Further to the post by @josh_elijah above, this feature is now available for UbiSwitch in software! No soldering `SM1` bridge is required! Changing the PCS mode on ports 9 and 10 can be done using the BloxOsLite CLI.

Steps:

1. Ensure you have version 0.4.0 or above installed on your UbiSwitch. See [here](https://github.com/botblox/bloxoslite-releases/releases) for public releases and [here](https://botblox.notion.site/Upgrading-1160ca7860eb80a99b64c0bc843a9d3c) for documentation on updates over UART.
2. Boot up UbiSwitch and then connect a 3.3V TTL UART-USB converter to open a serial console on your dev machine.
3. Follow the instructions for setting PCS mode on ports 9 and 10 [here](https://botblox.notion.site/Port-MAC-and-PHY-status-control-fdb543a902374345b10c1a5254666017#1880ca7860eb80cdbaf0cfb4c7116b1d)
4. Some examples:

`port 9 mac mode 10gbaser` for 10Gb SFP that does not support inband auto-negotiation with port MAC.

`port 10 mac mode 1000basex` for 1Gb SFP fiber.
