STACKING DELL POWERCONNECT 6200 SERIES

SCENARIO 2

Consider the same example with a four-unit stack connected in daisy-chain fashion.

Switch 1

Switch 2

Switch 3 Master

Switch 4

If the links between Switch1/Switch4 and Switch2/Switch3 are removed, the stack is split into

two different stacks with switches 1 and 2 in one stack and switches 3 and 4 in another.

The Master unit for each stack is determined by the following criteria:

• Switch 3 is already a Master, so it will continue to be the Master unit for units 3 and 4.

• None of the units in Stack 1 (units 1 and 2) are Master, so the election process will

start on these two units. Subsequently either switch 1 or 2 will come-up as a Master

based on the items:

1. The unit with the highest administrative preference level becomes the Master.

2. If the administrative preference levels are the same, the unit with the highest

hardware preference level becomes the Master.

3. If the administrative and hardware preference levels are the same, the unit with

the highest base MAC address becomes the Master.

In this specific example, there will not be any change in the configuration in the Stack 2. Stack

1 will come up with the previously saved configuration on the new Master elected.
