    Network cabinet cabling layout

    So, we've got a cabinet going into our new building which I have now planned the layout of. What do people think of this layout? Too much cable management? There's going to be 86 cat5e cables, and 3 fibre patch leads to manage.

    Patches below the switches is what I was taught and have always done, but otherwise look good.

    I would be inclined to mix things up so cables don't have that far to go to the switches, and to minimise the amount of vertical cables that end up getting in the way. I've attached a photo of the top half of a 42U cab that I think has a similar amount of stuff to what you want.

    Can't do it that way. One switch is 24port PoE, One is 24 port normal and one is 48 port normal. So, we have 3 switches to deal with. And I don't want short cables, as they don't follow the Cat5e spec (anything less than 0.5m IIRC).

    Your nuts I love short patching have a 2 x 24 panels sandwiching a 48 port switch works so well.

    Because the cables are unable to 'twist' inside the sleeve for a long enough distance in order to ensure they are working properly. CCNA covers this somewhere. Don't think its specified anywhere, but it is simple physics. IIRC the minimum recommended length is 0.5m.

    It does state in CCNA fundamentals about the minimum length should be 0.5m for parity reasons.

    We do 3 1U patch panels switch, same again and use 1/4m patch leads or 1/2's where needed, makes it a lot tidyer and gives you more space and no need for as many cable management racks. I would show you the pictures of what we have done but do not have them handy at the moment on my pc.

    You don't seem to have any vertical cable management? Also, is there any room to grow? I know you'll be absolutely certain now that that will never be needed but if things change and there's no space to grow then it's way more expensive to change it later.

    No room to grow - no room in the room where the cabinet is going for it to grow! And vertical cable management is interesting - I'll have to look at that. Not got the cabinet out the box yet, so don't know what sort of space there is.

    I'm quite a noob to cable management at the moment, i re-cabled a cab recently but it was my first ever one. i had a look at your diagram and it is something i would do, It looks logical...
