RE: Running out of twinax consoles...

I'm no advocate for twinax but we never have had a problem with twinax
console connectivity. Our first foray into Cat 5 with twinax had a few
issues with distance. We switched vendors (hubs and baluns) and hardly
ever had an issue.

However, we are mostly HMC here. I still have two twinax consoles but
that is only because we keep on forgetting to swap them out. I have had
the HMC/SP puke it's guts one night but other than that I like the
HMC....and remote access is pretty cool......

In over 20+ years at two different jobs I can count on one hand the
times a
twin-ax console went out. We never had a wiring problem or balun problem
or
port 0 problem. We were aware of the device type issue but all we had
was
the one model anyway. At my last job the entire Computer Room was on a
huge
UPS so we did have conditioned power to EVERYTHING in the room so that
might
have helped. Sound like you've had a lot of bad luck (?)

And there was even the one time when one failed, putting the replacement
in
picked right back up where the other one had been in an upgrade !

You obviously didn't go through the plethora of broken switches on
3196's
that I did.
Or the twinax going out on your box - Just port 0, rest worked fine (no,

it was not wiring or anything.)
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.
Now you can get into the myriad of problems caused by faulty twinax
cable
ends, balun wiring, maxxed out number of splices, etc dealing with
twinax
wiring.
