Iniettore PoE 55v su access point con PoE-PD: 48 V

[7stars]

Buongiorno,
scusate se non conosco perfettamente l'argomento...

se un iniettore PoE ha specifiche 55v fino a 30W

funziona con un access point wireless con PoE-PD: 48 V nominale...

cioè va bene perché è maggiore ed è importante solo se non riesce ad erogare almeno 48v oppure non va bene lo stesso...?

Grazie

Rispetta le specifiche 802.3at o 802.3bt?
Secondo questo documento: https://www.versatek.com/blog/compatible-vs-compliant-poe-devices-mode-a-vs-mode-b/

Backward Compatibility
Although new features were added, higher power is supported and some algorithms were changed to ensure interoperability. The idea is that the system will work with legacy Type 1 and Type 2 devices. It should work automatically, as long as the PSE is capable (in terms of power) of supporting the PD and both are standard compliant. Should the PD require higher power (IEEE 802.3bt PD) and the PSE cannot support it (IEEE 802.3af PSE), the PD will either remain off or it will turn on and consume only the power available from the PSE.

access point 802.3af or 802.3at PoE
iniettore IEEE 802.3af,IEEE 802.3at....

quindi, in pratica basta controllare queste specifiche?
grazie :)
