I took a look into that device, and it looks like it uses a 1000BASE-X. Out of the box UbiSwitch supports only 10GBASE-R on the SFPs by default. You can change this for ports 9 and 10 by cutting a jumper on the board. Details are in the forum post below.

The management CLI has now been released and can be uploaded on revision B of UbiSwitch. I have a feeling you have a revision A, which won’t run the CLI. You can check by looking at the part number underneath the heatsink. At present, the CLI doesn’t support changing the SFP type, but we will add that feature soon.
