If the switch with the lowest MAC address happens to be the bottom-most module in the stack, slot
numbering will not resume from the top of the stack. Instead, the system software will select the second-
ary module using the standard method (i.e., the switch connected to the primary's stacking port A), then
continue to number the stack from the bottom up. This intuitive slot assignment provides the cleanest and
most manageable stack topology. Refer to the diagram below for more information:
Slot 4 - Idle
Slot 3 - Idle
Slot 2 - Secondary

address in the stack.) This switch is
automatically assigned slot number 1.
The switch immediately above is con-
nected to the primary switch's stacking
port A and, as a result, is assigned the
secondary management role and given
slot number 2.
The system software then sequen-
tially assigns slot numbers up the
stack. In other words, the switch
