    I think cable ties [wikipedia.org] are a great way to reduce the chaos in a pile of spaghetti-style cables.

    Some people dislike them, but I think they are just not accustomed to using them. Proper use of cable ties means you are not afraid to use a LOT of them, and also not afraid of cutting them open when you need to change someting. I keep a cheap diagonal cutter and a bag of assorted cable ties in every desk drawer in my house (3 "kits" in total).

    Its easy to work with, extremely flexible, and best of all: cheaper than most of the fancy "solutions" you can buy.

      • I haven't tried this, but wiki says [wikipedia.org] you can "open without cutting it, the ratchet box can be crushed vertically using pliers.".

      • Diagnocal / side cutters are way safer than any burning method. If it burns the zip/lock it can burn the cable.

        You can remove the locker, or directly cut the tie. You just keep your eyes open and no wires cut, no hands cut :) and the cutting portion of those is so small anyways they are quite safe, unless your fingers are the size of ethernet cable.

        In any case, if you are unable to use side cutters safely, you maybe shouldn't touch any kind of tools.

We snip off the excess from the tie which can leave a sharp edge. To deal with that, honestly, we just try to cut them off as close as possible to the racket box, as horizontal as possible. That usually results in a smooth'ish, non-sharp end. I will say that our racks look very neat, almost artistic, although we have practically no serv

    • Velcro ties do something similiar, are reusable, cheap as well. The proble with your basic cable tie comes when you need to add or change a cable. If it's a medium size, you need quite a decent cutter, and then you need to cut them all and used new ones - when adding cables, I've seen people forgo the cutting step and just add more and more cable ties around the existing bundle, it becomes a nightmare if you need to access one in the middle.

      My solution is to use a whole bunch of solutions:
      - Instead of cable ties, we mostly strips of double-sided velcro. It's faster to reconfigure. (Hint: Buy "Velcro Plant Ties" instead of cable ties... it's the exact same stuff but much cheaper.)
      - Also use cable ties and twist-ties liberally.
      - CableDrop [bluelounge.com] (or similar) when you want to hold a cable in position but be able to move/remove it frequently.
      - AnthroCart [anthro.com] cable management accessories. They are optimized to work with their line of desks, but some of the accessories are just generally useful for group cables.
      - Medium-length runs of multiple cables can be grouped together using a split tube (e.g. this [newtechindustries.com]). Ikea used to sell some dirt-cheap split-tube for cable management, but I can't find it anymore (they do have these [ikea.com], though).
      - For some runs, braided sleeving [cabletiesandmore.com] (or even just solid PVC tubing from any hardware store) can be useful. You can unplug all the cables from both ends, and move it as a unit to a new span.

      So I guess my advice is to have a mixture of solutions on-hand. For any given task, use the one that feels right!

    Cable ties are too permanent. I have seen too many times where they get cut off to trouble shoot and never put back for various reasons. Use Velcro to bundle up the cables because it is easier to take off and put back on when needed. No tools required.

    Choose and use good cable management trays. There are lots of choices. Decide if you want the trays to have covers or not. I like the horizontal trays to be the type without covers and the verticals to have wide gaps with hinged covers.

    I don't like the Panduit Panduct type stuff (http://www.panduit.com/Products/ProductOverviews/WiringDuct/index.htm) because they require you to cut tabs out for passing more than a few cables in and out at a time. They also tend to tear up your cuticles when working with them. Also, the covers snap on and off and people put the smaller horizontal ones in the weirdest places. -- Hard to find.

    You can use different cable colors for identifying certain things in your environment (wireless, printers, servers, etc). If you can't justify buying all of the cables sizes you need in all of the different colors then you can use colored tape or some other type of identifier like plastic tags. You have plenty of options.

    Lastly, limit access to the wiring closets only to those that need it, have been trained, and are held responsible if it becomes a mess.

    Like any addiction, the first step is to admit that you've got a problem. :)

    Seriously, though. You've got to realize that whatever the result of your efforts is, it's still going to be non-ideal, even if it looks as uniform and as neat as humanly possible. The truth is, no matter of initial neatness will prevent someone from coming along and fucking it up, whether unintentionally and with good cause or because they're a lazy git.

    At home, I will label both ends of a cable that is likely to be sitting in a pile with other cables (usually - particularly when they're likely to be confused with others and when tracing the cable will be difficult). Just a simple file folder label or piece of tape, usually. Mostly, I don't worry about it, because at home "oops, I unplugged the system" only bothers me and/or my family. At work, it's another story: everything you do should be done to help mitigate downtime and improve your ability to effectively work with the cabling.

