The upper power socket on the Summit Virtual Chassis provides the AC source for
backup power for the upper switch; the lower power socket provides the AC source for
backup power for the lower switch.

ONFIGURATIONS
The following two types of Summit Virtual Chassis configurations are supported:
•
Single Virtual Chassis stack
•
Parallel Virtual Chassis stack (using two or four Summit Virtual Chassis)
A Virtual Chassis stack is any valid Virtual Chassis configuration that includes the
Summit Virtual Chassis and Summit switches. A parallel Virtual Chassis stack can
consist of two or four Summit Virtual Chassis. Multiple stacks can be combined using
traditional bridging and routing system design elements.
A single Summit switch can be connected to multiple Summit Virtual Chassis
units. However, you can have only one connection between any one Summit
switch and any one Summit Virtual Chassis. In addition, a Summit Virtual
Chassis cannot connect directly to another Summit Virtual Chassis.
You cannot use the redundant Gigabit Ethernet port to connect to a Summit
Virtual Chassis.

In a single Virtual Chassis stack, one Summit Virtual Chassis can be connected to a
maximum of eight Summit switches. A single Virtual Chassis stack is shown in Figure 6.
