We currently have two C3750G-24PS-S switches stacking together using the stack cable connecting in the back. We want to expand to a stack of four switches but since the C3750G is end of life so we want to buy two C3750X-24T-S (we don't need PoE at this site) and hope to stack these two new C3750X-24T-S switches onto the current stack of two old C3750G-24PS-S. Can we do that? <br />
<br />
Thanks for your help.

Can I stack two new C3750X-24 switches onto a current stack of two older C3750G-24 switches?

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
