Jeff,
I work with Computone corporation and we manufacture a terminal server that
is capable of 64 ports that can manage all that equipment via console ports.
You can use Linux and some of our software to interface with the terminal
server that will give you 64 tty devices in /dev on the linux box. Minicom
can then open these devices. Or you can skip the terminal server and use
one of our Gold 8 cards or even 4 of them. That will give you a total of 32
ports. Then you can use minicom. Either which way you go it works great
and I'm sure you know Louie Zamora. He can help you configure any equipment
you want. I can help you in the Linux environment with the Gold Cards.
Any questions call louie at 770-625-1653

Oh gosh, yes!
I looked into this very sort of thing at my previous employer - not just
switches/hubs but outboard RAID controllers, Bay Networks WAN nodes,
MicroVAXen, and UPSses.
You may have to pay close attention to your cabling, but you can take this
as far as you feel like by adding multiport serial cards such as those made
by Cyclades. You can co-locate the Linux machine with your switches and
either telnet or X to it (use ssh if you are on a "hostile network;" you
don't want some jerk capturing your passwords.
What I envisioned doing was setting up the Linux box with fvwm such that
when you logged on a bunch of Minicom instances would start and arrange
themselves on the display.
I did get so far as to wire a Linux box up to a big data-center-grade UPS
and I was able to communicate with it using Minicom.
Incidentally, I was using an IBM PS/2 300GL of a sort I've seen in doctor's
offices and behind the counters of restaurants all over town. I found that
they did not work well under Win95 OR Win98 - crashy, flickery video, flaky
networking - but under Linux it was quite well-behaved and I could use its
highest video resolutions with no flicker.
