Overview
The EX4300-48P is Juniper's heavier access switch with power on every port — the closet machine for floors dense with phones, cameras and access points, in estates that run Junos from the core outward. Refurbished, it delivers powered access at a per-port cost the new-equipment budget cannot answer. Powered ports at this density usually mean cameras and wireless overhead, and the chassis was built for exactly that load. Junos estates value that the closet speaks the same language as the core. Every switch reaches management on the Shenzhen bench, passes physical review, and is photographed and serial-logged before listing. It ships with 1-yr hardwaresys RTB. Stacking and uplink choices shape these orders — note both, count the closets, and request a quote.
