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) SFP/SFP+ uplink ports and two 40GbE 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.
