Extreme x250e-24t Installation Instruction

Summit Family Switches Hardware Installation Guide

●

For simplicity and ease of connecting the stacking cables, plan to designate the top switch in the 
physical stack as the stack master. This is the switch through which you will perform the initial stack 
configuration, using the console port.

●

For easier software configuration of the stack, connect the stacking cables in the order and 
arrangement shown in 

 and 

.

●

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 SummitStack 128G cable, Extreme Networks strongly recommends the 
use of cable management hardware to support the cables and provide strain relief at the connectors.

After you have installed the individual Summit switches, connect the switches together using the 
stacking cables. 

 show cable connections for two sample configurations using 

SummitStack 40G cables; 

 list the recommended order for connecting the stacking 

ports in these two examples. Connect Stack Port 2 on one switch to Stack Port 1 on the switch with the 
next higher slot number. 

Although you can connect the switches in any order, connecting them as shown in these examples will 
produce better predictability and easier software configuration. It is essential to create an unbroken data 
path through all the switches in the stack.
