The Juniper QFX5120-48Y-AFI2 is a 1U fiber switch with forty-eight SFP28 access connections and eight QSFP28 connections for higher-speed network links. It suits data-center designs that need 10/25GbE server-facing connectivity and 40/100GbE aggregation. The AFI2 configuration uses back-to-front airflow, so the cooling direction is an important part of matching this SKU to the rack.
