Product Overview

The Juniper EX3400-48T is a high-performance fixed access switch delivering 48 x 10/100/1000 BASE-T ports with robust uplink options and enterprise-class switching capabilities. It runs Junos OS, offering consistent Layer 2/Layer 3 forwarding with enhanced quality of service, security and automation features. With a resilient hardware design and support for Virtual Chassis scaling, the EX3400-48T combines abundant port density with flexible uplinks for aggregation into distribution or core layers in campus and branch networks.

Ideal deployment / environment:
The EX3400-48T is well suited to enterprise access and aggregation deployments that require high-density 1 GbE connectivity with flexible uplink capacity. Its extensive copper port count supports desktops, wireless access points, VoIP devices and IP cameras on a single platform, while 10 GbE and 40 GbE uplinks ensure efficient hand-off to distribution and core layers.
