+# Hisource Hi-K0801WS
+
+Following is documentation for unmanaged switch marked as `Hi-K0801WS`.
+
+Using SPI clamp in-board is the only method for initial installation.
+
+### Label specifications
+
+- **Name**: 2.5G Ethernet Switch  
+- **Model**: Hi-K0801WS  
+- **Ports**:  
+  - 8 × RJ45: 10/100/1000/2500 Mbps  
+  - 1 × SFP: 1000 / 2500 / 10000 Mbps  
+
+### What works (expected from label + similar devices)
+
+- All eight 2.5GBASE-T RJ45 ports at 10/100/1000/2500 Mbps  
+- SFP port supporting 1G, 2.5G and 10G modules 
+- LEDs
