If you look at the boots surrounding the crystal ends you will note that they use different styles of coverings. Since you have a colour issue, choose an end cap for servers, a different one for routers etc. Use bare ends for end points, the FlexBoots for something else, you can even use the flat cables for stuff like phones, printers, etc. Since color is out, use tints. Black, blue, yellow, white, combined with the ends, and you get dozens of combos.

Cat 6 cables are a different thickness and are easy to tell apart. Stick with Black and white and blue and that covers routers, switches and uplinks. Cat5e, if you can see the color yellow, use that for the critical stuff like VM servers, Email gateways etc.

The most important thing is that you get with the people who touch your patch panels and enforce the standard... and if you can get them to do that consistently, write a book and share your secrets with the rest of us. But as you are forced to label everything, guys like me that come in after you will sing your praises as NOBODY labels their shit anymore.

And thanks for the badge.
