Make sure it's nailed down as to what you're after.

 

 

 

Plenty of sparkies can and will do a great job with data.

 

 

 

More can do a great job, but will do an OK job because they don't carry the parts, don't want the hassle, and they bid for low cost. This is where you'll mostly find the plugs and the Cat5e.

 

 

 

Some just don't have a clue.

 

 

 

It's also worth noting that they do make fully certified plugs for solid cable that are reliable, e.g. this from Belden. But they're bulky and expensive. The manufacturers are saying people are starting to use them for things like IP cameras, WAPs etc. where the device is fixed and it doesn't really make sense to have a box and faceplate next to it or in the ceiling. You also see them used for industrial ethernet.

 

 

This is interesting product to know about.

 

We had a network installer come and do some repair work on the one above install. There are two cables terminated with site installed clear plastic RJ45 plugs going into the cabinet for exterior cameras. The installer didn't install the cables onto the patch panel, because there weren't any remaining ports on the patch panel.  So there are RJ45 plugs on each end of the cable.  After the network installer tested the previous installers work, he discovered that 1 out of the 4 RJ45 plugs was wiring incorrectly. The network guy said it was an easy mistake to make, because the wires can cross when they are installed. But it showed that the original installer didn't test their work.

 

I would also make sure they fully test the network with a continuity tester at each end of the plug, and also make sure thy label them all correctly. We still have one port on the patch panel, which is wired up, but where we don't know exactly where the other end of the cable goes.

 

Next time I am going to do much of it myself so I can then  be sure it is all done properly.

 

Continuity testers are better than nothing. But for large numbers of outlets in commercial installations where you're aiming for the 20-30 year warranties, they want full compliance testing on every cable. For example, if the cable is kinked midway, or there's too much untwisted length causing crosstalk. This generally doesn't matter so much in domestic.

No disrespect meant to Sparkies but my advice based on much experience... is get an IT Tech to do the cabling and installation.

Hi, not an IT Tech but a Data cabler that is trained in data cabling and will have undertaken training with a data cable vendor (ie Tyco, Simeon, 3M, Molex etc) and has current validation from one of those vendors.

 

Some IT Techs that specialise in Networking may also have such training. Whilst Data cabling is not a controlled trade in NZ like electricians and plumbers it is in many other countries.

 

Edit: some electriciains also have understaken vendor data cabling training, but sadly these are far and few. A few years back when the TCF rules came out for modern structured cabling homes I offered to my local wholesaler to do a 2hr basic course for sparkies, basically they put on a barbie and beers and I give a couple of hours free training on the basics, sadly no one was interested, pissed me off to be honest.

Well I'm not exactly Cisco - just a self employed Field Eng with my own (rural) clients.  

 

What I see often going in after Sparkies, or (God forbid) Sky Installers, is lack of basic common sense: unlabelled patch cables (my #1 peet peev), copper & electrical cable together in same conduit, cupboards with power points either missing or turned the wrong way, tight bends, precut cables with ~10m of excess length looped around nails  and more.

 

About 2yrs ago I started taking photos. If GZ ever has a Network Installation Vault of Fail thread, I'm fully prepared. :)

Heh, that's policy at my employer. Mostly because incorrect labels are much worse than no labels, and having none makes people check first. Patch cables are easily unplugged, moved, plugged, etc. Labeling is for permanent installation like the patch panel itself.

Here's how the data cabinet looks at the moment.  Still a little tweaking needed.

Is that for just behind  the TV/ entertainment unit?. Or are you doing a network cabinet box in that location?

I found that just numbering them helps, so there is a unique number for each end of the patch cable. Easier then to trace between the two.  Because our electrician cut the patch leads too short, it mean that the patch panel cables are not grouped per room and in any order, so there are randomly all over the patch panel, which is a PITA to manage. Have to both number them, and say with room they are in on the patch panel. But I have it to the stage were it is now easy to understand.

That's the (soon to be) data cabinet.  So it's mostly all Cat6 from around the house and also the hybrid cable from the (soon to be) ETP.

Did you decide not to have the data cabinet recessed into the wall? Would be neater if not too late / the wall design allows for it.

Nah, there's going to be some wooden cabinetry in there first.  So a a cupboard and fixed desk.  Then the data cabinet will go in the bottom of that cupboard.  So all hidden away.

Room usages change. Put the same number on both ends.

Well, the cabinet makers and sparkies have been busy and the patch panel, data cabinet etc are pretty much done.  But...

 

It's huge!  I might have to have a word to the sparkies about maybe swapping for something a bit more appropriate.

Hi there

 

Looking good. I would be keeping the size as you will be amazed what you end up in there once you get started. For example do you have a UPS or NAS etc.?

 

Also have think about ventilation too....this will depend on what you pout in the rack.
