I have a Dell 6248 managed switch with 48 1 GB ports. I'm out of ports and would like to add an additional 48 1GB ports. The official Dell-Recommended solution is to get another 6248 and link the two with a 48GB fiber SFP+ uplink (might be using the wrong term here).
Is there a cheaper way to add 48 1GBe ports? For example, is there an unmanaged switch I could stack that's both theoretically and actually compatible?
Are there hidden compatibility issues if I try to stack with some other non-Dell managed switch?
