Overview
The EX3400-48T is Juniper's full-size access switch for the wiring closet proper — Junos at the edge of the campus, in the denser chassis that anchors a floor rather than a corner of it. Refurbished EX-series stock keeps Junos estates consistent without paying new-switch prices for a solved problem. Virtual-chassis behaviour means closets scale by stacking rather than redesigning. One operating system from core to closet is the quiet luxury of a Juniper shop. Each switch reaches its management prompt on our Shenzhen bench, passes physical review, and leaves a photo and serial trail before listing. It ships with 1-yr hardwaresys RTB. Access layers deploy in multiples — send the closet count and the uplink medium, then request a quote.
