New construction. Want to check the builder's Cat6 Plus Ethernet cables. While the builder's sub installed all the cable, connectors on the hub end & wall plates for Coax/Ethernet, he didn't put connectors on the ceiling end for the three wireless access points. I'm not going to use the outdoors one, but will use the two inside ceiling locations.
I installed the connectors for the two ceiling WAPs. Looks like the builder used "A" wiring for connectors at the basement hub, but hard to say for sure. I did both as "A." Just bought a RJ45 Ethernet cable tester. If the cable's good, both end testers light up 1 through 8, then G, together, in numerical sequence. I tested some known good cables, the $10 tester seems OK.
For one outlet, circuit/test light #2
is blank on both end testers. Guess I'll try another ceiling connector, maybe it was me.
On the other outlet, the light sequence on the main tester is correct while the sequence on the secondary tester is reversed. Makes me think the sub wired that one as "B." Anybody know the meaning of one tester reversing light sequence? That possibility was not mentioned in the instructions. Thanks.
