Following is documentation for unmanaged switch marked as `KP-9000-6XH-X2`.
Following is documentation for switches marked as `KP-9000-6XH-X2` or
`KP-9000-6XHML-X2`.
Using SPI clamp in-board is the only method for initial installation.
### Label specifications
- **Name**: 4X 2.5G RJ45 Port + 2 X 10G SFP+ Port
- **Model**: KP-9000-6XH-X2
- **Model**: KP-9000-6XH-X2 / KP-9000-6XHML-X2
- **Ports**:
- 4 × RJ45: 10/100/1000/2500 Mbps
- 2 × SFP+: 1000 / 2500 / 10000 Mbps
### Machine target
These devices exist with different PCB revisions. Select the machine target by
the PCB silkscreen, not only by the label on the case.
| PCB silkscreen | Known labels | Recommended machine target | Legacy target |
| --- | --- | --- | --- |
| `2M-PCB43-V1.2` | `KP-9000-6XHML-X2` | `MACHINE_KP_9000_6XHML_X2_V1_2` | `MACHINE_KP_9000_6XHML_X2` |
| `2M-PCB43-V2.1` | `KP-9000-6XH-X2`, `KP-9000-6XHML-X2` | `MACHINE_KP_9000_6XH_X2_V2_1` or `MACHINE_KP_9000_6XHML_X2_V2_1` | `MACHINE_KP_9000_6XH_X2` |
The V1.2 and V2.1 boards use different GPIO, SFP, port and LED mappings.
The unmanaged and managed labels are firmware/SKU differences and do not by
themselves identify the PCB wiring.
