The extra cables came in handy when I installed an additional Ubiquiti Unifi Ap-AC Wireless Access Point on the downstairs WAP port. Cables work as expected. However, when I examined Cat6 cables, I found that the wires are staggered in the connectors to reduce noise. The wires in these RJ45 connectors run in a straight line, indicating that the connectors are Category 5. Otherwise no issues or problems.
