 The firmware of the box contains the information for the conecting to the server.
 To get these information, you first need to register the new box in Palitronica's system.
+The frontend \footnote[https://steetdev001.z27.web.core.windows.net/] lists all boxes across all tenants and can be used for some operations but we will mainly use it to register a new box.
 
+In order to register a new device, you need some information including the `MCU Serial` and the `MAC Address` of the box.
+These two info are not directly readable on the box and require to use the calibration Raspberry Pi.
 
++ After flashing the FPGA and the base firmware, connect the ethernet cable of the box to a PoE switch on the same network as the Raspberry Pi.
++ On the Pi, run the `UDP server` script (on the desktop) in the terminal.
++ After a few seconds, the script should output the `MCU Serial` and `MAC Address` of the box.
+
+Now in the frontend, follow these steps:
+
++ On the sidebar, select `Inventory`
++ On the top right corner, select `Dev2 Lab` in teh dropdown menu.
++ Verify that no box with the same `Device Id` already exists in the inventiory.
++ Click the #sym.plus icon in the top right corner.
++ Fill the informations as follows:

+
++ Click `ADD`
+
+Once the device is added to the frontend, you can find the connection string in the IoT Hub #footnote[https://portal.azure.com/#browse/Microsoft.Devices%2FIotHubs]
+
++ Select iothub-eet-dev-001 in the list.
++ Under `Device Management` #sym.arrow `Devices` select the new device you registered.
++ In the ` Primary connection string` select the part after `SharedAccessKey=`. Make sure to exclude the first "=" sign after `SharedAccessKey` but include the last "=" at the end of the connection string.
