In this video, explore punchdown blocks, one of the key elements in structured cabling.
- What's kind of interesting in the networking world,…is that the only time we use little RJ-45 crimps…is for patch cables.…Pretty much all the rest of the time,…we use a totally different type…of connector called a 110-punchdown.…Now, what I have here is a patch panel and I've also got…a little jack that goes to a wall outlet.…And if we take a look at these, we're going to see…that we don't use crimps we use 110-punchdowns.…Let me show you what I mean.…So, welcome to your first 110-punchdown.…This is the back of my patch panel…and this is a 24 port patch panel.…
There's 24 connectors on the front…so there's 24 and each one is numbered…110-punchdowns that correspond to each one…of the RJ-45's on the front of this guy.…Now there's a couple of things I want to bring…to your attention. First of all, notice that…there's a CAT rating to the patch panel.…Everything in the networking world has a CAT rating.…So it's not just cables. Patch panels, crimps,…Connectors..everything has a CAT rating to it and you want…to make sure that that CAT rating matches up…
