The Physical 
Stack
Depending on the switch types used, a stack can comprise from 2 to 8 
individual stack members interconnected via high speed stacking links. A 
stack always has a primary stack member called the stack master, and 
can contain up to 7 other stack members. For information about VCStack 
stacking modules available and cable specifications, see “Connecting 
switches into a stack” on page 67
 for more information.
Two Switch Stack Configuration
This configuration, shown in Figure 33,
 
uses two switches that are 
connected back to back via two high-speed stacking links. In this 
configuration the stack can still function using only a single high speed 
link. Note that stacking ports labeled 1 must connect to stacking ports 
labeled 2. Also, in this example the switches have AT-StackXG stacking 
modules installed.
