chevrolux: A newbie isn't going to be able to pick up a couple of tools (of which I say you only need side cutters and a punchdown tool), wire up a link and have it pass on a Fluke tester, but they are certainly going to be able to wire a 20-30m link and get gigabit speeds over it.
Plus if it's something that interests you then just go ahead and do it. There is enough documentation/forums/blogs out there that anyone could go and grab some cable and get their house wired up.
If you screw up drilling holes whole you're at it, that's your problem. Why should anyone else care?
When i first started with data wiring, i took it pretty casual styled. i was taught by a Data electrician so was like yeah, I'm doing it all right. sh!t this is easy.
once i got more into what i was doing, piping vlans poe, and the likes i noticed there was occasional really weird issues with the network. random broadcast swarms and so on. switch interfaces showed a bit of errors...
Testing each link, i was getting full duplex gbit, throughput was what i'd put within the acceptable ballpark.
Pulling out my actual cable testers, it became very obvious where i had screwed up.surprisingly once correcting these issues my network has become extremely rock solid; even down to nolonger getting random esxi crashes...
Long story short, anyone can watch a video, look at a picture online and crimp or terminate a cable.
to actually do it properly and not cause further un-obvious issues down the line, no. they need practice, experience and real quality tools.
