Simultaneous powering
The router can be powered from a power socket and over Ethernet simultaneously. In this case, both PSUs should have similar output voltages. 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.
