The Juniper Networks EX3400 Ethernet Switch with Juniper Networks Junos Fusion
Enterprise and Virtual Chassis technology provides enterprises with the flexibility and ease
of management that previously was only available with higher-end access switches. The
ꢀxed-conꢀguraꢁon EX3400 supports a number of key features, including:
• Junos Fusion Enterprise allows large numbers of EX3400 switches to be conꢀgured as
satellite devices that connect to an EX9200 core aggregaꢁon switch to create a single
logical device.
Product Overview
• 24-port and 48-port models with and without Power over Ethernet (PoE/PoE+) are
for campus wiring closet deployments.
Juniper Networks EX3400
Ethernet Switch delivers a high-
performance, flexible, and cost-
eꢀecꢁve soluꢁon for today’s
most demanding converged
data, voice, and video enterprise
access environments.
• Data center-opꢁmized cooling opꢁons offer both front-to-back and back-to-front
airflows, making the EX3400 suitable for GbE data center access deployments.
• Two redundant, ꢀeld-replaceable power supplies each provide up to 920 waꢂs of
power.
• 24-port data center models are included for metro deployments.
• Four dual-mode (GbE/10GbE) small form-factor pluggable transceiver (SFP/SFP+)
uplink ports and two 40GbE QSFP+ ports are available.
To simplify network operaꢁons,
the EX3400 is hardware-ready

to act as a satellite device to
support a Juniper Networks
Junos Fusion Enterprise
deployment, which can combine
several wiring closets into one
logical management plaꢂorm.
The EX3400 also supports
Juniper Networks Virtual
• Uplink ports can be conꢀgured as Virtual Chassis interfaces and connected via
standard 10GbE/40GbE opꢁc interfaces (40GbE uplink ports are preconꢀgured by
default as Virtual Chassis ports).
• Comprehensive Layer 2 funcꢁonality with RIP and staꢁc rouꢁng is provided.
• A compact, 13.8-inch deep 1 U form factor supports flexible deployment opꢁons.
• An easy-to-manage soluꢁon includes centralized soꢃware upgrades and a single
management interface.
• Support is available for the same consistent modular Juniper Networks Junos
operaꢁng system control plane feature implementaꢁon used by all other Juniper ꢀxed-
conꢀguraꢁon Juniper Networks EX Series Ethernet Switches.
• Support Is provided for Layer 3 (OSPF v2, IGMP v1/v2/v3, PIM, VRRP, Q-in-Q, BFD,
virtual router) via an enhanced feature license (opꢁonal license required).
• Support is available for IPv6 management, including neighbor discovery, stateless auto
conꢀguraꢁon, telnet, SSH, DNS, system log, NTP, ping, traceroute, ACL, CoS staꢁc
rouꢁng, and RIPng.
Chassis technology, allowing up
to 10 switches to be
interconnected over uplink ports
and managed as a single device,
delivering a scalable, pay-as-
you-grow soluꢁon for expanding
network environments.
• IPv6 rouꢁng features (OSPFv3, virtual router support for unicast, VRRPv6, PIM,
MLDv1/v2) are supported via an enhanced feature license.
• Energy Efficient Ethernet (EEE) capability is provided.
