+# IG108
+
+Following is documentation for unmanaged switch marked as `IG108`.
+
+Original software is running UART on 9600 baud rate.
+
+Using SPI clamp in-board is the only method for initial installation.
+
+### Brands
+
+| Brand | Type | Managed | PCB | Flash | Chip RTL |

+| Netcore | GS9 | No | PB-2132 | cFeon Q32A | 8373N + 8224N |
+
+### What works
+
+- All eight 2.5GBASE-T RJ45 ports at 10/100/1000/2500 Mbps
+- SFP port with 1G/2.5G/10G modules
+- LEDs

+
+### Serial console
+
+The PCB has unpopulated through-holes near the SFP Port, with description of each pin, works out of the box.
+
+- **Settings**: 115200 baud / 8N1 / 3.3V TTL
+
+### Power supply
+
+Input power is delivered via barell plug, `12V 1A` adapter was provided.
