Netgear GS752TS stacking

Hello

How do I stack a set of GS752TS'?

There is no longer an HDMI port so I am presuming that they do not stack in the original 48GBps way. Do I have to stack with 4 x 1GBps ports?

Is that actually stacking though as I could've just bought some switches with 2 x 10GBps ports and made a LAG that would be much better..?

Yes you must use a Netgear set of modules or a complete Netgear fibre cable set (or two) and the stack will automatically configure itself and even update the firmware so that both switches are the same.
