Stack Management Overview
A stack consists of up to eight units, with support for up to 400 network ports.
Unit 1 usually acts as the stack master and Unit 2 is the backup master. All
other units act as slaves.
The entire stack, without regard to the stack topology or the number of units
in the stack, can be managed as a single switch.
For more information about stacking, see "Stacking Overview" on page 43.
The stacking pages described in this section enable the following actions:
• Switching from the Master unit to the Backup Master unit
• Changing unit IDs
• Viewing hardware and software versions on each unit
• Resetting either a unit or all the units in the stack
• Setting the Location LED on a unit(s)
