First thing about cable management...... it takes time and documentation.
Couple things I try to do whenever I take control of a network.
- Color codes my cables when possible, easier to due with copper than fiber.
- Management (Blue)
- Production (Green)
- Cross-over (Yellow/Purple) strip over electrical tape at each end.
- Test-Quarantine (Black)
- Console ports (Pink)
- Cable Serial Numbers (Number goes end-to-end)
- Number at connection point
- Number as it leaves the Rack (top before it goes into tray/under the floor)
- Number as it enters the Rack (top before it goes into tray/under the floor)
- Number at connection point
- Descriptive label at each end for definition
- Fiber on one side and copper on the other side of the rack.
- Say no to extensive service loops. Try to get the cable within 1 meter of connection.
- I like to run all my console ports back to a centralized location so I can plug into one spot instead of putting my hands in the back of the cabinet. Saves me from disconnecting power, cables, or other items accidentally.
