Are you reporting that Cisco no longer answers questions on their gear? Just last year on a job they were still answering pre-sales questions.
Hello,
I will install 6 CISCO SG220-26P POE with 2 SFP Switches in 3 separated IT Rooms so 2 switches for each room, I would like to link all the switches in the same network using the SFP, in top of them a CISCO ASA 5512-X Firewall linked to the first switch with a CAT-6 RJ45 Cable, my question is this architecture like the attached image good and stable or I will have a networking troubles in the future? and is linking the (S3 , S4) and (S5 , S6) using an SFP a good solution? or its better to use RJ45 CAT 6 Cable?
