Ask Slashdot: Clever Cable Management?

sooth... writes "What clever ways have network administrators found to cleanly sort varying length patch cables within IDFs, BDFs, and MDFs or simply wiring closets? Pictures or examples are welcome." Since not everyone is a network administrator, let's expand this to include efficient or clever management of other cables. How do you route your computer cables (internal or external), your entertainment center cables, or any other corded setup?

Velcro!

[IversenX]

I found a solution which I'm pretty happy about.

Take a good piece of double-sided velcro (that will bond to itself), about 10-20cm. Get a short, screw with a large, flat head. Put the screw through the middle of the velcro strip, and screw it onto the underside of your table, somewhere out of sight. Rinse, repeat.

Now you have velcro loops that can carry all your wires really neatly, with infinite and easy reconfigurability.

(Initially, I tried gluing / velcroing the velcro strips on. It never lasted, so I went with screws instead. That really works!)

I have another, related question:

[Anonymous Coward]

How do you manage the pile of external power supplies for hard disks, routers, switches, phones, etc.? Is there some way to power external computer peripherals from the ATX power supply? I have a bunch of 12V 2A wall warts that keep drawing power even when the attached device is off. I think I should be able to power these devices from the ATX 12V rail, but I can't seem to find a product that allows me to safely attach external devices to the internal power supply.

Do not forget Plastic Spiral Cable Wrap!

Used to group sets of cables, relatively discretely.

[RedHat Rocky]

Agreed, really long runs of spiral wrap is no good.

Secret:
Use 2 inch lengths of spiral wrap, every foot or whatever makes sense.

Easy to add new cables, remove old without disturbing the bundle (unwrap one half, add/subtract, rewrap, repeat on other half).

Loads of cable ties!

[SplatMan_DK]

I think cable ties 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.

Just stop being afraid of cutting them open when you need to!

Re:Loads of cable ties!

[JustinOpinion]

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 (or similar) when you want to hold a cable in position but be able to move/remove it frequently.
- AnthroCart 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). Ikea used to sell some dirt-cheap split-tube for cable management, but I can't find it anymore (they do have these, though).
- For some runs, braided sleeving (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!

Potted Plant Hangers:

[pecosdave]

At one job where I had little ability to run cables under the floor/through the walls, but had a bunch of thick multi-microphone cables plus a few other types to run I made my own "hanging cable tray" using upside-down potted plant hangers I found at Lowes,

I was only going to run them from the punch-down panel to the first audio rack, the client liked the idea so much they bought more and ran them all the way to the wall for the cables they didn't hire me for.

Velcro, good cable trays, and use of color.

[Monoman]

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.

Cable ties are sometimes overrated

[rickb928]

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.

I use rubber bands

[davesag]

We always seem have have millions of spare rubber bands in our house so, for my home office cabling needs, I affix ethernet and phone cables to the tops of the legs of my desk to prevent my kicking them by accident, using rubber bands.

Now rubber bands don't actually last that long, a few months at most, before they dry out and snap. 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.
