The biggest clue is that there's no status light appearing on the Ethernet switch to indicate cable connectivity with the GC's LAN card. I've tried switching out cables and switches, but no matter what I do, the lights don't come up. If I load up the 'Diagnostics' menu on the 6890N, it says something like 'LAN not installed' or similar.
Now, all of this is pointing to a main board/network fault at the GC end. The MSD comes up just fine, however. Straightforward thing to do would be to go to Agilent and get a quote for a replacement main board.
However, this instrument is pretty old and only gets used for running basically neat products, so the cost to fix may be too much to keep it in service. I do have a 6890N in my own stash which I could pilfer the main board from, but I'm trying to avoid doing that because I want to get that instrument running at some point.
Is there anything that I might be overlooking, like a DIP switch or menu option or something that might activate/deactivate the LAN board on the GC? Trying to keep this instrument going because it is useful every so often.
