Proper, clean cable management (howto) forrie 05-18-07

I'm looking for some reference about how to do cable management
"right".

In all my years as a sysadmin, I never really figured this out. And
I've an opportunity now to build out a new lab *and* clean up the rats
nest cable job in our old lab ;-) Should be a joy ride.

I've been looking all over the place, and haven't found much except
products for sale, etc. One product for switches I liked is called
NEATPATCH.

My labs consist of switches and several servers - nothing out of the
ordinary (racks, etc).

I'd appreciate it if anyone had some pointers or perhaps pointers to
online reference (or books, even).

Thanks in advance.

Good links. I wish I had taken picture of the good and bad cabling
I've come across, and done.


Some thoughts;

Buy a bunch of 1ft, 3ft, and 3ft patch cords. cableguys.com is good
and cheap. (no relationship, etc)

Use this stuff as needed to span rows of racks or to get from the
rack row to the wall.
http://www.flextray.com/


For all the little cigar-box sized electronic boxes, I bought a desk
organizer like this and put it in on a shelf in a rack;

http://www.buyingpartners.com/product.php/item/MMF-2645BLA/MMF2645BLA.html

Never stack anyting on anything else. You should always be able to
move/remove any piece of equipment without disturbing anything else.


Give power distribution and cabling as much thought as the data. If
you are anal as i am, you can get NEMA cables in 2ft and 3ft
lengths. They are cheap. Newark Electronics (newark.com) sells short
cables and the sell over the phone and always took my small ($100)
orders. They *used to* send a huge catalog out to anyone that
asked. Keep an assortment of old NEMA cords, sorted by length.

Wiremold makes rack-mounted power strips (p/n J06BOB20X-AM & others.
They are annoyingly expensive, but there is a value to neatness.

Look at "power sticks" p/n 4810ULBC and others. Home Depot has them.

CabinetMATE Plug-In Outlet 4810ULBD Center - Ten outlets. 6' [1.8m]
or 15' [4.6m] cord. Length 48" [1.2m]. Receptacle center-tocenter 4"
[102mm].

I put two on each rack. One was masrked with red tape and plugged into
the UPS and the other was just house power. Each piece of gear that
needed UPS had red electrical tape around both ends of the NEMA cord.

Here's the WireMold catalog;

http://www.wiremold.com/shared_content/pdf/ed795.pdf

In the last place I built a computer room, I layed out a row of 7ft
racks (about 8 rack widths). I needed new power circuits pulled from
the panel, I had a 2x6 wood beam hung from the ceiling, the length of
the row, above it. [*] Then I had the electrician run receptical boxes
every couple ft on one side of the beam and cable mgmt loops on the
other side. Neat. Cheap.


[*] Today I would probably use the metal equivilant of a wood beam.
