Heavy-handedness?

Or the twinax going out on your box - Just port 0, rest worked fine (no,
it was not wiring or anything.)

How is that different from a network card or a card slot giving up the ghost? At least you still had the remaining ports available so most users were able to access the system.

Or that QAUTOCRT is a joke. Test that by renaming CRTDEVDSP, swapping out
the system console from one model to another (like, from a 3180 to a 3197,
because yet another system console died) and finding out that you have no
system console.

That's hardly the fault of QAUTCRT. It does what it says-- automatically creates devices. It's hardly the system's fault you did a stupid thing. OK, they could have called the underlying CPP (or a more direct program) but using the command makes things so much easier.

Now you can get into the myriad of problems caused by faulty twinax cable
ends,

Not on manufactured cables--only on in-house or home-made cables. Or again, heavy-handedness when lining up and joining the pins.

balun wiring,

That whole concept was flawed--driven solely by cheapness. Powered hubs were usually fine but using un-powered led to a heap of problems. Besides using Baluns is not really twin-ax. You have Twin- ax at the start (host end) and Twin-ax at the end (terminal) but what's in between sure ain't Twin-ax.

maxxed out number of splices,

Yes, so buy new cable and use long runs instead of stringing together a bunch of short cables and hoping the signal gets through.

etc dealing with twinax wiring.

Most of your described problems are not directly related to Twin-ax itself but rather to a particularly poor site implementation of it.

Simon Coulter.
