Carrier-Class Operating System
The EX4200 runs on Junos OS, the same operating system
software used by Juniper Networks routers to power the world’s
largest and most complex networks.
software used by Juniper Networks routers to power the world’s
largest and most complex networks.
By utilizing a common operating system, Juniper 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
utilizes a single source code, follows a single quarterly release
train, and employs a highly available modular architecture that
prevents isolated failures from bringing an entire system down.

train, and employs a highly available modular architecture that

These attributes are fundamental to the core value of the
software, enabling all products powered by Junos OS 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.

Converged Networks
The EX4200 line of Ethernet switches provide the highest levels
of availability for the most demanding converged data, voice
and video environments, delivering the most reliable platform for
unifying enterprise communications.

By providing Class 3 PoE with 15.4 watts on some or all ports to
power voice over IP (VoIP) telephones, closed-circuit security
cameras, wireless access points, and other IP-enabled devices,
the EX4200 delivers a future-proofed solution for converging
disparate networks onto a single IP infrastructure.

cameras, wireless access points, and other IP-enabled devices,
the EX4200 delivers a future-proofed solution for converging
disparate networks onto a single IP infrastructure.
To ease deployment, the EX4200 supports the industry-
standard Link Layer Discovery Protocol (LLDP) and LLDP-Media
Endpoint Discovery (LLDP-MED), which enable the switches to
automatically discover Ethernet-enabled devices, determine their
power requirements and assign virtual LAN (VLAN) parameters.

In addition, the EX4200 supports rich quality of service (QoS)
functionality for prioritizing data, voice and video traffic. The
switches support eight QoS queues on every port, enabling them to
maintain multi-level, end-to-end traffic prioritizations. The EX4200
also supports a wide range of policy options, including priority and
shaped deficit weighted round-robin (SDWRR) queuing.

Security
The EX4200 line of Ethernet switches fully integrate with
the Juniper Networks Unified Access Control (UAC), which
consolidates all aspects of a user’s identity, device and location,
enabling administrators to enforce access control and security
down to the individual port or user levels.
