The 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.
For deployment convenience, M5300 series two rear I/O bays are pre-configured for stacking mode in factory default settings, allows for zero-touch stacking as soon as back connectivity is detected.
Copper, fiber can be mixed and matched for stacking interconnect.
One AX742 Stacking Kit per M5300 switch for local, dual ring topology
AX742 is a bundle: 2 CX4 I/O modules AX744 + 1 stacking CX4 cable (1m - 3.3 ft)
