The Summit 200 and 300 series switches use the Gigabit Ethernet ports on the front of the switchas the stacking connectors for interconnecting to other switches in a stacked configuration. The Summit400 series switches use dedicated stacking ports on the back of the switch. When you plan a stackedconfiguration, you must take into account:• The number and types of switches in the stack.• The placement of switches in the stack. Summit 400 series switches should be adjacent to each other.• Software versions running on the switch. If the major version number is different between switchesin a stack, the stack will not come up. For more information about stack operation, see theExtremeWare User Guide and ExtremeWare Command Reference Guide.Maximum Switches in a StackAlthough software supports up to eight switches in a stack, certain hardware restrictions do not allowstacking eight units of some types. Each switch type is assigned a platform weight or slot budget to beused in determining the total number of switches allowed in the stack. The Summit 400 series switchesalso have an assigned platform weight for installed 10-gigabit dual uplink ports (Summit XEN orXGM-2xn Option Card). Table 5 lists the platform weights.Extreme Networks Consolidated "e" and "i" Series Hardware Installation Guide 41
