Management Options; Features And Benefits; Small Footprint; Additional Features - Juniper EX4500 Datasheet

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
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.
* Roadmap
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.
