I am trying to run a sensor from my switch using POE. I have created a temp/humidity sensor using the MySensors directions https://www.mysensors.org/about/arduino. I decided to use a nano due to the USB connector. I have connected this to my switch via a TP-Link POE splitter set to 5 volt output.
When connected, the switch provides power for a second or two then turns off for 10 seconds or so before coming on again. I believe the Switch is testing the circuit not detecting enough power being drawn and shuts down. It then goes through the cycle again. Note: both the power LED on the switch and the nano LEDS light up while power is supplied. I believe the nano itself only uses about 20mA
I have tested with another device that requires 9volts (hand held phone) via the splitter and it works fine with power provided consistently.
I was wondering if there is some circuitry I can add before the Arduino that will draw a little more current but still provide a constant 5V to the nano.
Additional information. The switch is a Linksys LGS124P. I have tried to find more detail regarding the required power but can only find this datasheet that does not provide that level of detail http://downloads.linksys.com/downloads/datasheet/1224699456700/25685_LINKSYS_unmanaged_POE_switches_PROD_Revised.pdf
