Each EX4300 switch includes an integrated application-specific
integrated circuit (ASIC)-based Packet Forwarding Engine, the EX-
PFE, while an integrated Routing Engine (RE) delivers all control
plane functionality. The EX4300 also leverages the same modular
Junos OS as other Juniper Networks switches, routers, and security
devices, ensuring a consistent implementation and operation of
control plane features across the Juniper Networks infrastructure.

Architecture and Key Components
The EX4300 switches are single rack unit devices that deliver
a compact solution for crowded wiring closets and access
switch locations where space and power are at a premium. Each
EX4300 supports four standard 40GbE QSFP+ ports which can
support high-speed Virtual Chassis backplane connections or
serve as uplinks to upstream aggregation devices (note that the
40GbE ports cannot be split into 4x10GbE ports). In addition,
each EX4300 supports an optional front panel uplink module
offering four 1GbE or 10GbE ports for high-speed backbone or link
aggregation connections between wiring closets and upstream
aggregation switches, providing up to 40GbE of aggregate
bandwidth. Uplink modules can be installed without powering
down the switch, enabling users to add high-speed connectivity
at any time or migrate from one uplink type to the other, delivering
the ultimate in flexible, high-performance interconnectivity.

The EX4300 also features a front panel LCD that offers a flexible
interface for performing device bring-up and configuration
rollbacks, reporting switch alarm and LED status, or restoring the
switch to its default settings. when deployed as a member of a
Virtual Chassis configuration, the LCD also displays the switch’s
chassis “slot number” and RE status for rapid identification and
problem resolution.

A dedicated rear panel RJ-45 port is available for out-of-band
management, while a rear panel USB port can be used to easily
upload Junos OS and configuration files. In addition, a dedicated
front panel USB console port and a rear panel RJ-45 console port
offer flexible out-of-band console options.

Virtual Chassis Technology
Up to 10 EX4300 switches can be interconnected using Virtual
Chassis technology, creating a single logical device supporting up
to 480 10/100/1000BASE-T ports, plus an additional 40 10GbE
or 40GbE uplink ports. EX4300 Virtual Chassis configurations
can be created to support a variety of port and density options for
data center, campus, and branch deployments. Virtual Chassis
connections can be formed using any of the 40GbE ports or 10GbE
ports using standard DAC cables and optics. The EX4300 does not
support Virtual Chassis technology on the GbE copper or fiber ports.

Virtual Chassis Deployments in Campus Wiring Closets
In campus wiring closets, flexible topologies can be created using
standard QSFP+ optics on the 40GbE ports to extend the Virtual
Chassis configuration across long distances spanning multiple
wiring closets, floors, or even buildings while using 10GbE or
40GbE for uplink connectivity.

Virtual Chassis Deployments in the Data Center
when deployed in a Virtual Chassis configuration in the data
center, all EX4300 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. Highly resilient topologies can also be created
using the 40GbE DAC cables.
