No problems on the questions, bud. That's what we're here for. You've
certainly helped us out once or twice, so it's time to return the
favor…
Not totally sure on the answer on advantages of 10BaseT vs coax except
that the twisted pair stuff is real easy to run and terminate. I got
a slick crimping tool that cuts the wire, measures and strips the
outer jacket off, aligns the wires (4 pairs), and crimps the RJ45
connector. Takes seconds to do. Coax does have a maximum length
advantage, I think, but I can't remember what it is. But you have to
be more careful about running it near power cables etc. and how sharp
you bend it. Theoretically, you can use existing phone lines to
network via 10BaseT, but I've never tried it.
The cable closet and punch down blocks are a luxury, I believe. I
don't have one, all my wiring is hidden under the floor, and I hid my
hubs under a return arm of one of my stations. I suppose if I was
gonna do 40+ stations, I'd investigate these items. Be aware that if
you lose power on the hubs, you can't communicate on the net, so put
them on a UPS too, if you can. They draw almost no power. Our hubs
were only about $700 to do 12 stations.
On the other questions: I run all software from the server. My lab is
very bulletproof, and I have a standard setup for each machine, which
I can restore in a matter of seconds. The only thing I have on the
local drives is the Windows INI files and the permanant swap file,
and the INI and CFG files for AutoCAD. Be sure to configure AutoCAD
to place it's temporary files locally, too.
Yes, if you want to run AutoCAD from the server, you need to get an
authorization code for the number of nodes you need. But it does seem
to run quite well.
Can't help you on the network access to modems. I have all my printers
and plotters connected to the server directly (2 parallel and 4
serial ports!). I just took delivery of a HP LJ 4M printer yesterday,
which I may get a JetDirect card for. Depends on the performance of
the existing setup, via parallel from the server.
Hope this is helpful. Keep us posted on progress…
