Chapter 12: Building the Stack with AT-StackQS Cards

Introduction

160
This chapter explains how to build a stack of up to eight x930 Switches
with a stack trunk of 40Gbps transceivers in AT-StackQS Cards. There
are no configuration procedures. The stacking feature is enabled by
default on the switches and the ports on the AT-StackQS Cards are the
default trunk ports. To build the stack, you install the AT-StackQS Cards in
the switches, install 40Gbps transceivers, cable the transceiver ports, and
power on the switches either sequentially or simultaneously.
Here are the two procedures for powering on the stack with AT-StackQS
Cards as the stack trunk:
To control the assignment of the switch ID numbers yourself,

perform "Powering On the Switches Sequentially" on page 161.
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 163.
Caution
Do not change switch ID numbers after beginning to configure the
parameter settings of the stack. Otherwise, the stack might assign
configuration settings to the wrong switches the next time you reboot
or power on the stack.
For background information and guidelines, refer to "Trunks of AT-
StackQS Cards" on page 64.
