Many switches, including most Summit X250e, X450a, and X450e series models, have standard stacking ports built in. The stacking ports are found on the rear of the switch.
Use any standard SummitStack stacking cables to connect the stacking ports.
The stacking-support option is disabled by default for Summit X250e, X450a, and X450e switches. For more information, see Enabling and Disabling the Stacking-Support Option.
The stacking port selection option, which allows you to choose between native and alternate ports, is enabled by default for X450a and X450e switches. For more information, see Selecting Native and Alternate Stacking Ports.
To use alternate stacking on a Summit X450a or X450e switch, you must install an XGM2-2xf, XGM2-2xn, XGM2-2sf, or XGM2-2bt port option card to add 10-Gbps ports to the switch.
