RUT955 Powering Options

RUT955 routers can be powered from a power socket or over an Ethernet port. Depending on your network architecture you can use the LAN1 port to power the device.

RUT955 routers can also be powered from a power socket and over Ethernet simultaneously. The power socket has higher priority meaning that the device will draw power from the power socket as long as it is available.

When a RUT955 device is switching from one power source to another it loses power for a fraction of a second and may reboot. The device will function correctly after the reboot.

Pin	Signal ID	T568A Color	T568B Color	Pins on plug face (socket is reversed)

2	TX-	green solid	orange solid
3	RX+	white/orange stripe	white/green stripe
4		blue solid	blue solid
5	7 - 30 VDC	white/blue stripe	white/blue stripe
6	RX-	orange solid	green solid
7	GROUND	white/brown stripe	white/brown stripe
8	GROUND	brown solid	brown solid

Though the device can be powered over an Ethernet port it is not compliant with the IEEE 802.3af-2003 standard. Powering a RUT955 device from a IEEE 802.3af-2003 power supply will damage the device as it is not rated for input voltages of the PoE standard.

Additional note: When powering the device from an external power source other than the included power adapter, make sure to use the correct voltage and polarity to power the router. It is highly recommended to test the router separately before connecting other I/O devices or serial ports in order to avoid damage to your equipment if you are not using the included power adapter.
