1. Choose Cat6 or Cat6A in the design
Category is a design and procurement decision. Acceptance verifies the installed system against that decision; it should not retroactively redefine the requirement.
Application and lifecycle
Document the intended applications, port use, power delivery, pathway constraints, expected service life, and owner standard. Use the designer's requirement rather than selecting a category from a marketing comparison.
Matched components
Record the cable, connectivity, cords or direct-attach termination, and any manufacturer-system requirements. A higher-category cable alone does not establish an end-to-end higher-category system.
PoE populations
Identify powered-device links and any project requirement for resistance-unbalance or other power-delivery test limits. Cameras and access points may use an MPTL topology that needs its own adapters and limit.
Change control
When a component, pathway, topology, or category changes, obtain approval and update the test basis before closeout. Do not leave the tester configuration as the only record of the change.
