- In a continuation videos on our home networking series,
today we're going to look at testing our patched leads.
And we're going to test them using our Patch App & Go.
A tester that we've seen in a previous video that
tested from the patch panel of electrical installation
to the data points throughout it
in order to confirm determinations or connections
were correctly laid out.
And this brings me to a questions we keep getting asked.
We keep getting asked,
"Which of the two systems should I use?
Should I use the T568A or
B as our systems?"
So what we're talking about there
is the way we lay out our conductors
in the form of the color layout.
And in truth, it doesn't matter which one you choose.
However, the most common system is to select the B type.
My strong recommendation is confirm the system
being used in installation and continue that one on.
But just bear in mind, the B system is the most common.
So they patch leads themselves
are either crossovers, which is a little bit rarer
than the standard straight-through,
so we'll look at the through ones first.
So what's happening when we say
our lead is a straight-through connection?
So we need to know what's happening at the data plate itself
as well as what is happening
here within the actual switch
or within the actual hub itself.
So a PC will send out it's information from here,
via the patch lead,
it will send out it's information on terminals 1 and 2.
Okay, and it will receive it's information
on terminals 3 and 6.
So that's within here.
It flicks when we think about the switch
or the actual hub itself
so the hub itself will switch,
will send out it's information
on terminals 3 and 6
and receive it's information
on terminals 1 and 2.
So when we're doing our straight-through connection,
that is the reason and thinking behind it.
However, there is an occasional way
you need to make a connection between
PCs or like-devices and in that case,
you're gonna have to have a crossover lead.
So PC number 1 will use terminals 1 and 2
to send out information and 3 and 6 to
receive the information and the opposite flips around
so you'll change your colors around
because at the other end,
you'll have 3 and 6 sending information
on 1 and 2 receiving them.
So in real terms, you'll make one of the ends off using
the A system, and one of the ends off using the B system
in order to get a crossover lidded.
I've got them on the bench.
Let's go to the bench and have a look
at how we're gonna test our leads,
whether we're using the A system or the B system.
I've also got one that's a crossover lead as well.
So in front of me, I've made up three patch leads.
I've made one up with the B method, both ends,
the A method and a crossover
that has B at one end and A at the other end.
How do I know when I pick up a patch lead
or I've made one up that's one on the side
which one's being used?
So simple case of keeping the gold pins up facing you
and you're looking at the left-hand one.
So I'm looking at pin number 1
and in this case, I can clearly see that is white and orange
and I can confirm it on the other one,
again, it is white and orange
meaning that this patch lead is using method B.
Okay, so we got this one here.
So this one's got A.
I've labeled it A both ends.
So when I look at this one,
again, exactly the same principle.
I've got the gold pins at the top
and I'm looking at the left-hand one.
I'm looking for that color
and I can see that is white and green.
Okay, so I can confirm it on both
making this the A-type method.
Works exactly the same with a bolt lead as well.
This one here's got a combination of both
but we'll worry about that in a minute.
But we're gonna set up our Patch App & Go
to test these leads
and to do that, I've gotten to a very famous online seller
and I've bought myself two of these.
These are RJ45 couplers
and this makes it very easy to adapt the kit that was seen
in a previous video in order to take the patch leads so
we're gonna bring the phone in
and get the app opened
and we'll get testing those.
So I brought my mobile device.
I've got the Patch App & Go app opened.
I'm gonna take my dongle out my box.
There's a button on the side
as we've shown you before.
Press and hold that
and we should see it starting to flash.
And you can see now,
it's brought up the fact that the two have found each other.
I've used them before so they're paired together.
So we click on it
and now, we've got the ability to do
multiple tests, quick tests, and trace.
We're gonna be doing a quick test.
So we're gonna press the quick test button
and now we can start using our couplers.
So I said I'll do the B one first.
So these are both B ends.
So let's clip those in like so.
And then, we need to take our dongle into one end,
doesn't matter which end you go in for your dongle,
and then, we need to just get out one of these.
Just smart plugs, again,
it doesn't matter which one of these we choose.
Plug it in like so, okay,
and then, we need to go through the system here.
So we've got cable type,
we're going for category 6.
Shielded, no.
And then, at the top here, which is often missed,
we've got 568A-- it says USA--
and 568B which is Europe
so we're using the B method.
Press the B method
and then, we look down and press the test button.
And you can see it's clear.
So we've got the green light come up on here.
Okay, and a green LED on here
and the test has passed correct.
Okay, so that's fantastic.
So what we need to do now is we wanna check the next one.
Disconnect these.
Okay, like so and move the B lead out the way
and this time, we're gonna use the A lead.
So clip in as we did before
into the actual device itself.
Plug those in.
Back into my app,
we go back to the home button
and now we're looking for, again, quick test.
Exactly the same process again so cable type,
it's 6, shielded, no, and now, we're gonna go for the A.
Press the test button,
LEDs flash,
and it's passed that test as well.
So it's confirmed both of those tests so
really simple by just putting those couplers
on the (mumbles) and you're off and running.
Let's do the A and B one
so this is the crossover.
This might be where we're connecting
between two like devices.
So we're getting rid of that one.
The first thing you choose
whether it be the B or the A end, okay,
so let's choose the fact that we're gonna do
the B end into our actual dongle itself.
And then, into the
smart plug, let's put the A end.
And we go again, so quick trace.
Now, we can't choose one because obviously we got a problem,
there isn't a crossover lead to choose
but we'll choose the right cable.
6, and it isn't shielded
and let's choose it as big
and that will make it the first one.
So let's go over the B test.
Okay, so it's come as a fail for us
but we've got to look at now,
the left and right hand side
so we've gotten white and orange, orange,
white and green, blue, white and blue,
green, white and brown, brown.
And then, when you map it across to the other side.
Actually, that follows the pattern for A
so it's white and green, green,
white and orange, blue,
white and blue, orange,
white and brown, brown.
So actually, by looking at the two sides,
we've actually got that crossover connection done.
So we've confirmed actually by looking at that
and knowing our two patterns,
whether it be the A or the B.
Left hand will be on B, right hand will be an A.
We can see we've got the pattern correct.
So that's a really easy way
by adding just some little couplers here
that you can actually use the Patch App & Go to check your
patch leads for confirmation whether you're using the
B system, which is very common,
the A system, or in this case,
we made up a crossover lead.
So when we look at the back of our Euro module,
we can often see, can't we?
All of those colors and it can become a little bit confusing
if you look very closely in there,
you'll see a A and a B
and it's just a simple case of following through
whether you'll be on the left-hand side
where the A is or the B,
whichever the system, B being the most common,
and follow the pattern down for the four on the left
and then, likewise for the four on the right,
choosing either A or B, with B being the most common.
Remember, these are pairs so it's actually
four pairs within our conductors as we lay those out
and we punch those down
so it's just another little tip for you.
Look for the letter, normally B,
follow it down on either side
in order to get the colors correct
for the actual connection of a Euro module.
So hopefully, you can clearly see
how easy it was, again, to use Patch App & Go
in this time, to test a patch lead.
And hopefully, it's also cleared up
which method you'd like to use.
It's likely to be method B
and by looking at the actual RJ45 with the gold pins up.
We're looking at the left hand or terminal 1,
and if we see that that is white and orange,
we know that we're using method B
and now, we're also a little bit aware
of what is happening between
either the router and the switch
and actually the plate itself
in order to communicate the information.
So as always, any comments for us,
any fix, please leave them below,
and we'll see you on the next video.
