turn off this feature. Please refer to the following sections for more.

Another one for 10Mbps feature, “ON” to change the data transfer rate
of RJ-45 to 10Mbps. Then the device can transfer HD videos and extend
the transfer distance of RJ-45 to 330 meters simultaneously. And “OFF” to

turn off this feature

Also one DC 47V ~ 57V power socket for the PoE+ Media Converter.
