Troubleshooting the KFC15 Module
Use this chapter to interpret the indicators (status LEDs and dot
matrix display) on the KFC15 module to help you troubleshoot
problems.
Interpreting the Status LEDs
There are three, bi-color (red/green) status LEDs on the top of the
KFC15 module. Two are for ControlNet, showing the physical layer
status of channels A (primary connection) and B (redundant media
connection), and one is for the KFC15 (STATUS). These indicators
can help you diagnose problems with the module’s installation and
operation.
