we've got three HP 3500 (48 port) switches and three 3Com 2948-SFP switches. At the moment, the way they're connected is with ethernet ports and like a chain. So switch 1 is connected to switch 2, switch 2 to switch 3 and so on. All of the switches each have some spare ports left on them (around 6 ports left).
I've been asked to look into using copper links between the switches, so for switch 1 to get connected to switches 2,3. Then for switch 2 to get connected to switch 4,5,6.
Is this worth it? Are there any changes I have to make on the switch itself or can I just get copper wires and plug them into the special ports provided?
