Hi everybody,
I have a CCR-116-12s-1s+ (Note this board dont have any ethernet port).

A couple of months ago this device keep rebooting all the time.
Now I was trying to recover using USB to Serial cable.
I was able to load the menu, but I'm afraid netinstall only get ready when boot is over Ethernet, and Not like this devicep; (with Serial port only).
I wondering if this device is an exception, I think all boards could have 1 ethernet port at least.
I tried using another mikrotik with and using 2 SFP, but it not seems to get link.
There is a known procedure on this like of scenarios?.
thank you so much

From manual:
https://help.mikrotik.com/docs/pages/vi ... d=19136595

Extension Slots and Ports
Twelve SFP cages
One SFP+ cage
micro USB type AB
RS232 serial port
Etherboot / Netinstall is available on port 12. One RJ45 SFP to Ethernet module is included for management connectivity.

So you DO have an ether port available for netinstall.

Thanks @Holvoetn, Your answer give me a light of hope.
I've just tried using port 12 with a SFP module (and another mikrotik y the other side) but I haven't lucky.
But I must got (like u suggest) One RJ45 SFP to Ethernet module converter to try again.
Best!
