next up, let's talk about the hardware tools that we're going to use to determine issues with cable or basic connectivity problems.
Here's a list
Clippers are going to connect RJ 45 twisted pair cabling.
You've got your cable tester to verify that it works. Punch down tools for your punch down blocks. A T D. R is a time domain. Reflect a meter
tone generators loop back, multi meter, maybe spectrum analyzer.
First of all, our cranberries,
the way this works is you have a strip twisted pair cabling, and they usually have a little notch where you can put a nick in the cabling so that you can pull off the outer sheeting.
You've got to be really careful, not damage those inner wires, which happens all the time. It means that cable is not going to work.
Once you pull back the outer shielding, you complete your pin out like we saw in earlier chapters, where you pin for maybe straight through cable.
You shove those wires into an RJ 45 put the RJ 45 with the wires in there in the crisper and almost acts like a set of pliers or you pull them together and you hear a little snap. And that's what you know, that you set the wires
whether or not you said it, probably there are no guarantees, which is why we have our friend the cable tester.
These testers can be basic. They can be more elaborate, but in and of themselves, you plug both ends of the cable in,
and I'll let you know if the first end is wired correctly. The second end and will it transmit?
You can have these for optical cables as well.
Here is your punch down tool. This is in some ways a little bit like the idea of a crisper, and that when you're putting your wives into the termination blocks, you need something to pierce through the wire and make sure you're making good connection
to pierce through the sheathing and even of that wire. So the copper wire is getting the connection it needs to patch panel. That's what your punch down tool is going to be for
time. Domain reflected meters TDRS are basically used to detect issues with cable. You can have one for an optical cable or we used to have them for co ax networks because within co ax network, it's really important that both ends of your cable are terminated. If you have a break in the wire anywhere along the way, it could take your whole network down.
We would use a T D R to kind of send out a signal and determine approximately how far away that breaking the signal was
tone generators. Sometimes you have a lot of cables, and sometimes the person that came in behind you didn't label all the cables, and you may have congested cable bundles.
What this probe is going to do is help you determine which connection your cable maps do or help you locate the cable in the connection port.
A loop back addresses 1 27.0 point 0.1,
and that's using software that's making sure you can send and receive, essentially testing the TCP IP commands.
You can also use a hardware loop back adapter to make sure your network card is sending and receiving, and that you have the right connectors. That's your loop back adapter.
A multi meter is called a multimedia because it checks a variety of electrical issues
A lot of times these will do voltage, current and resistance.
You've got certain components on a system.
Devices are a little bit more green friendly today and don't use as much electricity.
But it used to be that you had a components are plugged into your system that would either need five volts or 12 holds, and if they were not supplied with the right amount of power, those devices wouldn't function properly.
It wasn't necessarily they would just all out fail. There would be just some kind of weird results. Maybe over time a hard drive would fail. You'd replace the hard drive. Two months later, that hard drive fails, then another one.
There is such weird issues that you can't always put your finger on. Sometimes it's traced back to the power supply, not out putting them out of voltage That's necessary for your components.
