Managing OmniSwitch 6350 Stacks
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
secondary 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
Slot 1 - Primary

Dynamic Slot Numbering Example 2

In this example, the bottom switch is elected
the primary management module for the
stack. (It can be assumed that this switch has
the lowest MAC address in the stack.) This
switch is automatically assigned slot number
1.
The switch immediately above is connected to
the primary switch's stacking port A and, as
a result, is assigned the secondary manage-
ment role and given slot number 2.
The system software then sequentially assigns
slot numbers up the stack. In other words, the
switch immediately above slot 2 is assigned the
slot number 3; the switch immediately above
slot 3 is assigned the slot number 4, and so on.
This default procedure ensures the most ordered
and manageable stack topology out of the box.
