NOTE: Operating an EX4500 switch without the intraconnect module or the
Virtual Chassis module is not supported.
EX4500 switches running Junos OS Release 10.4R2 or later 10.4 releases will
not boot if you do not install the intraconnect module in the switch.
EX4500 switches running Junos OS Release 11.1R1 or later releases will not
boot if you install neither the intraconnect module nor the Virtual Chassis
module in the switch.
NOTE: The Virtual Chassis module is supported on EX4500 switches in Junos
OS Releases 11.1 and later.
The number of EX4500 switches that can be interconnected into a Virtual Chassis
composed exclusively of EX4500 switches depends on the Junos OS release running on
the switches. See "Understanding EX4200, EX4500, and EX4550 Virtual Chassis
Hardware Configurations" on page
EX4200, EX4500, and EX4550 switches can be connected together into the same Virtual
Chassis to form a mixed Virtual Chassis. The number of EX4200, EX4500, and EX4550
switches that can be interconnected into a mixed Virtual Chassis depends on the Junos
OS release running on the switches. See
Virtual Chassis Hardware Configurations" on page
You can use the following ports to configure an EX4500 switch in a Virtual Chassis
composed exclusively of EX4500 switches or in a mixed Virtual Chassis:
Dedicated VCPs on the Virtual Chassis module installed in the switch
SFP+ uplink module ports configured as VCPs
SFP+ fixed network ports configured as VCPs
For information about understanding and configuring Virtual Chassis, see Virtual Chassis
Feature Guide for EX2200, EX3300, EX4200, EX4500 and EX4550 Switches.
Optional uplink modules are available for EX4500 switches. You can install up to two
uplink modules in an EX4500 switch. Each uplink module provides four SFP+ ports for
connecting to core devices in a data center. You can install SFP or SFP+ transceivers in
these ports. You can also configure the uplink module ports as VCPs to form a Virtual
Chassis. For more information, see
EX4500 switches support both AC and DC power supplies. Each AC power supply is
available in two different airflow models, front-to-back and back-to-front. DC power
supplies are available only in the front-to-back airflow model.
