Video Description

The Crimper and an introduction to the punch down tool This lesson continues discussing the use of appropriate hardware tools to troubleshoot network productivity. This lesson focuses on the following tools:

  • Crimper: used for cable termination, but it can also be used to cut and strip cables. Crimpers can be used on Ethernet, coaxial and fiber cables. Crimpers can also correct terminating ends and wire sequence. When setting up and crimping a cable, leave as little excess as possible outside the connector as that can cause interference.
  • Punch down tool: can terminate connection into a block or patch panel or a keystone. When using this tool, be careful of the blade size and the cutting edge as different size tools are meant for different size cables.

Video Transcription

00:04
So our next tool is going to be our Quimper tool Now are crimping Tool is primarily for, uh,
00:10
cable termination actually taking cable and crimping the end on. But we also have
00:16
tools on here that we can use for cable cutting as well a stripping the outer sheath off of a cable so that we can get to the internal wires now a cable crimp Ercan be used for Ethernet co axel fiber. Essentially, we have different types of crimp er's for different types of cable.
00:32
But we're gonna use the crimp er essentially to take that in connector
00:36
and connect it onto our cable securely so that we terminate the cave when we can use it to connect into a device.
00:42
Now, this is an Ethernet. This is an Ethernet Quimper.
00:46
We're gonna go ahead and we're gonna take this cable that if you watched our segment just a second ago on our on our cable tester, we determine that this cable is faulty. The led is didn't light up correctly. There's something wrong with the cable pronounce from one side to the other. So we're gonna cut this cable open. We're gonna
01:03
aligned some of them were gonna line the wires, and we're gonna re crimp it.
01:07
But we need to make sure that we have the correct terminating ends, the connect, the correct type of connector for our cable and that we have the correct wire sequence.
01:15
So
01:17
our first that
01:19
for redoing this cable end
01:21
is actually selecting our end, Of course.
01:25
And we're gonna go ahead and we're gonna cut the cable
01:27
right at our end. Go ahead and just take that.
01:30
You cut that right off.
01:34
So now that we now we have one end and a flat end, we actually need to go ahead. And we need to get to this internal sheathing
01:42
now. Fortunately for us,
01:47
this cable cutter has two blades, and one of the blades actually cuts through the cable, and the other actually cuts the sheathing for us.
01:55
Let's go ahead and give ourselves a little bit more room to make it a little bit easier toe
01:59
demonstrate everything we have going on.
02:06
Let's go ahead and open that up.
02:08
So let's go and take a look and let's see if we can re crimp our cable. So we had our fault to cable here, and we went ahead and we cut off one of the ends,
02:17
and now we're gonna go ahead and we're gonna split into our out of jacket.
02:23
Essentially, what we're doing is we're removing this outer
02:27
jacket layer, but we have to be careful because we don't want to pierce
02:30
these inner wires because these inner wires, we only want to pierce them at the end when we're actually piercing them with our connector.
02:38
Any other piercings could cause
02:39
some shorts and some
02:42
Malka neck shins.
02:44
So now that we have our cable open,
02:46
we get a hold of this
02:49
string here,
02:51
cut that out of the way, make it a little bit easier for us.
03:00
We're gonna go ahead and open up our bundles of
03:05
wires here.
03:07
And remember, this is
03:08
unshielded twisted pair.
03:10
So are small wires inside. We have eight of them
03:15
are twisted together, so we have to go ahead and first on twist them.
03:20
We've got them on twisted.
03:22
We'll give ourselves a little bit more room to work with here
03:25
with our outer jacket
03:29
out of the way.
03:32
Now, when you're setting up in your crimping your cable,
03:37
you want to leave
03:38
as little excess
03:42
when you crimp your cable.
03:43
As you can see here
03:45
as little of these cables untwist ID and outside of their jacket
03:50
past the end of this connector
03:52
because that can cause some interference from some electromagnetic interference. Remember, R E m I.
03:59
But we're gonna do a lot here just for our personally our demonstration purposes.
04:04
So once we have our cables
04:08
on twisted,
04:11
we're gonna go ahead and get an even height on all of them
04:15
by lining them up.
04:16
I'm just trimming a little bit off the top
04:19
with our sisters
04:25
so that now we have an even alignment on all of them.
04:31
Then we're going to go ahead and we're gonna choose our color scheme.
04:45
Um,
04:46
there are a or B color scheme which we did way talked about in our earlier module.
04:53
We talked a little bit more about our categories of cables,
04:57
so we need to make sure that our cables are aligned properly, depending on what type of cable that they are.
05:01
These are gonna be a straight through with the other side of our cable sequence.
05:06
Once we have all of our cables a line in the order that we want them to go.
05:13
We're gonna go ahead and get our in connector.
05:15
And in our r j 45 in connector. We have several different channels in here that we feed our cables into.
05:23
So go ahead and we will feed those in there
05:27
making sure we only have one cable
05:30
per channel.
05:31
Okay, Excellent.
05:34
And as you can see, we have no of We have none of the wires exposed past the end of the connector. We only have the jacket,
05:44
and our cables are all fed into. The channels Will take a look at the side, inspect and make sure that all the cables
05:50
touch the end of our connector
05:54
end of our plastic connector so that they're pierced by the little vampire teeth.
06:00
Then we'll go ahead and we will feed
06:05
our connector into the crisper.
06:12
Go, hon. Crimp it,
06:15
Huh?
06:16
So now we've pushed in all of our pins and they've pierced the outer shells of the individual wires.
06:25
We can't pull the end off. We tried hard enough. We probably could, but we We can't take this end off and reuse it. The teeth of them have been activated, and the creeper has done its job. So
06:35
That's our cable Quimper. That's how we terminate our connections into our into our in connectors and how we take our cables and we will take our standard cable. And we make our own length of cable for whatever we want and whatever wiring pin out that we want.
06:51
So now that we've talked about our cable Crimp er's, we need to talk about another way that we can terminate our cables and this is going to be with our punch down tool. Now our punch down tool is going to be able to terminate a cable into a block or into a patch panel or into a keystone, which is what we're going to do here.
07:09
So we need to be a rare of the blade size and the cutting edge of the different blade sizes may equate to are different types of blocks if you take a look at this blade size, if you could see closely, it has won 10 on it 110 which means it's meant for 1 10 block size
07:28
size ports.
07:30
We're gonna go ahead and take our cable here
07:32
and we are going to punch it down into this, which is called our keystone. This is essentially something that you would use, like for Wild Jack. You place this into our wall port, are we'd actually punch down arcade. We drop our cable through a wall,
07:46
punch down our cables into our keystone, and then lock our keystone into our wall face plate and then install in our wall.
07:54
Now our punch down tour. We also said that we have We have a cutting edge. This sharp edge right here is actually our cutting edge. So we want to make sure that this cutting edge isn't facing where our data is traveling. Also, we're gonna cut off our data. We want our cutting edge to be facing towards the excess of our wire.
08:13
So let's go ahead and take a look at down at our table, and we're gonna go ahead and punch down our cable
