Managing Switch Stacks

The purpose of this section is to collect notes on recommended procedures and expected behavior 
of stacked FSM7328S/FSM7352S. Procedures addressed initially are listed below. 

•

Initial installation and power-up of a stack. 

•

Removing a unit from the stack

•

Adding a unit to an operating stack

•

Replacing a stack member with a new unit

•

Renumbering stack members

•

Moving the master to a different unit in the stack

•

Removing a master unit from an operating stack

•

Merging two operational stacks

•

Preconfiguration

•

Upgrading firmware

•

Migration of configuration with a firmware upgrade

Stack master election specifically determined by 
the MAC address
• Assuming that both stack members have the 

same priority value and software image, restart 
both stack members at the same time.

The stack member with the higher MAC address is 
elected stack master.

Add a stack member
• Power off the new switch
• Through their stacking ports, connect the new 

switch to a powered-on switch stack.

• Power on the new switch.

The stack master is retained. The new switch is 
added to the switch stack.

Stack master failure
• Remove (or power off) the stack master.

Based on "Stack Master Election and Re-Election" 
on page 5, one of the remaining stack members 
becomes the new stack master. All other stack 
members in the stack remain as stack members 
and do not reboot.
