Planning EX4200, EX4500, and EX4550 Virtual Chassis
Before interconnecting EX4200, EX4500, and EX4550 switches in a Virtual Chassis
configuration:
•
Verify that the rack in which you will install the switches meets the requirements
described in “Rack Requirements for EX4200 Switches” on page 69, Rack Requirements
for EX4500 Switches, and Rack Requirements for EX4550 Switches. You can mount
the switches in a Virtual Chassis on a single rack or on multiple racks.
•
Verify that the installation site meets the power requirements of the switches in a
Virtual Chassis.
•
Verify that you have installed a Virtual Chassis module in an EX4500 switch running
Junos OS releases earlier than Release 11.4R1. The Virtual Chassis module must be
installed in an EX4500 switch to form a Virtual Chassis.
Table55 on page 146 describes the VirtualChassiscomponentsand the Junos OSrelease
running on switches that you need to consider when you plan your EX4200, EX4500,
and EX4550 Virtual Chassis configuration.
