in my opinion: do not underestimate the compression connector and its catch mechanism
in my experience (with MENET ): the wrong catch mechanism did the difference between " properly working " and " not properly working "

This sounds (from the view of a small child's picture made during class-time) like your problem?  That's not a lot but maybe, different slot, and extra push BEFORE engaging locking?  I'm grasping here....

Oh boy.

I don't see how the compression connector latch (catch mechanism?) could cause this, but filthy or damaged compression connectors certainly can. Also, when installing a new option in an Octane, you have to beware of the dust that accumulates in the system after all these years. If there's dirt on the backplane PCB where it mates to the compression connector, it will end up in the compression connector. I've learned this the hard way when installing a PCI shoebox in my Octane. It never worked reliably until I tore down the system, cleaned the surfaces where the compression connectors mate, replaced the compression connector of the shoebox, and re-assembled everything.

The ethernet and serial functions of the MENET card share a PCI bus on the card, with a single PCI-XTALK 'bridge' upstream. If there's an 'upstream' problem like dirty compression connector, or blown PCI-XTALK (happened to me, crater in the chip!), you'd expect either all PCI functions (serial, ethernet) to either work or not work. Not half of them.
