THhis is probably a dumb question but I haven't seen it
in a faq....

If I want to connect two 10BaseT hubs together should
the cable be straight through or should it be crossover?
I would think crossover but....

So my situation is:

computer1<---> hub1 <---> Computer 2
|
|
computer4<---> hub2<---> computer 3

and I need to know if hub1<-->hub2 should use crossover cable.
TIA!

You will probably need to use a cross-over cable.

It should be in the Cabling FAQ, posted regularly here in the
comp.dcom.cabling ng.

The hub may have a MDI/MDIX jack, in which case you connect them
together with a straight through cable, and on one hub, you push the
recessed MDI/MDIX switch to get a link lite.

If you don't have such a jack, then you should use a crossover adapter
with regular straight through cables. I recommend against crossover
cables, because they cause confusion. Like if you go to replace it,
chances are that you will replace it with a straight through cable, and
of course it won't swork, so you think there's a problem somewhere else
(i.e. another hour or two wasted). Or if the cable gets taken out and
used somewhere else, chances are that it will cause a problem because of
it not being the standard straight through cable. Crossover cables can
cause real problems if they're not clearly marked as such.

Look at the hub, some of them require crossover cables and some dont. If you
need "pinouts" look at www.siemon.com and you will find some info. If you
dont find it look at www.cablage.com and we will help you.
