====== Service mode ======
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 [[en:hw:025-gate:01-first-steps#mdns_record|mDNS record]].

===== Startup in a service mode =====
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 ([[en:hw:025-gate:led-indication#pwr_is_on_the_rest_is_blinking_600ms|demonstration here]] / [[en:hw:025-gate:led-indication#service_mode|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.
===== Description of the service web 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:
- **Run shell** -> serves for access to a console with limited options (BusyBox)
- **Restart system** -> reboots the device
----
Under the ribbon are the following dialogue windows:
- **Settings** -> contains four buttons, all of them useable only in the regular mode::
* Set DHCP on br0 interface -> sets the bridge interface to obtain the address from DHCP
* Set 192.168.200.200 on br0 interface -> sets the bridge interface to fixed 192.168.200.200 IP address00
* Enable ssh -> enables SSH access on port 22 (SSH is enabled by default)
* Disable ssh -> disables SSH access
- **Backup** -> contains the "Backup to USB flash" button which creates an OS back-up stored on a compatible USB flash disk (if inserted)
- **Software update** -> serves for uploading the OS into the device
* A text field for uploading the **archive.swu** (containing the OS image) is placed directly under the window's label
- **Messages** -> displays a list of performed operations
\\
If Mervis is used, the **Settings** dialogue window can contain 3 additional buttons.
* Enable Mervis -> launches Mervis RT on the device
* Disable Mervis -> stops Mervis RT on the device
