- Adds a 24Gbps Stacking connectivity to the GSM7328S and GSM7352S. - Modular design lowers costs while maximizing flexibility. - Non-blocking wire-speed performance. - Configured in a resilient ring topology, delivers 48Gbps of stacking bandwidth. AX742 Stacking Kit is cost-effective preferred method for local Virtual Chassis Stacking using both rear I/O bays. When some switches are distant, affordable SFP+ (AX743) and 10GBase-T (AX745) I/O modules allow for fiber or copper distant connections, still leveraging rear bays zero-touch stacking functionality.
