+### SWTG024AS-V2.0
+
+## Brands
+|Brand|Type|Managed|PCB|Flash|Chip RTL|
+|---|---|---|---|---|---|
+| hongyavision | LG-SG5T1 | No | PCB-SWTG024AS-V2.0_16895 | 25Q40 | 8272 |
+
+### Label specifications
+
+- **Name**: 
+- **Ports**:
+  - 5 × RJ45: 10/100/1000/2500 Mbps
+  - 1 × SFP+: 1000 / 2500 / 10000 Mbps
+- **Power**: 12V DC, 1A  5525 connector 
+
+<img src="photos/SWTG024AS-V2.0/label.jpg" width="300" />
+
+### What works
+The device is fully supported:
+- Port 1-4 2.5GBASE-T RJ45 ports work at 10/100/1000/2500 Mbps
+- Port 5 2.5GBASE-T RJ45 ports through RTL8221B not work (Wait to fix)
+- The SFP+ port supports 1G, 2.5G and 10G modules 
+- LEDs work with the same indiciations as the OEM firmware
+- Online update does not work with 512KiB flash.
+### PCB overview
+
+**Board markings**

+### J1, serial console
+
+| `J1` pin | Signal      |
+| -------- | ----------- |
+| 1        | GND         |
+| 2        | RX (Input)  |
+| 3        | TX (Output) |
+
+Note,`R52`、`R53`may not be installed.You need to bridge them using either solder or resistors.
+
+## Power supply
+
+Input power is delivered via barell plug, `12V 1A` adapter was provided.
