Router switch failure scenario

I been looking into upgrading a site after the lone Mikrotik router “failed” this morning and needed a power reset. I have come up with a two router solution using VRRP

My question is how independent of the software is the hardware switch portion of the router?

If I have two ports connected to the switch portion of the Mikrotik (one is a slave of the other) and the OS fails, will the switch portion keep working until the router gets rebooted?
