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
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.
