Traditional: Two Devices and Two PoE's
PoE Passthrough: Two Devices and One PoE
This configuration is only possible when the Ubiquiti device has a secondary Ethernet port which can be activated for PoE Passthrough. When enabled, the device allows Power over Ethernet (PoE) power to pass from the main port to the secondary port, thereby powering an additional device.
From within the airOS AC configuration console, navigate to the Settings tab, go to Device and enable PoE Passthrough.
From within the airOS M configuration console, navigate to the Advanced tab, go to Advanced Ethernet Settings and enable PoE Passthrough.
PoE Linking: Two Independently Powered M Devices and One PoE
This is only valid for airMAX M devices. It is a similar configuration to the previous one, but with an added feature. If you power the first radio through the "Secondary" port rather than the "Main" port, power is not lost to the next device if the first radio is rebooted.
PoE Bridge: Two Devices and Two PoE’s
For this configuration , there is no need (and also no possibility) of a switch or router.
PoE Bridge and Passthrough: Three or Four Devices and Two PoE's
This configuration is only possible when the Ubiquiti device has a secondary Ethernet port which can be activated for PoE Passthrough. When enabled, the device allows Power over Ethernet (PoE) power to pass from the main port to the secondary port, thereby powering an additional device.
From within the airOS AC configuration console, navigate to the Settings tab, go to Device and enable PoE Passthrough.
From within the airOS M configuration console, navigate to the Advanced tab, go to Advanced Ethernet Settings and enable PoE Passthrough.
