EX4500 Ethernet
Product Overview
The Juniper Networks EX4500 line
of Ethernet switches delivers a
scalable, high-performance platform
for supporting high-density 1 gigabit
per second (Gpbs) and 10 Gbps data
Product Description
Featuring 48 wire-speed 10-Gigabit Ethernet (10GbE) ports in a two rack unit (2U) platform,
the Juniper Networks® EX4500 Ethernet Switch delivers Layer 2 and Layer 3 connectivity to
networked devices such as servers and other switches. The EX4500 base switch provides
40 fixed 10GbE pluggable ports that can also support GbE connectors for added flexibility.
Two optional high-speed uplink modules offer four additional 10GbE small form-factor
pluggable transceiver (SFP+) ports each for connecting to upstream devices.

complement the Juniper Networks EX Series Ethernet Switch product family: the Juniper
Networks EX2200 line and EX3200 line designed for low-density access deployments;
the EX4200 line designed for data center and campus GbE access and aggregation
deployments; and the EX8200 line of Ethernet switches designed for data center and
campus core and aggregation environments.
Data Center Deployments
The EX4500 Ethernet Switch is designed for demanding data center applications where
high performance, high availability, and energy efficiency are key requirements (see Figure 1).
Operating at wire speed, the EX4500 switches deliver 714 Mpps throughput and a data rate of
960 Gbps (full duplex) for both Layer 2 and Layer 3 protocols.
Flexible deployment options enable the EX4500 to support back-to-front and front-to-back
cooling, which ensures consistency with server designs for hot and cold aisle deployments.
Front- and rear-facing configuration options ensure closer proximity to server ports, optimizing
performance and keeping cable lengths short and manageable. The EX4500 is also
environmentally conscious, drawing less than eight watts per port under maximum load.

Series Services Gateways. By utilizing a common operating
system, Juniper Networks delivers a consistent implementation
and operation of control plane features across all products.
To maintain that consistency, Junos OS adheres to a highly
disciplined development process that uses a single source code,
follows a single quarterly release train, and employs a highly
available modular architecture that prevents isolated failures from
bringing down an entire system.

Virtual Chassis Technology
The EX4500 is designed to support Juniper Networks’
unique Virtual Chassis technology*, which enables multiple
interconnected switches to operate as a single, logical device
with a single IP address. When deployed in a Virtual Chassis
configuration, the EX4500 switches will be connected over a
128 Gbps backplane using Virtual Chassis interconnect cables.
Interconnected switches are monitored and managed as a
single device, enabling enterprises to separate physical topology
from logical groupings of endpoints and allowing more efficient
resource utilization.
that provide a smart, simple, and open approach for automating
the deployment and operation of a Juniper infrastructure.
Explicitly designed to allow partners and customers to build and
deploy smart, simple, and easy-to-use applications, Junos Space
provides multiple management and infrastructure applications
for managing Juniper resources and assets, including inventory
management, device and interface configuration, automated
software management and deployment, and event-driven fault
management. These Junos Space applications offer predefined
automation schemes and best practice templates to enable
rapid and accurate deployments.

High Performance
redundant links are only needed for each Virtual Chassis
group. In the future, EX4500 and EX4200 switches may be
combined within a single Virtual Chassis configuration to support
environments where both GbE and 10GbE servers are present.
Each EX4500 supports 10 Gbps of bandwidth with 14.88 Mpps per
port on all 48 ports at all packet sizes.
High Availability
The EX4500 switches offer dual internal load sharing AC power
supplies, and redundant variable-speed fans as standard features,
protecting the switch from a single power supply or fan failure. DC
power options will be available in the future.

Energy Efficient
EX4500 10GbE Ethernet Switch Specifications
Consuming less than eight watts per 10GbE interface, the EX4500
offers a low power solution for 10GbE top-of-rack, end-of-row,
and aggregation deployments. The EX4500 switches also improve
cooling efficiency with redundant variable-speed fans that
automatically adjust their speed based on existing conditions to
reduce power consumption.
