Placing Summit Family Switches for Stacked Operation

This section summarizes the recommended best practices for installing Summit switches for a SummitStack configuration. For detailed information about how to configure and manage the stack and how a stack operates, refer to the Extre me XOS Conce pts Guide .

When you install switches for a SummitStack configuration, follow these recommendations:

●Use the shortest possible stacking cables to connect the switches in the stack; this reduces the likelihood that the stacking cables might be accidentally damaged or disconnected. Stacking cables are available in lengths from 0.3 meters to 5 meters (see Table 19).

●When possible, place all switches for the stack in the same rack or in adjacent racks; this facilitates using shorter stacking cables.

●The stack master is the switch through which you will perform the initial stack configuration, using the console port. For simplicity and ease of connecting the stacking cables, plan to designate the top switch in a vertical physical stack as the stack master. If switches are installed in several adjacent racks, place the stack master at one end of the row.

●Physically locate the intended master and backup nodes adjacent to each other, and connect these switches directly to each other.

●For easier software configuration of the stack, connect the stacking cables in the order and arrangement shown in the tables that accompany the examples.

●On the stack master switch, connect the Ethernet management port to your management network.

●To provide management access to the stack in case of a failure in the master switch, connect all switches that will participate in redundancy to your management network using the Ethernet management port on each switch.

●Because of the weight of the cable, Extreme Networks strongly recommends the use of cable management hardware to support the cables and provide strain relief at the connectors when you use the SummitStack 128G cable, SummitStack 64G cable, or SummitStack 128G/64G cable (see “Connecting Stacking Cables” on page 108).
