+# SWTG018AS-A V2.0
+
+The following is a documentation for the unmanaged switch marked as `SWTG018AS-A V2.0`.
+It is e.g. sold under the Ampcom brand, but no branh-markings are found on the device.
+
+The original software is running UART on 9600 baud rate. 
+
+Using a SOIC clamp in-board is the only method for initial installation.
+
+The board has a single flash chips `BS` with 4M-bit size. The front switch, switches between the two flash chips.
+These can be programed independently by using said switch - so it is e.g. possible to run the original and new firmware in parallel.
+
+### Label specifications
+
+- **Name**: 9-Ports 2.5G Ethernet Switch
+- **Ports**:
+  - 8 × RJ45: 10/100/1000/2500 Mbps
+  - 1 × SFP+: 1000 / 2500 / 10000 Mbps
+- **Power**: 12V DC, 1A barrel connector 
+

+
+### What works
+The device is fully supported:
+- All 8 2.5GBASE-T RJ45 ports work at 10/100/1000/2500 Mbps
+- The SFP+ port supports 1G, 2.5G and 10G modules 
+- LEDs work with the same indiciations as the OEM firmware

+
+| `J1` pin | Signal      |
+| -------- | ----------- |
+| 1        | 3V3         |
+| 2        | GND         |
+| 3        | RX (Input) |
+| 4        | TX (Output)  |
+
+
+## Power supply
+
+Input power is delivered via barell plug, `12V 1A` adapter was provided.
