Home Network

Hi All,

An electrician wired my house for a network but then fecked off to Oz before Eircom got around to connecting me and he never finished the job.

There are LAN sockets in all the room and they are all wired back to 1 room. They are not terminated at that end. I tried puttin a plug on that end and connecting it directly to the router (i.e. not using a socket & cable) but it didn't work.

Before I blame the wires or something else i just wanted to check that I should wire the plug the same as if I were making a network cable.



The socket seems to be wired correctly.

Many Thanks

Al

Hey, found this. Hopefully it'll be of some help!

Looking at that I think I need to wire the plug as a crossover cable.

I'll give it a try tonight

Thanks.

There are two networking standards T-568A & T-568B.
T-568B is always used by anybody that knows how to wire ethernet up properly.
But sometimes electrician will wire them up with the T-568A standard.

You can check this by opening up the finished socket in the room to see which standard he used. If he used T-568B, you use the image that you have attached. If he used T-568A, then you use the crossover connection.

You will also need a cable tester to check if the connections are done right.

That should be correct.

Direct cable is used for example if you need to connect two computers directly together etc.

The quote is untrue.

Crossover cables are used to connect two computer directly together.
Direct cables are used when you use networking equipment such as a switch, router etc.

Not being funny here but I suggest you yank the cables out of one of the sockets and investigate the order in which the cables are terminated. Just in case it is done differentely / wrong - I have wasted hours in the past only to find that cables set up by other people were terminated incorrectly (unlikely if he is a qualified electrician but we have all come across cowboys)

One would need to see the situation first hand to give professional advice but you may need to terminate the connections in reverse if you are not going through a patch panel but directly to a switch.

From my experience most electricians have no idea how to connect them, most still loop cat5 from room to room
