It is a 1768-L45. I had thought the same thing with the EDS but had already checked. Also, we have 14 different 1768-L45 in here, all in a different cabinet. This was the 1st time I looked at the system on out Ethernet, I could see all but two. The same thing worked on the 2nd cabinet....could only see the Ethernet card, then pulled Flash card, could then see backplane, reinserted card, can still see backplane.
