Virtual Chassis Module

Virtual Chassis modules are available for EX4500 and EX4550 switches. However, installing a Virtual
Chassis module is not mandatory for using these switches in a Virtual Chassis configuration.
NOTE: On EX4500 switches that are running Junos OS releases earlier than Release 11.4R1,
you must install a Virtual Chassis module for using the switch in a Virtual Chassis configuration.
Starting with Release 11.4R1, you can use uplink port connections to interconnect EX4500
member switches into a Virtual Chassis.
