Summit X650 Stacking

For Summit X650 native stacking, install VIM1 or VIM3 versatile interface module (VIM) into the rear of the switch. Link speeds and cable types vary depending on which VIM you selected. See Versatile Interface Modules for the Summit X650 Series Switches for more information about the VIMs supported.
