Julie Jacobson writes, "It's so much fun to deride some of the worst home wiring jobs in existence. But once in awhile, we should salute some of the cleanest, most perfectly labeled cabling jobs in U.S. homes. At the recent CEDIA Expo, the association for home-technology integrators handed out awards for the Best Dressed Systems, each featuring miles of cable, hundreds of connectors, tons of steel, and a clean aesthetic that could make the most finicky designer swoon. Show them to your own installer for inspiration."

    Found an old picture of one of the messiest racks I have ever seen. [mtrx.net] Personally I think a messy NOC should be a punishable offense. I can't tell you how many times some stupid blip in the system is caused by a dangling wire with so much other wiring hanging on it that it gets pulled from the panel. Nothing like a 4am pager going off, coming into work and finding the root cause of the problem is the idiots that wired the rack. Kudos to those who do it right.

    ... there is such a thing as carrying it too far. I'm reminded of the tale of the junior sysadmin who proudly showed the senior sysadmin the cabinet he'd just wired up. Very neat, very pretty.

    The senior sysadmin looked at it thoughtfully, then flipped a single switch. Every server in the cabinet went down. Yup: every server had its entire power source coming from a single rail, instead of having the two redundant inputs coming from different rails.

    Where I work [monash.edu.au], every cable to every server in the machine room is labelled at both ends. The patch panels are also labelled with the address of the other end of the cable. Makes troubleshooting network problems a lot simpler (and that's important when you're talking over 200 servers on the floor ...)
    • To a limited extent, I agree.

      Neatness is one thing, but those examples just look like an advertising photo for nylon wire ties. I mean, they look nice now, but what happens when you need to move one of those connections around, say from one port to another?

      You'd have to cut 50 different ties, and all the wires are cut to such precise lengths, you'd probably end up having to splice some sort of nasty extender in there (adding a significant insertion loss due to the connectors or splice). It would be a total mess. Having everything wired in drum-tight may look nice, but it's a bitch later on. Something that has more "drip loops" before all the wires get bundled up into single harnesses may not look quite as polished initially, but it's far easier to work on down the road.

      I've worked on audio systems like this, and it always strikes me as something that you'd do if you were a contractor working on a one-shot job, something where you want to impress the client and justify your fee, with no real thought to maintenance later.

        That's exactly what I was thinking while looking at those pictures.

        Half of the purpose of having neat wiring is maintainability (in addition to aesthetics, air flow, and just plain keeping crap out of the way of other things). That setup is almost as unmaintainable as a wall draped in spaghetti. I at least hope they either have good documentation kept up to date to match the small fortune and abundant time they spent on zip-ties or else have both ends of their cables labeled so they know which cable to yank once they do cut all those zip ties, because you aren't going to trace those out by hand.

        I guess if your system is perfect and you have no need to ever replace equipment or expand, this is fine, but for the rest of us, give us some service loops and removable wire clips.

    A super-neat wiring rack is great, if you don't need to get to the wires often. If you need to rearrange wiring often (for whatever reason), there is no point in making it look great (though a certain level of neatness is required for optimum efficiency).
    • Exactly. Neat-looking network and server racks are for taking photos for glossy magazine and sales brochure covers. In a *real* IT shop, like the ones I run, things can change on a daily basis... sometimes several times each workday. We keep our racks just neat enough to be serviceable and flexible for the rapid config changes and equipment installs and removals we perform very frequently.
    • That's definitely a problem. Bundling all the wires together so tightly, with no slack, allows for no rearrangement and might not allow equipment substitution. It shouldn't be a rat's nest, but I don't think making it look like it was moulded in place makes it easier. Ideally, it should be neat, but making it accessible and easily changeable is more important.

    Back in the days when RS-232C ruled, I was in charge of wiring, and our department always made fun of another department's propensity at overspending and buying expensive gadgets.

    When they wired their mainframe, they spent about $2000 for a bunch of bix panels.

    When it was my turn to do the same job, I took $5.00 and went to the hardware store, I picked up a 1ft by 4fr plywood scrap and bought a box of finishing nails and brought that in the office (the canadian head-office of a fortune 500 company, btw) and started hammering away neat rows of nails to which I soldered wires from a 100 pair cable we ran between two floors.

    On hearing the hammering, the boss of the other department (who happenned to pass by by chance) came to have a peek, and he sees me hammering and soldering and asks me "what are you doing???"

    - I'm doing a patchboard for the serial lines.

    - Why don't you use a BIX board like we did in the plant?

    - Because yours cost $2000 and mine only $5.00.

      Twenty years I worked in telecom in Toronto (ROLM, Mitel, Nortel, others), and if I had ever seen a punch down block where the tech had soldered the connections, I would have been astounded to the point where I would have walked out. There's a reason for BIX blocks; they work well, they keep the MDF reasonably uncluttered, and more important, you save thousands in the long run through easier maintenance and upgrades.

      Your solution is the perfect example of "penny wise, pound foolish".

    I'd actually argue that although some of the wire racks pictured look nice they're unusable - you'd have to snip all of those zip-ties to trace a cable. If letting the cable lie in the wire management isn't good enough Velcro would be better, and less likely to be over tightened to the point of pulling the cat5 twists out of spec.

