operation, the status indicator LED should flash once every 4
seconds.
If a module is blank, but has power supplied to it, perform a module self-test to diagnose
a module or signal cable failure.
To perform a self-test, follow the steps below.
1.
Attach a signal cable to Port A and Port B on the module, as shown in
.
2.
Disconnect the power to the module for 10 seconds.
3.
Reconnect the power to start the self-test.
4.
Verify the module is running a self-test.
Remove the signal cable and cycle power to the module to stop the self-test.
