Extreme x250e-24t Installation Instruction

Summit Family Switches Hardware Installation Guide

If you intend to use the SummitStack feature, read this section before installing the set of Summit family 
switches that will be included in the SummitStack configuration. 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 

Depending on the switch model and type of stacking port, the bidirectional stacking link provides 
either 40 Gbps or 256 Gbps full duplex bandwidth. Stacking connections are made using stacking cables 
that are specific to the type of stacking port. These cables are available from Extreme Networks in 
lengths from 0.5 meter to 5 meters.
