No mention of Power-over-ethernet?
- mark-r 7y agoWhat is the maximum power provided by PoE? Wikipedia is surprisingly vague on the subject, probably because there are multiple standards. PoE was never intended to power more than just network equipment.
- mumrah 7y agoI think it's something like 30W over a single ethernet cable. I'm running a few devices with PoE that are not network enabled, just conveniently located near an ethernet cable that's not near a power outlet.
- steve19 7y agoI am not sure how Wikipedia can be more explicit, they even have a table showing the voltages and wattages of the different standards. [0] According to that table, the latest standard, 802.3bt Type 4, can provide 71 W to the device at the end of the cable (and inject 100W into the otherside).

- vetinari 7y agoDepends on how you define "network equipment" :) Unifi is selling LED panels, that are powered over PoE and controlled over Ethernet.
- WorldMaker 7y agoI assumed the author dismissed it for the same reasons as USB-C that it requires active negotiation and isn't "simple" enough.
