After successful power-up, the STAT LED turns ON on the Ethernet side. Then the
STAT LED should be green for a brief moment. The LAN LED turns ON when it is
connected to the network and blinks when there is traffic. The LAN LED remains
OFF if the module is not connected to the network.
3. If the STAT LED is amber, check the PLC Fault Table. With the Station Manager
feature, you can also use the LOG command as explained in the VersaMax PLC
Ethernet Station Manager Manual ( GFK-1876).
If a problem occurs during power-up, the Ethernet interface may not begin operating.
Check the Ethernet LEDs, as explained on the following table.
