Configuration tips for building a stack using the automatic setup process
Remember the following tips when using the automatic setup process for building a stack:
• If a new unit configuration matches other unit configurations, the active controller gives this unit the
lowest sequential ID. For example, in a stack configuration that contains eight FCX624
configurations, but only units 1, 4 and 8 are currently active, if you place a new FCX624 unit
between units 4 and 8, the new unit will be assigned unit ID 5. This unit assignment occurs
because unit 5 is the lowest sequential ID and comes directly after active unit 4 even though it
might match unused inactive unit IDs 2, 3, 5, 6, and 7.
• In a ring topology, the same new unit might assume either ID if either direction produces sequential
IDs. For example, in a four-member stack where IDs 2 and 4 are reserved, a new unit could
assume either I2 or ID 4 because either ID 1,2,3 or 1, 3, 4 is sequential.
Scenario 3 - Three-member traditional stack in a ring topology using
the manual configuration process
Complete the following steps to configure a three-member traditional stack in a ring topology using the
manual configuration process.
1. Power on the devices. Do not connect the stacking cables at this point.
2. Assign a priority of 255 to unit 1, and a priority of 240 to unit 3 using the priority command. You do
not have to assign a priority to the third device. Enter the stack enable command on each device.
In this example, device 1 will be the active controller and device 2 will be the standby controller.

device(config)# stack unit 1
