Using SPI clamp in-board is the only method for initial installation. -The board has two flash chips `BY25Q16BS` with 16M-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**: 2.5G Ethernet Switch -- **Model**: Hi-K0402WS +- **Model**: Hi-K0801WS - **Ports**: - - 4 × RJ45: 10/100/1000/2500 Mbps - - 2 × SFP: 1000 / 2500 / 10000 Mbps + - 8 × RJ45: 10/100/1000/2500 Mbps + - 1 × SFP: 1000 / 2500 / 10000 Mbps ### What works (expected from label + similar devices) -- All four 2.5GBASE-T RJ45 ports at 10/100/1000/2500 Mbps -- Both SFP ports supporting 1G, 2.5G and 10G modules +- All eight 2.5GBASE-T RJ45 ports at 10/100/1000/2500 Mbps +- SFP port supporting 1G, 2.5G and 10G modules - LEDs ### PCB overview **Board markings** -- Top silkscreen: PCB-KO4022W-V3.0 / DIP-KO4022WS-V3.0 +- Top silkscreen: PCB-KO801W-V2.0 / DIP-KO801WS-V2.0 Top side - + Bottom - + ### T2, serial console -| `J2` pin | Signal | -| -------- | ----------- | -| 1 | 3V3 | -| 2 | RX (Input) | -| 3 | TX (Output) | -| 4 | GND | - ## Power supply Input power is delivered via barell plug, `12V 1A` adapter was provided. -Board has two supply rails. `0.95` and `3.3` volt. - -### `0.95` Core Voltage - -Voltage is made by a `Techcode TD1720` . - -### `3.3` Voltage - -Voltage is created by chip marked as `Techcode TD1720`. - -**There seems to have been a miscalculation when choosing the inductor and the device is ~25% more efficient with an 5V power supply.**
