Hi
Ok...I am now going to finish my home network.

My network is going to be ....Router/4 Port Switch with 2 ports going out to 2 different computers and one port going to a NAS. The last port is going to a 8 Port Switch and that 8 Port Switch will run the last 4 computers.

I have my ADSL coming into a Router/4 Port Switch useing pins 4 & 5...I,ve used the Orange...Orange/White just for my own pleasure.

So which pins will I have to use coming in to the Router/Switch ?
In other words which two pins is the Router/4 Port Switch exspecting to recive the imputs from.

Then on the other side of the Router/4 Port Switch...which two pins is the info going to be outputed from each of the 4 ports.

Lastly...same questions but for the 8 Port Switch.

Thanks
Richard

I don't understand your question... But I'll have a go at answering it.

To hook up your computers and the additional switch to your exiting router/switch you simply use RJ45 patch cables.

Only 4 of the 8 wires are used for ethernet but this doesn't matter - you wire these according to TIA568A or TIA568B specs and use the whole 8 wires if you're making your own cables but it's far easier and simpler to just buy premade cables.

The hub / switch to router connection requires 2 pairs of straight through wiring. It doesn't matter what colour you use but wire straight through pins 1,2,3 and 6 (pins 1 and 2 as a pair and pins 3 and 6 as a pair all straight through) or as sbiddle says buy patch cables.

My views (except when I am looking out their windows) are not those of my employer.

Hi
So it is pins 1 and 2 as a pair or pins 3 and 6 as a pair.
I think that is what I needed to find out.
I understand that the colors are unimportant.

I should have mentioned that all the rooms cables are terminated in a 12 port patch panel and althoght I can used std patch cables between the routerr and switch and then use them onto the patch panel.I still need to know which pins I need to terminated the room cables into the patch panel.Sounds like it is 1 and 2 as a pair or pins 3 and 6 as a pair

I also understand that I should have run two Cat5e cables to each room ...one for the phones and one for the network.
But I'm a lasy bstard and I ran one cable to each room and used on pair for the phones and one for the network.
No way I am getting under the house to run more cables.

Will give it a try and see how it goes.
Thanks
Richard

Ethernet requires two pairs (4 wires) to work so you can use the other 4 wires in the Cat-5 for something else but you will need to use 4 wires for the network otherwise it will not work. Phone wiring only needs 2 wires but ethernet needs 4 (2 pair) so you are ok with one ethernet cable as it will carry network on four wires and phone on two wires leaving two spare wires.

I'm still a little confused as to how you're wiring things up.

If you only have a single cable running to each room this needs to be wired from the patch panel to a RJ45 socket in the room. You can then use a voice/data splitter (one at each end) to split that single cable run into both phone and data.

It sounds as though you are only planning on wiring up the wires at each end that you need for ethernet and then wiring the phone seperately. This is awfully messy and virtually guaranteed to start causing you issues.

Colour is important which is why all keystones and patch panels are coloured. It won't impact on performance but it means it's simple to identify wiring and to punch it down - I don't see why you would want to use different colours as all it's going to do is confuse you.

Wikipedia is your friend. :)

http://en.wikipedia.org/wiki/10BASET

If you are wiring a 10 or 100 mbps network, pins 1,2,3,6 are in use.

The colours do matter inasmuch as they have to be a matching pair for longer distances (I believe). I don't think it
will matter for internal house wiring as long as you get the colours the same on both sides. :)

I recommend getting a cable tester. It will cost you ~$50, but it is well worth it saving you hours of frustration.

[Edit] Yes, SBiddle is correct, using the standard will help you keep all the colours correct - pick one and follow it!

My 2c,

You may not care which colours you use for what but, as already stated by others, stick to the standards!
This will help the next person who moves into the house if they ever need to do any rewiring.
It can take a very long time to figure out what's what if someone has wired up CAT5e/CAT6 but not stuck to the one of the standards!

Opinions are my own and not the views of my employer.

Hi
Now thats the info I needed.
Thanks for the link.

I know I should have stuck to the proper colours and as it turns out I can still wire it all up correctly.

I will do a little schematic once I have finished and let you guys pick holes in my wiring.
Thanks
for the help.
Richard

Hi
Here is a drawing of my proposed network.
Any blatant errors?
Is it correct to conect the switch to the router by connecting port 4 to port 8?
Thanks

Correct, depending on the switch and router is whether you need a crossover cable or now to do it. Most now just auto detect and cross for you. Try with a standard Cat5 cable, no luck then use a crossover.
