Hello, I have installed vxrails G410 and they have 2 NICs + BMC port. Is my first time installing VXRail E460 Dell Hardware, When I checked the nics I see 4 network ports  + 1 iDrac. I am using 2 TOR switches. I am connecting one port to each switch. What should I do with the other 2 ports? what is the purpose of this 2 extra ports?
