    I know I may post here wrongly but please bear with me, because I don't know where else I can get help.

    My question is how to make a Giga Ethernet network wiring. I know from Internet there are diagrams for cable but I want to know the wiring of the module (the plastic box that I insert the LAN cable.

    I house has a "CAT 5" cable laid, but it is only "half connected" because I found there are 4 wires unconnected. This is what the wiring when view from the rear (with the notch at the bottom).

    Green -
    White -
    - Orange
    - White

    The 4 wires unconnected are (blue,white) and (orange white). The colors inside () means they are twisted pair.

    So in order I can use Giga Ethernet, how should I wire the unconnected wires?

    My 2nd question is is the wring symmetrical? The above module is what I see at A end of my house, so I wonder if the B end is the same?

    My 3rd question is should I make a straight or crossed cable? The A end is to be connected to a Giga Ethernet Switch, where the B end is connected to an AIrport Extreme via a LAN cable

    Thank you very much.

    Follow this link,

    and crimp the cables for 568-B format shown in the website. theoretically, you 'need' CAT5e or better for gig-ether.

    regarding questions 2 and 3, crimp both ends the same 568-B (this is straight-thru) for your computers to communicate with your switch/router.

    if you want a crossover cable, then crimp one end 568-A and the other 568-B. crossovers allow you to connect similiar devices (such as two switches that do not auto-mdx) or two computers directly with each other.

    Thanks but I am still not very clear.

    The cable is used to provided a 100M connectivity and it is working.

    As Airort Extrem supports Giga Ethernet connectivity, I would like upgrade the connection by wiring the remaining 4 wires.

    Do you know how to deduce the pin assignment?

    I mean, viewing the rear of the punch down module is like this:

    Green X
    White X
    X Orange
    X White

    Where X means no wire. The colors denote the twisted pair e.g. Green and While are twisted pair.

    If I can know which pin is 1, which pin is 2 etc., then may be I can punch the remaining wires to make the module 1000M.

    Thanks again.

    1 white and orange
    2 orange
    3 white and green
    4 blue
    5 white and blue
    6 green
    7 white and brown
    8 brown

    and please learn to use google, you could find this answer out yourself in about 30 seconds, instead of having to ask people over and over to spoon feed you the information.
    enjoy the challenge of finding an answer, and the feeling of satisfaction that you get from figuring it out yourself. or you could just continue to hope people help you along.

    WAW 74,

    Sorry I think you misunderstood me.

    I know the PIN assignment is available but all from a cable / jack perspective. I want to know from a module perspective.

    For example, the diagram I showed maybe

    1 2
    3 4
    5 6
    7 8


    1 5
    2 6
    3 7
    4 8

    or other combination.

    The module itself does not have the numbers shown. I try to search by typing AMP Enhanced CAT 5 wiring (as the module only indicate AMP Enhanced CAT 5) but did not get what I want

    Thanks for your link. My module show something similar but I have 4 "horizontal rows" instead of 2.

    I was hoping someone may have experience with the module that I am using (I did not buy myself, it was already laid when I bought my house). I did not meant to bother you guys.

    I assume you mean the 8P8C Female connector located in the wall, and exposed for the patch cable to connect.

    They usually have a wiring guide on them (sticker), and it's by color code. Odd your's doesn't. :confused: Unfortunately, I did do a search, and couldn't locate what you want. :(

    Ultimately, you only need to make a 1:1 pinout match with the wiring. :eek: ;) Where ever you locate the wiring on one, it needs to be replicated on the other end. (This keeps the signals in the correct locations at least).

    If I do find what you want, I'll post. I might be able to locate a camera and take a pic of the module for you. Provided I can get a good shot of it to post.

    I found the installation instructions in .pdf format.

    This should be what you need. :)

    Thank so much all for your help. I am excited to get the GigaLAN running.

    The modules are easy to install, and should go quite easily. :cool:

    I finished my 1G Ethernet & satellite installation (home) 2 weeks ago, and just finished the last voice line yesterday. ;)

    Good Luck. :D
