CRS30x Switch OS

Hi,

How do I switch from RouterOS (6.49) to SwitchOS on CRS30x devices?

I’ve tried setting the devices (CRS309 & CRS305) to boot to swOS (2.13) through winbox, however when I reboot the devices they ‘disappear’.
By disappear I mean that neither winbox or nmap can find them.

System → swOS → Address Acquisition DHCP with Fallback → fallback address 192.168.88.2
System → routerBoard → Settings → Boot swOS
System → reboot

Device is connected directly to laptop no other switches or routers in the way.
Only way I can connect to the device again is to press the reset button and go back to routerOS
