The Juniper Networks EX4200 Ethernet Switch supports the Virtual Chassis flexible,
scaling switch solution. You can connect individual EX4200 switches together to form
one unit and manage the unit as a single chassis, called an EX4200 Virtual Chassis. Up
to ten EX4200 switches can be interconnected, providing up to a total of 480 access
ports. The available bandwidth increases as you include more members within the Virtual
Chassis configuration. See "Understanding the High-Speed Interconnection of the EX4200
Virtual Chassis Members" on page 902.
