Junos Operating System
The EX4500 runs the same Juniper Networks Junos
®
operating
system that is used by other EX Series Ethernet Switches, as
well as all Juniper Networks routers and Juniper Networks SrX
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.

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.

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.

in the data center, using Virtual chassis technology at the top of
rack or end of row to aggregate servers in the data center provides
flexibility in the deployment of uplinks. rather than requiring
redundant links for each physical switch to ensure high availability,
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.

Management Options
Up to four different system management options are available for
the EX4500 Ethernet switches.

2. 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.

3. 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.

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.
