Understanding Virtual Chassis Hardware Configuration
Virtual chassis is a feature in EX 4200 switches that allows you to interconnect two
or more EX 4200 switches, enabling them to operate as a unified single high
bandwidth switch. You can interconnect a maximum of 10 EX 4200 switches through
the dedicated 64-Gbps virtual chassis ports (VCPs) or the uplink module ports
configured as VCPs to form a virtual chassis. All EX 4200 switch models support
virtual chassis, and you can interconnect different models, offering a range of port
configurations, within the same virtual chassis.
The virtual chassis configuration includes designation of a master switch and a backup
switch, with all other switches in the configuration designated as "linecard" role
switches. Virtual chassis operation is managed through the master switch. Each
switch in the virtual chassis is assigned a unique identifier that is displayed on the
switch LCD.

Planning the Virtual Chassis
Before installing EX 4200 switches in a virtual chassis configuration, you must consider
the following factors:
■ The number of switches in the virtual chassis and location—You can interconnect
two to ten EX 4200 switches to form a virtual chassis. You can stack the switches
in a single rack or install them on multiple racks. For information on the size
and strength of racks, see “Rack Requirements and Specifications for an EX-series
Switch” on page 50. See “EX-series Switch Chassis Physical
Specifications” on page 7 for the dimensions and weights of the switch models.
■ Cabling requirements for virtual chassis—You can interconnect the EX 4200
switches in a virtual chassis configuration through virtual chassis ports (VCPs)
using the 0.5 meter long VCP cable supplied in the package. Depending on the
virtual chassis configurations you have, you might need cables of different lengths.
If you need longer cables, you can purchase them separately. The maximum
