Serial
The stick has a TTL 3.3v UART console (configured as 115200 8-N-1) that can be accessed from the top surface: it's near the SFP header. TX, RX and ground pads need to be connected to a USB2TTL adapter that supports 3V3 logic.
Note
Some USB TTL adapters label TX and RX pins the other way around: try to swap them if the connection doesn't work.
Setting MAC address
The MAC address can be changed via the manufactory menu:
manufactory -> set uni mac addr xx:xx:xx:xx:xx:xxRSTP bridge mode
Enabling RSTP bridge mode with set rstp bridge enable may cause loss of telnet access. If this happens, access can be recovered via UART serial console.
