following tools should the technician use to verify PoE availability to the phone?

Not A, I'd go with B here. Network taps are mainly for network traffic analysis, but you need a cable tester with PoE check to actually verify the power on that port. Pretty sure that's what the question is after.
Network tap won’t check for power-B is what you want here since only a PoE cable tester does voltage.
Nah, I don’t think A works for PoE-network taps just look at traffic. B is what actually checks for power on the line. Seen this tripped up folks before.
Definitely B for this. Only a PoE-capable cable tester can check if the switchport is providing power, not just data. Network taps won't help with PoE in this case. Pretty sure that's the right route.
B, not A.
Yeah it's just B.
Yeah it's B. A cable tester with PoE capability tells you if the port is supplying power, not just data. A network tap won't show power delivery, just network traffic. Maybe some confusion since both connect inline, but to check PoE specifically, it's the tester. Anyone disagree?
Maybe A here. Network tap can check what’s on the port, so I think it could show if PoE is there.
Its A. A network tap should show if data and power are both present on the line, right?
Be respectful. No spam.