    In our computer room I just provide plenty of wire management, a wide assortment of cable lengths, and a picture of the wedgie I gave the last admin who kludged something 'for testing' and left it that way for months.

      Exactly, you need to be able to get to any cable. Zip ties are single use. Velcro rip ties, while more expensive, are reusuable.

      And talk about overkill on that one 24 port switch or whatever it was. They used at least 24 zip ties, one for each cable and some doubles. Don't you think one every 2-4 would have done just as good a job? Instead, they completely locked down the cable making any troubleshooting a nightmare. Three well placed ripties would do a fine job, keep it orderly AND maintainable. Especially if the ties were long enough to have additional room for growth.

When I worked for a big A/V firm out of OKCity, our service techs would tear installers a new hole for not leaving some sort of service loop (usually at least 6", preferably 12") on every connection inside of a rack. We eventually started using deep well Panduit inside of the equipment racks: It leaves the rack looking nice, yet gives you a place to shove a service loop that's out of sight.

          It is hard sometimes to make service loops look neat, but they're absolutely worth any clutter they cause.

          Of course, with a little creativity it's often possible to bundle everything up so that one or two snips releases plenty of extra length.

          My "favorite" though is people who pull fibre cables "nice and tight" then zip them within an inch of their lives while the equipment is warm. As soon as it's powered off for a few hours, fibres start breaking. It sure looks pretty until you have to cut a zillion ties to do anything.

  • If I were building a house, I would almost certainly do the low-voltage wiring myself. Is there any reason not to?
    • you could do the high voltage wiring yourself too. i've done lots of stuff with digital and analog circuits, and they nearly always have to be debugged. but once you know that black is hot and white is neutral and bare copper is ground, it's very rare to wire something at 120 volts and not have it do exactly as expected. dual-switched lights are the only exception to this rule, but only in cases where you're faced with someone else's existing work.
      • Right, but if it doesn't do exactly what you expected, its a bit more serious if its 120V! Besides, it is illegal, unless you are a qualified electrician and have passed the wiring rules. Or at least this is true where I live, surely it is true in USA as well?!?
  • Wow, I'm impressed. I run a fairly cable intensive home network, and I get grief from friends & partner for my neat cabling obsession. But once you've tripped over the wires running from your video card to your TV going for a piss at 4am, and chip a tooth when your mouth hits the arm of a chair on the way down, you get neat.

    You want to know what I didn't see in a single one of those "neat & tidy" wiring photos? I didn't see a single service loop. Sure, anybody can wire-tie the heck out of something and make it look nice and neat on project completion day. Hell, I used to produce racks of similar tidiness when I was 19, working for a regional communications installer doing hospital and school networks. But it takes a real artisan to make something look that neat AND design it to stand up to five years of corporate changes and rearrangements. Just wait until one of your wires has to move from the top of the rack (near the entry point) to the bottom of the rack.

    I didn't Read either of TFA, because they seem to be slashdotted at the moment.

    However, after years and years of living, I can tell you that "if a job is worth doing, it is worth doing well" is just not true. Sometimes doing a job "good enough" is more than enough. It might get torn down next week. If you wash the windows "OK", that is probably good enough, they'll be dirty again soon enough.

      You're totally right. That's something I've learned at my new job. I was always trying to do things perfectly, and I realized that it took too long to do them as well as I wanted, and even then they wouldn't be *perfect*. I thought back to my metals class when my teacher talked about the level of accuracy which is necessary for particular jobs, and how you wouldn't build a house while measuring lengths in micrometers just as you wouldn't build an engine while measuring in inches. (I forget the name of the principle, I was in Jr. High.)

      What really drove that point home was when somebody plugged an ethernet switch into itself a few weeks after I'd done a moderately good wiring job in our closet and I had to tear it all out because I couldn't even get to our management console on the switch to see which port was causing the traffic storm. (Netgear FSM750S if you want to know.) So, just as many people had pointed out, my zip-tied bundle of cables did me no good and they are now hanging off the side of the switch in a mess, no longer matched up to the numbers on the patch panel.

      I guess it really does matter what kind of job you're doing... If you're not going to be changing anything, zip tying it all up might make sense. They staple AC wires inside the walls of houses, so I'm sure we can find an instance where zipping up cables would be appropriate. For me though, I'll take velcro and a slight mess.

    The discussions of maintainability reminded me of a funny story.

    At the first company I started, we had an excellent ops fellow who did all our wiring. The racks were immaculate, on par with the the winners in the competition. We never found maintainability a major factor, as things were wired right, and patch panels routed things as changes dictated.

    However, on one occasion, I do remember his obsessive compulsive approach annoying. We were doing some moving around, so he was coming in and out of my office every few minutes for various changes, as was I. I typically don't screw in my monitor (or other cables), because, well, I don't need to, and I often change things around. Anyhow, the work I was doing that day involved plugging the monitor into a few different units to check things out. At one point, I couldn't remove it from the PC. It had been screwed in. I undid it, and moved it to the next PC I was checking, went to the bathroom. When I came back, I couldn't remove it, it had been screwed in again. Every time my employee walked by, he was screwing the monitor cable in tight, the way it "should be." This went on for about four or five times. The fact he even spotted it was amazing, much less the inability to walk by it without "fixing" it.
