Not enough information to help you. Do you mean internet links and need a firewall with NAT? or local LAN gig links?

Two lan cables with internet
Currently we are doing it manually ... When one goes down we unplug it and plug the secondary active line ...

Both the links are from the same isp so no issues

I would think you'd need a router with multiple ethernet (inside) interfaces, if the two ISP's are providing different default gateways, a switch couldn't do this if one link went down.  How would a host know how to get to the internet if primary link went down,  in the Cisco world there was an ability to monitor links and apply secondary default gateway if the primary went down.

its just a secondary link from the isp

no gateway or ip is assigned to it ... fiber link with ethernet ...

You need a GUI configuration tool - have you looked at Arista gear?
