So, I made a rookie mistake...CRS 317-1G-16S+ running SwOS 2.8. I managed to remove the MGMT (ethernet) port from the general setting for comms. I don't have access to the SFP's as they are 10G fiber connected to video equipment. I reset the system using the reset/boot. I can now access through webfig. System is now booting and running RouterOS 6.41. I am now in a loop of going to quick set and setting a static IP and selecting bridge mode, then going into webfig and going to system/routerboard/settings and selecting boot mode of SwOS. Reboot the system and I no longer have comm access.The only way back is to start the loop again. If anyone has a suggestion to correct a rookie mistake I would appreciate you greatly. Thank you in advance for your help.

Can't you perform factory reset according to instructions from wiki?
