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.
These attributes are fundamental to the core value of the 
software, enabling all Junos OS-powered products to be updated 
simultaneously with the same software release. All features are 
fully regression tested, making each new release a true superset 
of the previous version; customers can deploy the software 
with complete confidence that all existing capabilities will be 
maintained and operate in the same way.
Management Options
Up to four different system management options are available for 
the EX4500 Ethernet switches. 
The standard Junos OS command-line interface (CLI) offers the 
same granular management capabilities and scripting parameters 
found in any router powered by the Junos OS. 
1.  The EX4500 also includes the integrated Juniper Networks J-Web 
Software, an embedded web-based device manager that allows 
users to configure, monitor, troubleshoot, and perform system 
maintenance on individual switches via a browser-based graphical 
interface. 
2.  EX4500 performance, configuration, and fault data can also be 
exported to leading third-party management systems such as 
hP OpenView, IBM Tivoli, and Computer Associates Unicenter 
software, providing a complete, consolidated view of network 
operations.
3. The EX4500 is also supported by Juniper Networks Junos
®
 Space*, 
an open, programmable application platform for hosting  a 
comprehensive suite of network operational application tools that 
provide a smart, simple, and open approach for automating the 
deployment and operation of a Juniper infrastructure. 
4. 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. 
Features and Benefits
The EX4500 Ethernet switches include the following key features 
and benefits. 
High Performance
Each EX4500 supports 480 Gbps of bandwidth with 48 line-rate 
10 Gbps ports at all packet sizes or 14.88 Mpps per port at the 
minimum Ethernet frame size. 
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
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.
Small Footprint
The EX4500 supports up to 48 wire-speed 10GbE ports in a single 
2U platform.
