Getting UbiSwitch ports working with a 1G SFP

[botblox_admin]

– Rephrased from a customer email –

I want to use UbiSwitch with 1G SFPs. I heard this is possible but requires some jumper I need to change. How do I do that?

Ports 9 and 10 can be easily configured to work in 1G mode, instead of the 10G mode that the board ships with.

1. Locate SM1 jumper
   

   

2. Cut the track between the two pads with a scalpel.

3. You can resolder it to re-enable 10G operation.

For port 0, the process is a bit more involved, and is detailed in this forum post.

UbiSwitch 10G Port configuration preference?

I think what you’re asking is, is there a preference for how each three of the 10G ports on UbiSwitch is configured. There are 3 10G ports on UbiSwitch, port 0, port 9 and port 10. Ports 9 and 10 can operate one of three modes: Mode 1: SGMII/1000GBASE-X/2.5GBASE-X Mode 2: 5GBASE-X Mode 3: SFI/USXGMII Port 0 can operate in one of six modes Mode 1: SGMII/1000GBASE-X/2.5GBASE-X Mode 2: 5GBASE-X Mode 3: SFI/USXGMII Mode 4: RGMII Mode 5: RMII Mode 6: MII This is a little confusing.

Once the UbiSwitch management software is released, this will all be possible via software.
