SummitStack ports are integrated into the rear panel of X250e, X440, X450, X450a, and X450e series switches.
The X460-G2 accommodates the VIM-2ss SummitStack module, which provides SummitStack ports.
The X460, X480, and X650 also accommodate VIMs or stacking modules that provide SummitStack ports.
The examples in the following sections show various physical stacking arrangements: all switches in a single rack, switches in two adjacent racks, and switches at the tops of several racks in a row.
