That's kind of like asking "My house is messy...can you tell me how to make it neat?" It's a very open-ended question, that doesn't have a good answer.

The only thing you can do is work through the problems, one by one. Trace down each cable, find out where it goes, and either schedule downtime or advise people that things may be unavailable for a minute or two, while you reroute/reconnect the cable. Go one at a time, and get them neat. Install wire guides and cabinets as needed. The best thing would be to get all your switches into one rack, and all your connections into patch panels in an adjacent rack, and buy a crimping tool, some decent cable, and a huge bag of RJ45 ends, and make your own patch cords of exactly the right lengths, so you avoid having huge loops if you don't need them.

Personally, I color-code things by buying different color cables. Switch-to-switch cables are one color, *Nix servers are another, Windows another, etc., but work out your own system for you.

Great advice, but a picture is worth a thousand words in this case. I learned rack and cable management by envying all the beautiful google datacenter pics.

That depends on the scale of your setup. my work place used to have a switch room and it was wall to wall switches. was't too long before someone started mistakenly pulling/plugging in the wrong cables. now it is grouped by the project teams. so all of project A's stuff from switches to servers is in lab X row C.

are not jokes. They are advice.

also, googling 'learning cable management' will net you some results that you can use.

also, going to youtube, since this is really a physical hands on and experience question that no one is going to be able to explain to you, sort of like no one will teach you how to swim by explaining it, will net you this:

That's along the lines of some things I've seen before. My favorite was opening a closet (at a Fortune 100 bank!), to find something that looked like someone shot a cable-monster with a shotgun. Some highlights:
  1. Cables were DIRECT RUNS from the closet to the back of the PC. NO patch cords on either end.
  2. Cable broke? End was cut off...along with the cable-number, and a new end was put on. So, no labels on most of it.
  3. Numbers? Naah..some of the cables had KNOTS in them. 5 knots = cable #5, and so on.
  4. The number one? A working switch had the power cable tied around the middle of it...because it was HANGING IN MID AIR by the power cord...because the cut-off cables (see #2) were too short to reach the rack.
Yes, the guy was fired, and professionals were brought in. One weekend per floor..for 32 floors. And it was a thing of beauty when it was done.

Ok, if we're talking "interesting" cabling, I had the unfortunate job of having to deal with 10BASE2 network installations that had to be done "at a price point". Couple of computers, no problem, 50 machines across two floors, bit harder.

Highlights.....
Dropping a cable externally from a fourth floor window down to a second floor window and just drilling holes in the window frame and leaving it "loose".
Having to sneak a cable across a street (lucky the buildings the company had were quite high), I went back a few years later and the cable was still in place.

For the benefit of the OP:

Where you're stuck with having to mix voice and data on the same patch panels use different colour patch cables as it can help with tracing. The other pictures showing nice bundles down the side are all great until you have to trace a cable, that's when labelling ends can be your friend.

Get patch cables where the "tongue" is protected in some way so that if you are having to get a cable out from a large bundle you can pull it a bit without breaking the tongue off.

THROW AWAY any cable with a broken tongue, really, seriously, DO IT!!!!!
