Hello,
Sorry if I misunderstood your question, but RUT950 supports 10/100 Mbps speeds on ethernet ports. This information is available on the product page itself here.

Regarding the powering, the device is designed for 9-30 VDC. Higher voltage will damage the device. Even when the voltage is close to 30v, it is recommended to use additional safety equipment to suppress voltage peaks from the power supply.
Kind Regards,
Andzej
