Planning for Stacking

Summit "e" series switches can be installed in a stacked configuration that is managed as one switching
entity. The Summit 200 and 300 series switches use the Gigabit Ethernet ports on the front of the switch
as the stacking connectors for interconnecting to other switches in a stacked configuration. The Summit
400 series switches use dedicated stacking ports on the back of the switch. When you plan a stacked
configuration, 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 switches
in a stack, the stack will not come up. For more information about stack operation, see the
ExtremeWare User Guide and ExtremeWare Command Reference Guide.

Maximum Switches in a Stack

Although software supports up to eight switches in a stack, certain hardware restrictions do not allow
stacking eight units of some types. Each switch type is assigned a platform weight or slot budget to be
used in determining the total number of switches allowed in the stack. The Summit 400 series switches
also have an assigned platform weight for installed 10-gigabit dual uplink ports (Summit XEN or
XGM-2xn Option Card). Table 5 lists the platform weights.
