I'm adding a 2nd 3com 2920-SFP switch to our network, and was wondering how to connect them up in series(?) for more available user ports.
They have 4 SFP ports, and wanted to know if this was how its done.
usually you would use the SFP ports if you need every LAN port; however, a cheaper way is to just connect the two switches with a network cable to each other.
