    Data Comm Cabinets (over capacity)

    I have a question in regards to the NEC code book. Howwould a data comm cabinet that is overrun with cables (completely full datacabinet) and you are not able to close the cabinet door. Does this fit into theNEC code or violation of not being able to close a data comm cabinet door dueto it's oversized capacity of patchcords, cables, switches, etc.

    does it say anywhere in the code book the doors have to close.?

    they are not even required to have doors AFAIK.

    It seems to me that the only potential problem, and not an NEC problem at that, is whether the air flow for cabinet cooling was designed assuming a closed front and back.

    possibly under 645.5(C) - subject to physical damage

    istm that using correct (minimal) cable lengths and good routing would prevent such a problem.

    pictures?

    Your question right there is why I have no use for IT people. That kind of work is their trademark. No matter how nice it looked when first installed by a networking contractor, as soon as these guys get their hands on it it turns into a stinking pile of garbage like you have.

    Unfortunately workmanship is not an NEC issue. As a LV project manager I would think that it's your responsibility to clean it up.

    Shame, especially with LV. Did a Hilton project many years ago; they had their own IT guy to do finals on the rack. 24p PP, switch, repeat down rack. needed 6" cords. Got 3-15'.

    The ugliest LV work I've done when I was brand new still looks better than what a careless IT guy will do to a rack in an hour. I'll never get it; one can order a thousand 6" or 1' cables for next to nothing. Screwing around strapping that extra 2-14' or having it in the way is not only making it ugly, but slowing you down, and they cost more as well.

    Not a dig on the OP tho imho he is looking at the wrong problem. Put in the right cable lengths routed correctly, and the doors should close, barring a spec/design flaw. and it will look nice, not like a wire shredder vomited up a bunch of catx cable. I guess it's a POV thing; as a hardware installer, I want to be proud of the wiring. I guess a software guy couldnt care less about that as long as the system works reasonably fast and is secure?

    Thing is, there are good IT people that take real pride in their work; not many, but I've had the pleasure of working with a few of them. Some of their wiring was in the class of old-school telephone or broadcast installations, and these are the kind of people that don't just move a patch, they pull it all the way out and re-run from the beginning.

    There have also been racks I wanted to take a Garden Weasel to.

    About ten years ago there were contests among IT jocks to untangle Cat 5 cables.
    A standard mix of cables was tumbled for a specific time in a dryer, the ball was handed to the contestant and the timer stopped when the last cable was tossed aside separate from all of the others.

    Tumbling in a dryer= IT cable management. I'm surprised they just didn't say "looks good to me" then pull the plug ends out of the ball and plug them into the rack.

    On a related note- in this months EC&M there is an article about PoE. Towards the end it talks about PoE powered/ethernet controlled lighting and how it could become the responsibility of the IT people.
