Thanks for all of the suggestions everyone. The problem turned out to be that I did not have the SQE(heartbeat) switch set on the transceiver. After I flipped that switch and restarted the system, no more blinking led. Since everything else seemed to be working correctly with the switch in the "wrong position", (talking on the lan ok, linkcontrol showing no errors, nothing in the NMLG@ files, etc.) in my mind, this begs the question, "is there more to the SQE signal than keeping a led from being lite"? I'm sure there is, but there was certainly nothing apparent? Thanks again to everyone that responded.
