    Some hints:
    • Leave some space, it might be a nice feat of engineering to pack 2" diameter cable bundle in a 2" space but thats too tight. Want the next cable run to be in there neat then leave some space, at least 3 times what is going in up front.
    • If you might expand, leave even more space.
    • Smaller bundles logically grouped. Putting everything in one big bundle makes it harder to work with. There is picture tidy and practical tidy, you want the later.
    • Pre-wire and provision all you can right up front to reduce add ons and mess grow. EVEN if it means potentially dead cable. Costs more in the short term but less that the long term. This eliminates the costs and needs to rip open the bundles every month for 10 years.
    • Before hiring someone, see their work. Yes, the other guy is cheaper but doesn't put the cables in tidy...
    • Specify in contracts (internal or external) that tidy inspections, not just functional specifications as need to be met before the job is considered done.
    • Realise the proportion of tidyness in the rack is proportionate to the quality planning. In fact, to know how organized a place is, ask to see their rackspace.
    • Add and use hooks along side the raceways just for new cable. When the hook gets full, bundle it off to the side. This is so your not forever rebundling cable.
    • Consider a distributed model where all the cable is decentralized in smaller chunks with high speed uplinks. "One Big Switch" is often one big mess no one wants to touch.
    • Get management support for policies on above. You may need to rectify an techie who just throws a cable over in a disorganized way, make them follow up and do it right.
    And after a couple of years work when cables fail and ports fail and switched fail etc etc you cabinet will look normal like the rest of ours...

This meant loads of unused sockets, all shouting, "please shove something in me!" You can guess the consequences.

    Eventually decided to take the patch leads out for the unused sockets. Nightmare!! 150 odd leads, all 2m, none labelled, with connections done entirely randomly. Aarrgghh!!

    Another example of, "it's only a school, it'll do!"??

    P.S. Agree 100% with Geoff's checklist.

    Re: How do YOU wire your data cabinets?

    I opted to waste an evening creating a bunch of 50cm patch cables while watching the TV at home one evening... Takes a while to sort it all but there's a lot to be said for taking the time to replace long wiring like that nightmare above and do the labelling too..

    Makes troubleshooting when stuff fails a lot easier.

    Re: How do YOU wire your data cabinets?

    I find that sometimes if you have the patch panel above a switch you can send the cable betwen the patch panel and switch to go around the back of the switch and then up from the bottom of the switch and then into the switch. Gets rid of any excess. Also you can get some rack mountable cable tidy things that hold all the excess cable in a fairly neat fashion. I took these out though as I am forever needing access to the cables.

    Re: How do YOU wire your data cabinets?

    All this gets to be even more "fun" when trying to install audio (that really needs keeping clear of mains), video and data in one rack.

    I have come to the conclusion that the back of a rack can be tidy or easy to work on. Not both. If the cables are tied into bundles and to bars, it is a swine to get the kit out of the rack for repairs without having the back and sides off too.

    This is the top half of my server cab, I am in the process of removing the red patch leads for custom made (by me) purple ones (as those in the middle switch.

    Re: How do YOU wire your data cabinets?

    I'm liking the staggered switch, patch panel, switch style. I think I will go for this when I have one of my cabinets moved this summer.
