However, I'm forced to ask which kind of "good cabling" is possible in a dynamic environment when you plug in/out, change, etc. the cables. This seems to invariably lead to total chaos :-). For example, consider the case of a patch panel of 200 plugs, where you'd have to wire cables to 20 different physical locations (where the switches/routers are)? How do you manage that elegantly, at the patch panel side and the switch/router side? :-) I mean, it's fine if you take 100 cables, and wire them between the patches and the switches (or the racks if you have the patch cross-connect there) in bulk, but consider the case where you have 15 different switches (different subnets), a computer moving in/out of the room in a daily basis etc. You can't just go around wiring like http://thrashyour.com/lhr1-wiringdemo.jpg or http://new.onecall.net/timages/cat5patch.jpg How do you do good cabling in dynamic, real environments? :-) -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
