Juniper EX3400-24T – 24x1G + 4xSFP+ Ethernet Switch

Product Overview

The Juniper EX3400-24T is a fixed-configuration access switch offering 24 x 10/100/1000 BASE-T ports with integrated uplink flexibility via 4 x 1/10 GbE SFP/SFP+ and 2 x 40 GbE QSFP+ ports (optics sold separately). It runs Junos OS, providing robust Layer 2/Layer 3 switching with wire-speed forwarding, rich quality-of-service (QoS) and advanced VLAN/segmentation features. Designed with redundant, field-replaceable power options, the EX3400-24T supports enterprise access and data-centre topologies that require high throughput and scalable fabric options.

Ideal deployment / environment:
The EX3400-24T is well suited to enterprise access and wiring closet deployments requiring high-density, 1 GbE connectivity with flexible uplinks into distribution or core layers. Its combination of gigabit access ports and high-speed SFP+/QSFP+ uplinks supports aggregation of desktops, wireless access points, VoIP devices and servers while maintaining low latency and high throughput. Virtual Chassis technology allows multiple EX3400 units to be managed as a single logical switch, simplifying expansion in campus networks, branch offices and data-centre access tiers.
