Juniper QFX5110-48S-D-AFO2 48 SFP+ 4 QSFP28 Switch | 1U Enterprise

Keep east-west traffic moving in compact racks with the Juniper QFX5110-48S-D-AFO2. Built for high-density switching, it combines 48 SFP+ ports with 4 QSFP28 uplinks to support aggregation, leaf-spine, and routed access designs without consuming extra rack space. The 1U rack-mountable form factor fits standard enterprise and colocation deployments where port density and predictable airflow matter. Layer 3 support gives network teams the routing control needed at the edge of the fabric, while front-to-back DC airflow aligns with hot/cold aisle planning in modern data centers. The switch’s 10 Gigabit Ethernet foundation makes it a strong fit for server aggregation, storage traffic, and uplink consolidation where oversubscription must stay under control. With Juniper’s QFX family positioning, this model is aimed at environments that need more than basic access switching: it is designed for dense, structured networks where port count, uplink flexibility, and thermal design directly affect operational stability. For teams standardizing on Juniper switching, the QFX5110-48S-D-AFO2 offers a clear balance of density, routing capability, and rack efficiency for demanding infrastructure builds.
