5 Powering Options

The RUT9xx router 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.
RUT9xx can 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 RUT9xx 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.
Though the device can be powered over an Ethernet port it is not compliant with the IEEE 802.3af-2003 standard.
Powering RUT9xx from a IEEE 802.3af-2003 power supply will damage the device as it is not rated for input voltages of
the PoE standard.

5.1 Powering the device from higher voltage

If you decide not to use our standard 9 VDC wall adapters and want to power the device from higher voltage (15 –
30 VDC) please make sure that you choose a power supply of high quality. Some power supplies can produce voltage
peaks significantly higher than the declared output voltage, especially during the process of connection and
disconnection.
While the device is designed to accept input voltage of up to 30 VDC, peaks from high voltage power supplies can
harm the device. If you want to use high voltage power supplies it is recommended to also use additional safety
equipment to suppress voltage peaks from the power supply.
