3 Managing OmniSwitch
6800 Series Stacks
In addition to working as individual stand-alone switches, OmniSwitch 6800 Series switches can also be
linked together to work as a single virtual chassis known as a stack. With stacks, users can easily expand
their switching capacity simply by adding additional switches to the stack. In addition, stacks provide
enhanced resiliency and redundancy features. For more information, refer to page 3-2.
Note. See Chapter 2, “OmniSwitch 6800 Series Chassis and Hardware Components,” for information on
managing OmniSwitch 6800 Series switches in a stand-alone configuration.
