+# ZX310S-4T2XT
+
+The following is a documentation for the managed switch marked as
+`ZX310S-4T2XT` and sold by Horaco.
+
+The original software is running UART on 57600 baud rate 8N1.
+
+CPU: RTL8372
+Flash: 2MByte Winbond W25Q16DV (U3)
+PHY 2x RTL8261BE

+  - 4 × RJ45: 10/100/1000/2500 Mbps
+  - 2 x RJ45: 10/100/1000/2500/5000/10000 Mbps
+- **Power**: 12V DC, 2A barrel connector
+
+<img src="photos/ZX310S-4T2XT/label.jpg" width="300" />
+
+### What works
+The device is fully supported:
+- All 4 2.5GBASE-T RJ45 ports work at 10/100/1000/2500 Mbps, including EEE
+- The 10GBit ports works, including EEE.
+- LEDs work with the same indiciations as the OEM firmware
