Connecting The Switches To Form The Stack Ring - Extreme Networks Summit X250e-24t Hardware Installation Manual

Installing Summit Family Switches
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
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.

Connecting the Switches to Form the Stack Ring

After you have installed the individual Summit switches, connect the switches together using the
stacking cables.
SummitStack 40G cables;
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.
NOTE
The connection recommendations in this section do not apply to Summit X650 series switches with installed
VIM1-SummitStack512 modules. For information about connecting the ports on the VIM1-SummitStack512
modules, see "Using the VIM1-SummitStack512 Module" on page
