Possibly.  Also if I'd had it connected to a decent switch.   If I have a chance I'll set the port back to fixed speed with autonegotiate disabled and see if usable messaging shows up, but I doubt there will be time.  Ditto temporarily plugging it into a Meraki switch port to see what is says.

But while the problem was occurring, we tried the other three NIC ports, all of which had auto negotiation enabled and no hard codes for speed or duplex, and all of them failed the same way as EIA-0 for DECnet, and showed link down on the device.  On two different desktop GbE switches (which are toys, so might be an issue though they worked with HP VMS initially).  I did not plug into one of the Cisco or Meraki switches, though, which might have provided usable diagnostics.  It is entirely possible the desktop switches are nonconforming and perhaps the engineer Robert mentioned has fixed things to the point that those switches are no longer good enough.  In production the server will be connected to Cisco Catalyst switches; I just don't have enough ports here to handle the segregated network that the server, a test alpha, and a monitor/terminal emulator PC is on except by using the desktop switch.
