Juniper EX4400-48F-AFI 12x10G 36x1G 2x100G Switch | Enterprise, Rack Mount

Keep access traffic moving as user counts, east-west flows, and uplink demand rise. Juniper EX4400-48F-AFI is built for dense enterprise switching where port mix and uplink capacity matter as much as raw port count. With 12 x 10G ports, 36 x 1G ports, and 2 x 100G uplinks, it supports mixed-speed edge deployments that need room to grow without forcing an early refresh. This model is a strong fit for teams standardizing on high-performance access switching for campus, aggregation, and distribution layers. The 100G uplinks provide the backhaul capacity needed to avoid bottlenecks when multiple access blocks converge, while the 10G and 1G access ports support a broad mix of endpoints, servers, and infrastructure devices. Rack-mountable hardware makes it straightforward to deploy in structured network closets and equipment rooms. For organizations that value predictable scaling, this switch offers the kind of port density and uplink balance that helps preserve network design flexibility. It is well suited to environments where downtime, oversubscription, and port exhaustion carry real operational cost.
