Stacking Summit Family Switches

A stack consists of a group of up to eight Summit switches that are connected together using stacking cables to form a connected ring, as shown in Figure 69. The stack can combine any Summit series switches that include support for stacking, as long as you follow port compatibility and cabling recommendations. See “Placing Summit Family Switches for Stacked Operation” on page 100 and “Connecting the Switches to Form the Stack Ring” on page 101 for more information about combining switches from different Summit series.
