Switch Stacks

Managed Switches 
Stack Members
A switch stack can include up to eight stack members connected through their stack ports. A 
switch stack always includes one stack master.
A standalone switch is a switch stack with one stack member that also operates as the stack 
master. You can connect one standalone switch to another to create a switch stack 
containing two stack members, with one of them being the stack master. You can connect 
standalone switches to an existing switch stack to increase the stack membership.
The operation of the switch stack continues uninterrupted during membership changes 
unless you remove the stack master or you add powered-on standalone switches or switch 
stacks.
Stack Member Numbers
A stack member number (1 to 8) identifies each member in the switch stack. The member 
number also determines the interface-level configuration that a stack member uses. You can 
display the stack member number by issuing the show switch user EXEC command.
A new, out-of-the-box switch (one that did not join a switch stack or was not manually 
assigned a stack member number) ships with a default stack member number of 1. When the 
switch joins a switch stack, the default stack member number of the switch changes to the 
lowest available member number in the stack.
Stack members in the same switch stack cannot be assigned the same stack member 
number. Every stack member, including a standalone switch, retains its member number until 
you manually change the number or unless the number is already being used by another 
member in the stack. Fore more information, see 
Stack Member Priority Values
You can change a stack member priority. This is useful if you want to change the master 
of the stack. To change the stack member priority, issue the switch unit priority 
value
 command in the global config mode.
Install and Power-up a Stack
Many switch models include a Hardware Installation Guide with information about rack 
mounting and stack cabling.
