Juniper Networks Announces General Availability of EX 3200 and 4200 Series High-Performance Ethernet Switches

SUNNYVALE, Calif.--(Business Wire)--
Juniper Networks, Inc. (NASDAQ:JNPR), the leader in
high-performance networking, today announced the immediate
availability of the EX-series Ethernet switches. Launched recently at
the company's Global Enterprise Event in New York City, Juniper's EX
3200 and EX 4200 switches are available today, and the EX 8200 series
remains on schedule for availability in the second half of 2008.

"Juniper is now shipping the first members of a new family of
high-performance Ethernet switches running on JUNOS software, our
customer-proven single-source network operating system," said Hitesh
Sheth, executive vice president and general manager of the Ethernet
Platforms Business Group at Juniper Networks. "The EX 3200 and 4200
switches deliver operational simplicity and reliability to accelerate
the deployment of applications and services across the extended
enterprise to advance the economics of networking."

"Juniper has proven to be a strategic partner that is more
interested in solving our problems and creating a solution than simply
selling us a box," said Frank Ziegler, vice president of
communications at the Philadelphia Stock Exchange. "The Juniper
Networks EX-series is the fastest switch we've ever tested in our lab,
and the solution gives us the opportunity to deliver consistency
throughout our infrastructure, from the access layer, through the data
center and out to the enterprise edge. Juniper's EX-series switches
will also enable us to deliver an extensive layer of access control to
perform defense-in-depth."

Juniper's EX 3200 series: Fixed-Configuration Platforms

The EX 3200 series switches are fixed-configuration Ethernet
platforms offering a simple, cost-effective, standalone solution for
low-density regional and corporate office deployments. Installed in
wiring closets to provide network access, the 24- and 48-port EX 3200
switches offer simple plug-and-play 10/100/1000BASE-T connectivity to
meet today's converged network requirements. Full and partial Power
over Ethernet (PoE) options are available for supporting IP-enabled
devices such as telephones, security cameras and wireless LAN (WLAN)
access points in converged network environments. Optional four-port
GbE and two-port 10GbE uplink modules with pluggable optics are also
available for supporting high-speed connections to other switches or
upstream devices such as routers. A field-replaceable power supply and
fan tray lowers mean time to repair.

Juniper's EX 4200 series: Virtual Chassis(TM) Technology

The EX 4200 series Ethernet switches with Virtual Chassis
technology combine the reliability, scalability, and ease of
management of modular systems with the economics and flexibility of
stackable platforms, delivering a high-performance, scalable solution
for data center, corporate and regional office environments. Like the
EX 3200 switches, EX 4200 series switches offer 24- and 48-port
10/100/1000BASE-T configurations with full and partial PoE and
optional GbE and 10GbE uplink modules, plus a 24-port fiber switch
offering 100/1000BASE-X support. Using Virtual Chassis technology, up
to 10 EX 4200 series switches can be interconnected over a 128
Gigabit-per-second (Gbps) backplane, creating a single virtual switch
supporting up to 480 10/100/1000BASE-T ports and up to 40 GbE or 20
10GbE uplink ports. All EX 4200 series switches include HA features
such as redundant, hot-swappable internal power supplies and
field-replaceable, multi-blower fan trays to help deliver maximum
uptime.
