EAP110 passive PoE power range
Does anyone know if the AP will be happy accepting 27v? I don't want to blow up my shiny new UISP switch. Does passive PoE out, but at 27V instead of 24V on the PoE adaptor.

Hi @TNHAU
It's not recommended to use the 27v switch to power on the EAP, it could damage the EAP, and this will also violate the warranty.
Passive PoE: A non-standard form of PoE. It can also be used to power over the Ethernet cable, but no negotiation or communication process is required. Passive PoE doesn’t conform to any IEEE standards. When using a passive PoE switch/adapter in a network, the power supply is "always on", which means that regardless of whether the end device supports PoE or not, it always sends current through the Ethernet cable at a certain voltage. Therefore, using a passive PoE switch/adapter that exceeds the voltage supported by the end device may burn the end device.

Hi @TNHAU,
As the power source, your switch should be fine, but the EAP110 could be damaged. I think most devices have some voltage tolerances, but there's no guarantee what would happen if it gets the full 27v.
