Because the trunk cannot have more than two 100Gbps ports per
switch, stacks of three or four switches can have only one link
between switches.
Stacks can have any combination of x950-28XSQ, x950-28XTQm,
or/and x950-52XSQ switches.
Figure 32 illustrates stacks of two, three, and four switches, with
ports 33, 37, 57and 61 and 100Gbps links as the trunks.
