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
fixed-configuration EX3400 supports a number of key features, including:
• Junos Fusion Enterprise allows large numbers of EX3400 switches to be configured
as satellite devices that connect to an EX9200 core aggregation switch to create a
single logical device.
• 24-port and 48-port models with and without Power over Ethernet (PoE/PoE+) are
for campus wiring closet deployments.
• Data center-optimized cooling options offer both front-to-back and back-to-front
airflows, making the EX3400 suitable for GbE data center access deployments.
• Two redundant, field-replaceable power supplies each provide up to 920 watts 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.
• Uplink ports can be configured as Virtual Chassis interfaces and connected via
standard 10GbE/40GbE optic interfaces (40GbE uplink ports are preconfigured by
default as Virtual Chassis ports).
• Comprehensive Layer 2 functionality with RIP and static routing is provided.
• A compact, 13.8-inch deep 1 U form factor supports flexible deployment options.
• An easy-to-manage solution includes centralized software upgrades and a single
management interface.
• Support is available for the same consistent modular Juniper Networks Junos
operating system control plane feature implementation used by all other Juniper
fixed-configuration 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 (optional license required).
• Support is available for IPv6 management, including neighbor discovery, stateless
auto configuration, telnet, SSH, DNS, system log, NTP, ping, traceroute, ACL, CoS
static routing, and RIPng.
• IPv6 routing 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.
