Chapter 8: Building Stacks with SFP+ Ports S1 and S2

Introduction

108
This chapter explains how to build the stack with SFP+ ports S1 and S2 as
the stack trunk. There are no configuration procedures. The stacking
feature is enabled by default on the switches and the SFP+ ports are the
default trunk ports. To build the stack, you cable the trunk ports and power
on the switches, either sequentially or simultaneously.
As explained in the following procedures, the switches are assigned ID
numbers based on how you power on the devices. The switches display
their ID numbers on the ID LEDs on the front panels and store them in
their stack configuration files to identify their parameter settings. As
explained in "Specifying Ports in the Command Line Interface" on
page 56, you use the ID numbers to identify the switches when you
configure them with the command line interface in the AlliedWare Plus
management software. They retain their ID numbers even when you
power off or reset the stack.
Here are the two procedures for powering on the stack with SFP+ ports S1
and S2 as the stack trunk:
To control the assignment of the switch ID numbers yourself,

perform "Powering On the Switches Sequentially" on page 109.
The numbers are assigned in the order in which you power on the
units.
To have the switches assign the ID numbers automatically, perform

"Powering On the Switches Simultaneously" on page 111.
Caution
Do not change the switch ID numbers after configuring the
parameter settings of the stack. Otherwise, the stack might assign
configuration settings to the wrong switches.
Note
To use the Multi-Gigabit copper ports as the stack trunk instead,
refer to Chapter 9, "Building Stacks with Multi-Gigabit Copper Ports"
on page 117. For background information, refer to "Multi-Gigabit
Copper Ports" on page 47.
