+## Brands

+### Label specifications
+
+- **Ports**:
+  - 4 × RJ45: 10/100/1000/2500 Mbps
+  - 2 × SFP+: 1000/2500/10000 Mbps
+- **Power**: 1A @ 12V DC
+
+#### Xikestore SKS-3200-4E2X label
+<img src="photos/SWTG024AS-V2.1.0/label.jpg" width="300" />
+
+### What works
+- ALL 2.5GBASE-T RJ45 ports work at 10/100/1000/2500 Mbps
+- The SFP+ ports supports 1G, 2.5G and 10G modules.
+- LEDs work with the same indiciations as the OEM firmware.
+
+### PCB overview
+
+**Board markings**
+- Top silkscreen: PCB-SWTG024AS-V2.1.0

+
+### Serial console
+
+The four-pin through-hole serial header can be seen to the right of the CPU heatsink in the photo above. It is labelled J1, with pin 1 (Indicated by a triangle on the silkscren) at the bottom. the pinout is also on the silkscreen:
+
+| Pin | Label  |
+|-----|--------|
+| 1   | TX     |
+| 2   | RX     |
+| 3   | GND    |
+| 4   | 3V3    |
+
+Adding a header is a few moments work with a soldering iron. Only pins 1-3 are required for serial port use, and the stock firmware outputs at 57600bps at boot.
