Installing the Switch
Power-On Sequence for Switch Stacks
Consider these guidelines before you power on the switches in a stack:
•
The sequence in which the switches are first powered on might affect the switch that becomes the
stack master.
•
If you want a particular switch to be the stack master, power on that switch first. This switch
becomes the stack master and remains the stack master until a master re-election. After 2 minutes,
power on the other stack switches.
•
If you have no preference as to which switch becomes the stack master, power on all the switches in
the stack within a 1-minute timeframe. These switches participate in the stack master election.
Switches powered on after the 1-minute timeframe do not participate in the election.
•
Power off a switch before you add it to or remove it from an existing switch stack.
For conditions that can cause a stack master re-election or to manually elect the stack master, see the
“Managing Switch Stacks” chapter in the switch software configuration guide on Cisco.com.
