Interpret the LED Indicators
If your module is operating correctly, you see:
• Status LED indicator remains lit green
• Ethernet Transmit LEDs briefly light green when transmitting packets
If the LED indicators do not indicate the above normal operation, refer to the following
table.
LED Indicator Descriptions
TCP tcpInSegs Number of segments received
tcpOutSegs Number of segments sent
tcpRetransSegs Number of segments retransmitted
tcpInErrors Number of segments discarded due to format errors
tcpOutRsts Number of resets generated
tcpConnState State of connection
tcpConnLocalAddress Local IP address
tcpConnLocalPort Local TCP port
tcpConnRemAddress Remote IP address
tcpConnRemPort Remote TCP port
Indicator Color Description Probable Cause Recommended Action
STAT Solid red Critical hardware fault. Module requires internal
repair. Contact your local
Allen-Bradley distributor.
Blinking red Hardware or software fault (detected
and reported via a code). Fault-code dependent. Refer to module error codes.
Off Module is functioning properly but it is
not attached to an active Ethernet
network. Normal operation. Attach the controller and
interface module to an
active Ethernet network.
Green Ethernet channel 3A is functioning
properly and has detected that it is
connected to an active Ethernet network. Normal operation. No action required.
100M or
10M Green Lights (green) briefly when the Ethernet
port is transmitting a packet. It does not
indicate whether or not the Ethernet port
