This chapter contains information on powering options supported by RUT240 routers.
The router has a 4 pin power socket and can be powered by a 9-30 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.
The device may also be powered by an Ethernet cable via the LAN port:(Do not use in other ports!)
The router 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 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.
