I have several RUT906. On the official Website it says it can be powered via PoE. In the Wiki the Router is not listed as PoE supported devices.
Before i prepare my installation can anyone help and tell me if powering the router with PoE will work and if i can use any standard injector within the range of 9-30VDC?
As long as you attempt to power the device over passive PoE with 9-30VDC the device should operate as intended. Anything above 30VDC will damage the device.
Any Passive PoE injector that delivers in-range voltage (I use 24v) AND IS ABLE TO deliver the wattage required … see spec of router for maximum power draw of device.
