dual boot changed to swos 2.18 no access possible

CRS310-8G+2S-IN Routeros 7.23.3. I switched from Routeros to swos in the routerBOARD. After reboot, no connection is possible. Switch ports will not be activated, only both SFP+ Ports. I also tried a downgrade to 7.21.4 doesn't work either.

192.168.88.2 is not up? That's the defailt IP for SwOs, although some of the later versions may also gra an IP from DHCP.

And any chance there is an old config on it? And also, you can view/set some of the SwOs config from RouterOS (the specific path escapes me at the moment . . . )

It's a new switch. Commissioned yesterday. The RJ45 ports do not work with swos. No port LED lights up.

Via a second switch I got a connection to the swos via the SFP+ port. All RJ45 interfaces are enabled but no port except the SFP+ ports work.

Does anyone have an idea how I get the ports up?

I still have a CSS316-24G+2S with swos 2.13 that works without problems.

Does a downgrade perhaps make sense?
