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.
