EX4500 Switches Hardware Overview
Juniper Networks EX4500 Ethernet Switches provide high-density 10-gigabit ports for
aggregation layerand data center top-of-rack deployments,and provideoptions for data
center optimized airflow (hot aisle/cold aisle). You can configure EX4500 switches in a
Virtual Chassis, or in a mixed Virtual Chassis with EX4200 switches or EX4550 switches
or both, in a total of up to 10 members.
Software
You can manage EX4500 switches using the same interfaces that you use for managing
other devices running Juniper Networks Junos operating system (Junos OS)—the
command-line interface (CLI) and the J-Web graphical interface.

Juniper Networks EX Series Ethernet Switches run Junos OS, which provides Layer 2 and
Layer 3 switching, routing, and security services. The same Junos OS code base that runs
on EX Series switches also runs on all Juniper Networks M Series, MX Series, and T Series
routers, and SRX Series Services Gateways. For information about installing software on
your switch, see Software Installation on EX Series Switches.

Complete Hardware Guide for EX4500 Ethernet Switches
EX4500 Switches First View
EX4500 switches provide connectivity for high-density 10-Gigabit Ethernet data center
top-of-rack and aggregation deployments. Typically, EX4500 switches are used in data
centers where they can be positioned as the top device in a rack to provide connectivity
for all devices in the rack.
The EX4500 switch is 2 rack units (2 U) in size. Each EX4500 switch is designed to
optimize rack space utilization and cabling. See Figure 1 on page 4, Figure 2 on page 4,
and Figure 3 on page 5.
NOTE: The side of the switch where the networkports are locatedis the front
of the switch.
Figure 1: EX4500 Switch Front
Figure 2: EX4500 Switch Rear with Intraconnect Module Installed
Copyright © 2015, Juniper Networks, Inc.4
Chapter 1: EX4500 Switch Overview
Figure 3: EX4500 Switch Rear with Virtual Chassis Module Installed
EX4500 switches are availablein models with either front-toback airflowor back-to-front
airflow and hardware that either supports or does not support Data Center Bridging
(DCB), also known as Converged Enhanced Ethernet (CEE). See “EX4500 Switch Models”
on page 7. All eight models provide40 wire-speed10-gigabit small form-factorpluggable
(SFP+) network ports that can house either 1-Gigabit Ethernet transceivers or 10-Gigabit
Ethernet transceivers. All models support two optional high-speed uplink modules.
To provide carrier-class reliability, EX4500 switches include:
•
Dual redundant, load-sharingpower supplies that are hot-insertableand hot-removable
field-replaceable units.
•
An FRU fan tray with five fans. The switch remains operational if a single fan fails.
•
RedundantRouting Engines in a Virtual Chassis configuration. This redundancy enables
graceful Routing Engine switchover (GRES).
•
Junos OS with its modular design that enables failed system processes to gracefully
restart.
Intraconnect Module and Virtual Chassis Module
EX4500 switches ship with either the intraconnect module or the Virtual Chassis module
preinstalled in the switch. Only one of the modules can be installed on the rear side of
the switch chassis at a time. Both modules are offline FRUs.
•
Intraconnect module—The intraconnect module helps the switch achieve line rate on
all its ports. See “Intraconnect Module in EX4500 Switches” on page 38.
•
Virtual Chassis module—The Virtual Chassis module has two dedicated Virtual Chassis
ports (VCPs) that can be used to interconnect the EX4500 switch with EX4200
switches,EX4500 switches, or EX4550 switches to form a Virtual Chassis. See “Virtual
Chassis Module in EX4500 Switches” on page 39.
5Copyright © 2015, Juniper Networks, Inc.
Complete Hardware Guide for EX4500 Ethernet Switches
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 VirtualChassis module is supported on EX4500switches in Junos
OS Releases 11.1 and later.
Virtual Chassis
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 103.
Uplink Modules
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 “Understanding EX4200, EX4500, and EX4550
Virtual Chassis Hardware Configurations” on page 103.
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 VirtualChassis, see EX2200, EX3300,
EX4200, EX4500 and EX4550 Virtual Chassis.
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 “Uplink Modules in EX4500 Switches” on page 36.
Power Supplies
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.
Copyright © 2015, Juniper Networks, Inc.6
Chapter 1: EX4500 Switch Overview
EX4500 switches ship with one AC or DC power supply installed. Youcan install a second
AC or DC power supply in your EX4500 switch. See “AC Power Supply in EX4500
Switches” on page 27 and “DC Power Supply in EX4500 Switches” on page 30.
CAUTION: Mixing different types (AC and DC) of power supplies or power
supplies with front-to-back and back-to-front airflow in the same chassis is
not supported.

model number of switches thatdo not support Virtual Chassis indicates that the switch
does not support DCB.
NOTE: All models of EX4500 switches that support Virtual Chassis
(switchesthat have the label VIRTUALCHASSIS on the front panel) support
DCB even though their model numbers do not have a C appended.
