EX3400 Ethernet Switches are a cost-effective solution for today's most demanding converged data voice and video enterprise access networks. The compact fixed-configuration 1U devices offer levels of performance and management previously available only with high-end access switches.

Featuring models offering either 24 or 48 10/100/1000BASE-T ports the EX3400 switches also support IEEE 802.3af Power over Ethernet (PoE) or 802.3at PoE+ for powering networked telephones video cameras wireless LAN access points and other IP devices. Four front-panel dual-mode (GbE/10GbE) small form-factor pluggable transceiver (SFP/SFP+) uplink ports and two 40GbE quad SFP+ (QSFP+) ports are also available for connecting the switches to upstream devices.

The EX3400 supports Juniper's unique Virtual Chassis technology for interconnecting up to 10 switches that can be managed as a single device. The EX3400 can also be configured as a satellite device in a Junos Fusion Enterprise deployment which aggregates large numbers of access switches into a logical management platform.
