Juniper Network Equipment Ex3400 1U L2 L3 24 48 Port Poe 10Gbe 40Gbe Junos
Product Description
The Juniper EX3400 is a cost‑effective, fixed‑configuration 1U access switch that brings 40GbE uplinks to enterprise campus networks at an entry‑friendly price point — a rare feature in this class. It supports Virtual Chassis stacking (up to 10 switches, 160 Gbps backplane), field‑replaceable redundant power supplies, and optional front‑to‑back or back‑to‑front cooling for data center GbE access. With Juniper Mist Wired Assurance (ZTP, Marvis AI) and a consistent Junos OS experience, the EX3400 delivers carrier‑class reliability without complexity.
