zajímají mne Vaše osobní zkušenosti s použitím power injectorů. Trošku mi uniká význam užití aktivních power injectorů oproti pasivním. Teorie mne moc nezajímá, jaké jsou Vaše postřehy z praxe? Já jsem kromě toho, že passive POE neodpovídá standardu nenašel žádný problém. Více povím po ročním ostrém provozu
. Test jsem prováděl i s větší a delší zátěží a hodnoty byly pořád stejné. Tedy bezchybné.Provedl jsem malý test:
Co z toho usoudit nevím.
AIR-PWRINJ3 (cena cca 1000 CZK)
Minitar passive POE injector (cena cca 75 CZK)
AIR-AP1131AG-E-K9 (cena cca 8000 CZK)
AIR-AP1242AG-E-K9 (cena cca 10000 CZK)
