How a Wiring Rack Should Look

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."

Neatness is good, but ...

... 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, 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 ...)

Neat != Usable

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.

Looks good ONCE, and only once.

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.
