​Follow these guidelines to manage documentation at your cabling plant: Keep your cable plant documentation in a centrally accessible location. Make sure it includes locations, installation dates, lengths, and grades of installed cable. Label every data jack or port, patch panel or punch-down block, and connector or circuit. Use color-coded cables for different purposes and record the color schemes in your documentation. Cables can be purchased in a variety of sheath colors. For example, you might want to use pink for patch cables, green for horizontal wiring, purple for DMZ lines, and gray for vertical (backbone) wiring. Be certain to update your documentation as you make changes to the network. The more you document, the easier it will be to move or add cable segments in the future.
