on n'a 4 paramètres 24V 24VH OU 48V ET 48 VH
Mais si je comprends bien
V correspond à 802.3af ?
VH correspond à 802.3at ?
Je me trompe ???

48VH is not for 802.3af, it is used to power airFIBER 24, airFIBER 5, WS-6-MINI, MIMOSA, and other special high current demanding radios
Use 48V for most 802.3af devices like phones
24V is for most airMAX radios
24VH is only for AF2X, AF3X, AF5X, do not use this on normal airMAX radios

Also read the PDF as it explains what each POE option puts on the PINs (voltage and polarity).

Re: 802.3af/at
Please read the following wiki on PoE.
https://en.wikipedia.org/wiki/Power_over_Ethernet
Pay particular attention to section 8, https://en.wikipedia.org/wiki/Power_ove ... ity_limits and the table that shows what pins are used for Mode A and Mode B. As Chris said, they do not parallel the Netonix passive PoE 48V and 48VH.
Passive 48V energizes the same pins that Mode B does.
With great power comes great responsibility. Make sure you understand what pins the device uses for power and what the consequences are for which pins you energize.
All this said, you should not be posting such questions to the stories section. Please see the pink banner at the top.
