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
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
"Connecting the Switches to Form the Stack Ring" on page 101
switches from different Summit series.
