This mode serves for uploading or backing up the operating system, or for restoring access to the device (restoring the default password via OS reflash, changing the network configuration or enabling/disablíng the SSH access). Only the service web interface is available in this mode, all remaining device functions are disabled. This mode does not publish mDNS record.

The service mode is accessed using the SERVICE button located above the red LED on the Unipi Gate device front plate. As the device's Ethernet ports work in bridge mode (br0 = ETH0 + ETH1) when the device is in the service mode, the ports should never be connected into the same network. The mode is physically indicated by the PWR diode continously emitting with the remaining LEDs blinking (demonstration here / startup simulator here).
As the next step for both cases, enter the device's IP address into your web browser's address bar. Upon confirmation, you will be connected to the Unipi Gate service interface.
Upon opening the service interface, you can see a blue ribbon on top of the screen and four dialogue windows.
On the right side of the ribbon, there are two buttons:
Under the ribbon are the following dialogue windows:
If Mervis is used, the Settings dialogue window can contain 3 additional buttons.
