Virtual Chassis Module
Virtual Chassis modules are available for EX4500 and EX4550 switches. However,
installing a Victual 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.
