+# Lianguo HYWS-SGT0108S
+
+Following is documentation for unmanaged switch marked as `HYWS-SGT0108S`.
+
+Original software is running UART on 9600 baud rate. Output is very minimal.
+
+Using SPI clamp in-board is the only method for initial installation and update.
+
+Stock flash chip is 512KB in size. Consider replacing for update through Web UI.
+
+- Header for uart is clearly identified.
+- The red LED act as a powered-on LED.
+- There is no SYS LED.
+- There is a footprint for a Reset button. Unpopulated. Unclear if routed back to RTL8373.
+
+### Label specifications
+
+- **Name**: 2.5G Ethernet Switch 8+1
+- **Model**: HYWS-SGT0108S
+- **Ports**:  
+  - 8 × RJ45: 10/100/1000/2500 Mbps  
+  - 1 × SFP: 1000 / 2500 / 10000 Mbps  
+
+### What works
+
+- All eight 2.5GBASE-T RJ45 ports at 10/100/1000/2500 Mbps  
+- SFP port supporting 1G, 2.5G and 10G modules 
+- RJ45 LEDs (Blue+White)
+- SFP Single LED (Blue)
