6.2 LED Status Indicators
ETH CFG

OK
The LEDs indicate the module’s operating status.
LED Color Indication
ETH Green Application is running and Ethernet is ready

During module configuration, the OK LED is red and the BP LED is on. If the BP
ACT and OK LEDs blink at a rate of every one-second, this indicates a serious
problem with the module. Call ProSoft Technology Technical Support to arrange
for repairs.
6.2.1 Clearing a Fault Condition
Typically, if the OK LED on the front of the module remains RED for more than
ten seconds, a hardware problem has been detected in the module or the
program has exited.
To clear the condition, follow these steps:
1 Turn off power to the rack.
2 Remove the card from the rack.
3 Verify that all jumpers are set correctly.
4 If the module requires a Compact Flash card, verify that the card is installed
correctly.
5 Re-insert the card in the rack and turn the power back on.
6 Verify correct configuration data is being transferred to the module from the
CompactLogix controller.
If the module's OK LED does not turn GREEN, verify that the module is inserted
completely into the rack. If this does not cure the problem, contact ProSoft
Technology Technical Support.
