Overview

The XGS1250-12 is a 11 + 1-port Multi-Gigabit L3 switch. It has 8 Gigabit ports, three 2.5/5/10GBit Ethernet ports and one SFP+ 10GBit uplink cages.

Power is supplied via a 12V 2A standard barrel connector. At the right side behind the grid is UART serial connector. A Serial header can be connected to from the outside of the switch trough the airvents with a standard 2.54mm header. Pins are from top to bottom Vcc(3.3V), TX, RX and GND. Serial connection is via 115200 baud, 8N1.
