i just bougth a CRS210-8G-2S+IN.
according to spec sheet https://i.mt.lv/routerboard/files/CRS21 ... 150201.pdf it can be powered on ETH1 by PoE (Passive and IEEE 802.3af/at).
Howeverm when i connect the device on ETH1 to my 802.3af/at PoE switches i can't power the device.
Is there anything i should consider/change?
Other devices using the same switchport & cable can be powered up to 25W (class 4).
Thank you for your help.
