Data Center and Campus Advantages
The EX4500 is an ideal switch for both data center and campus 
aggregation deployments. It offers an economical, power efficient 
and compact solution for aggregating 10GbE uplinks. Its feature 
set provides simplicity, scalability, availability, adaptability and 
modularity to your network.
Simple
Virtual Chassis on the EX4500 brings important simplification 
features to the campus aggregation layer. It eliminates the need 
for Spanning Tree, VRRP, complex routing, or VLAN configuration, 
therefore simplifying the management of the network. The 
EX4500 with Virtual Chassis reduces the number of virtual 
devices to manage and can even lead to a reduction in the number 
of network tiers. A single Virtual Chassis configuration can also 
span multiple nodes, reducing the need for uplinks and limiting the 
need for larger and more expensive nodes on superior tiers.
Scalable
With Juniper Networks Junos
®
 operating system shared across 
the entire EX Series platform and the EX4500 positioned in the 
top-of-rack and campus aggregation, the short learning curve 
enables you to quickly manage a complete architecture from one 
common set of instructions and one pane of glass. In addition, 
a single EX4500 can support up to 48 10GbE ports at line rate, 
enabling you to scale even in the most demanding environments. 
In addition, Virtual Chassis technology makes it easy to scale 
while reducing the complexity of managing a larger network; by 
adding switches to a Virtual Chassis configuration, it is possible 
to increase the number of ports without increasing the number of 
devices to manage. 
Available
The EX4500 offers redundant cooling and is available with 
redundant power supplies. A Virtual Chassis configuration – with 
several EX4500 switches – provides redundant routing engines 
and a network fabric. In addition, the EX4500 offers many other 
features that increase the availability of your network, including 
Open Shortest Path First (OSPF), Equal-cost multipath (ECMP), 
link aggregation group (LAG), links distributed across multiple 
slots, Graceful Routing Engine switchover (GRES), graceful 
protocol restart, and Quality of Service (QoS) to prioritize time-
sensitive data.
Adaptable and Modular
As your business grows, your needs change and your network needs 
to evolve. With its small form factor (2RU) and complete switch 
features (with a supervisor, up to 48 10GbE ports, available in one 
box), the EX4500 can be easily redeployed in different environments 
and physical layouts. The dual-speed interfaces of the EX4500 
enable you to transition your environments from GbE to 10GbE. The 
capacity of your EX4500 switch can easily be virtually increased by 
simply adding more switches to the Virtual Chassis configuration, 
without increasing the number of switches you have to manage. The 
modularity of an EX4500 with Virtual Chassis is clearly comparable 
to the adaptability of a modular switch.
