Chapter 15: Building a Stack
288 Section III: Building a Stack with VCStack Plus
Before You Begin
Please review the following information before you begin to configure the
switches for stacking:
 You must perform the procedures in the order presented here.
 You should configure only one chassis at a time.
 The procedures are the same regardless of whether a chassis has
one or two controller cards.
Note
This procedure requires power cycling or resetting the switches.
Some network traffic may be lost if the units are already connected
to an active network.
The procedures assume the following:
 All hardware components have been installed in the two switches,
including Ethernet line cards, controller cards, and power supplies.
For installation instructions, refer to the previous chapters in this
guide.
 The switches are powered on. For instructions, refer to Chapter 9,
“Powering On the Chassis” on page 171.
 You verified the operations of the chassis with the procedures in
Chapter 10, “Verifying the Hardware Operations of the Chassis” on
page 209.
 There are no transceivers in the SFP+ slots on the AT-
SBx81CFC960 Controller Fabric Cards. If there are transceivers in
the slots, you should remove them before performing the
procedure.
A stack requires these additional items:
 Two VCStack Plus feature licenses: Each chassis must have its
own license. For more information, refer to “VCStack Plus Feature
License” on page 280.

Eight AT-Stack transceivers if each switch in the stack has one
controller card or sixteen transceivers if each switch has two
controller cards. The transceivers form the trunk that connects the
two switches together. For more information, refer to “Stack Trunk”
on page 275.
