3Com switch Stacking

Hello 3Com switch Experts
I have a 3Com 4200G 48-port switch which I am planning to stack with another of the same switch to make them a core switch. What would be the best way to stack them? Use link aggregation using 2 1Gig ports, use SFP or use Xenpak to connect the 10-gig slot on the back?
I will have about another 4 10/100 switches connecting to this core switch, all 3Com.

Best way is using Xenpak. This will simply add more ports to the "same" switch. Uplink will limit the traffic, since the switch has a higher capacity than 2 GB.

How about stacking it with SFP?

Product description tells me SFP does only provide you with a 1GB-Uplink. So this would be an option for connecting long-distance. So Xenpak ist best, trunking/aggregation coming next.

Basically these switches will be on the same rack. Distance isn't a factor here. Another question will be what is the purpose of using a 1000BaseT SFP when I can get the same speed with any of the ports.

You can't have long distance (> 100 m) without using fiber uplinks. That's what SFP is for.
