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 four
seconds.
Module Self-Test
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
these steps:
1� Attach a signal cable to Port A and Port B on
the module. Refer to Figure 23 .
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.
