Cat 5e UTP Question

Hi quick question for the network pro`s
Please correct me if i'm wrong

Cable is already installed to network 2x computers at the moment.
Cat 5e modules and data box's need installing on both ends.

Do i set the cables for both ends as straight through T568A and use a
cross patch cable at one end to the PC and a straight patch at the other
to accomplish this.

More computers are going to be added shortly so thats why i'm not using
a long cross cable from PC to PC

Thanks for any help

 

Even better; if both are recent Ethernet controllers, you can probably
just leave them as 568A straight through. Recent controllers can
recognize and behave as crossover cables.
Let's see, though -- I'm not sure what term you are looking for in the
descriptor...

 

If you're going to be adding more PCs you'll need a hub (or better, a
switch) to network the 3+ PCs. Then you just connect each PC's network
card to a wall RJ-45 port using a straight through cable. The wall
outlets connect back to the switch using cat5e/6 in straight through
config.

OK but will this way of mine work ? Cheers

 

What is a Cat 5e module?

568A or 568B doesn't matter as long as you use a consistent choice all
the way through the wiring (but not necessary). A patch cable is still a
patch cable, the signal functions on the pins are the same only the
color changes around for a few wires.

It either a crossover or a patch cable (implies straight) , not a cross
patch or straight patch.

For 2 PCs, Yes.

PC - patch - wall socket - straight wired - wall socket - crossover - PC

In that case , get a switch / repeater (most autosense and cross the
connection internally, some have a port with a push uplink button to
make a crossover, others have a shared port [1 / 1 crossed] , 2 ,3 ,4 -
you use port 1 or port 1 crossed then ports 2,3 4 as normal) , and use
patch cables throughout. Makes it easier not having to remember 1 cable
is a crossover, or trying to debug a fault and forgetting 1 cable is
different from the others.

So you would end up with ,

3 PCs - switch - patch cable from uplink port - wall socket - straight
wired - wall socket - PC

Since you are planning to add more computers later, just go out and get
an inexpensive switch. Then all you need is stright thru cables from
each computer.

 

I use different colour protectors for A than for B - multicoloured cable =
crossover.

It is convention to make in wall and permanent wiring straight through.
Then when you expand your network you won't have any 'which cable is which'
problems.
Use either A or B as long as both ends are the same (a crossover is A at one
end B at the other)

Thanks for all the info guys - sorted it quite easily with the groups help.

 

Good idea. I never use xovers at home.

For work where it can't be avoided and only standalone test equipment
there the a big tag clipped to the cable - Do not connect to network.

Some times some people pay attention :-(
