This chapter contains information on powering options supported by RUT300 routers.

Power socketEdit

The router has a 4 pin power socket and can be powered by a 7-30 VDC power supply unit (PSU). Refer to the image below for the power socket's pinout information:

 

If you decide not to use the standard 9 VDC wall adapter and want to power the device from a 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 connection and disconnection.

While the device is designed to accept input voltage of up to 30 VDC peaks, 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.

Passive PoEEdit

The device may also be powered by an Ethernet cable via the LAN1 port:
(Do not use in other ports!)

 

  • The device is NOT COMPLIANT with the IEEE 802.3af-2003 standard: powering the device from an IEEE 802.3af-2003 power supply will damage the device as it is not rated for input voltages of the PoE standard.
  • The device is NOT COMPLIANT with the IEEE 802.3at standard: it cannot power other devices over Ethernet.

Simultaneous powering

The device can be powered from the 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 the 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.