    On server racks, I prefer a handful of techniques. There are a couple principles I abide by:

    * always assume the rack will get messy over time
    * your original intent will not be the intent of the next person to come along
    * never assume a standard, because everyone has a different idea of how things should be done, and first impressions to that effect can be wrong
    * standards only make sense when the implementation requirements/specifications/etc. are identical/universal, eg. with electrical wiring or in a large hosting facility where everything is the same or there is a standard which can be applied to. This isn't usually the case with most colocated racks or with most server rooms, in my experience.
    * "Do things right the first time so you don't have to do them again". This applies generally to things like figuring out which cable goes where. "Right" is not necessarily the most aesthetic or "neat" option, but it is the laziest and most time-efficient, with an eye for long-term maintenance.

    The techniques are:

    For ethernet:
    * ethernet should not be bundled approximately 5 per group.
    * ethernet cable should be a rainbow of color, with different colors in each bundle. Eg: a bundle should have blue, green, red, white, etc. not multiples of any given color. This helps drastically when determining which cable goes to which system.
    * Jack ends should be labeled descriptively and dated at the time of labeling. The description should describe the other end of the cable, not the end you're labeling (eg: sw2j5 for the 2nd NIC in server 5 that goes to switch 2 jack 5, or 'svr5n2' on the other end).
    * use generic (not the 'fancy' ones) velcro straps to bundle the cable
    * do not bundle the bundles, especially with velcro (because it will stick to the bundle velcro and make things a mess). To hold them up and away, I prefer using 6" ball bungees (http://www.amazon.com/Ball-Bungee-Cord-6-White/dp/B000S5TWWO) or similar,
    * DO NOT USE HORIZONTAL CABLE MANAGEMENT PRODUCTS. DO NOT. They make a mess of things and, more often than not, get in the way more often than not. The one exception to this is on a part of the rack where you've got a patch panel or switching which is likely to remain consistent through several server iterations.
    * Do not pull the Ethernet to one side of the rack only. "Alternate" the bundles of ethernet to each side (like pigtails, sorta).

    For power:
    * Do not use the 6'+ power cables unless you need to. The cables are big enough and cheap enough to buy them in shorter lengths so you do not need to bundle them as much and the bundles are neater.
    * Label both ends with the name of the system in question (UPS side) and the UPS in question (server side).
    * Color code, if possible, by UPS. IE, if you have 2 PSUs per host, the first PSU gets black cables which go to one UPS, and the second gets grey cables which go to the other.

    One of my first network gigs, they converted from twinax to Cat5 for an army of 5150 terminals. Some glad to get rid of triax, but as they brought up the twisted pair terminals, they had trouble keeping some of them online for more than a few minutes. IBM subbed the cabling work out, and it took them weeks to give up and admit they had no idea what was wrong.

    At this point the powers-that-be were discussing the problem in the machine room, and their telecom tech was feeding another stick of gum into his mouth when I asked if they could stand a little advice. I recommended they loosen the cable ties that they used to bundel up the cable runs in the room and the various MDF rooms, they were pretty but very, very tight. Solved the problem. Turns out twinax waveform at the time was essentially a square wave, and UTP is not sielded like twinax. Crosstalk was the culprit. The clue? One big complaint from users was that they would get someone else's session for an instant on the scrren, then the terminal reset and they had to log in. Another session? Not exactly, but it did sometimes paint a little of screen from another session (cable) before it flipped out. Very unusual.

    This should not affect Ethernet, being resistant to all forms of interference including crosstalk etc, but no point in testing the theory. Velcro ties don't cause the crimping that ties do, and that crimping was the culprit. Compression shorts do still happen, not as often as they used to in telecom.

    And yes, plant ties are the bargain. Maybe soaking a few rolls in black dye to avoid the stigma of 'plant' ties will give you the panache you were looking for. Salt water sets the dye, avoids ruboff and black fingers. Or sell green as the new black.

When they snap I tend to pull everything out of my office, vacuum and mop the floors, scrub the desk down and generally file all my shit. Then I go down to the kitchen and grab another 8 or so rubber bands and set everything up again. This both works well to keep cables off the floor and provides a handy timer to remind me to tidy up my office. And best of all those rubber bands are free.
