Cable Management Requirements
Cable management requirements are to:
Bundle cables together in groups of relevance (for example, ISL cables and uplinks to core devices) to ease management and troubleshooting.
Use cables of correct length. Leave only a little slack at each end.
Keep cable runs less than 90% of the max distance supported for each media type, as specified in the applicable standard.
Keep copper and fiber runs separated.
Install spare cables in advance for future replacement of damaged cables.
Use color coding of the cable ties. The colors should indicate the endpoints. Place labels at both ends, as well as along the run
