 The cabling must crossover on the ports. For example, if ports 1
and 2 are the trunk, port 1 on one switch must crossover to port 2
on the second switch and port 2 must crossover to port 1.
 The twisted pair cables must be Category 6a or better.
 The maximum cable length is 100 meters (328 feet).
 The connections between twisted pair stacking ports must be
direct; there cannot be any intervening network devices, such as
switches, routers, or media converters.
An example of a stack trunk of twisted pair ports 1 and 2 is shown in
Figure 16.
