QFX5120-48Y-AFO belongs to Juniper's QFX5120-48Y fixed data-center switch family. Juniper documents the 48Y platform with 48 SFP28 ports supporting 1/10/25GbE and eight QSFP28 ports supporting 40/100GbE. The AFO suffix denotes the airflow-out direction used for front-to-back cooling.
Juniper's current Hardware Compatibility Tool and ordering information list QFX5120-48Y-AFO2 for the AC, front-to-back variant. The shorter QFX5120-48Y-AFO code appears in older software support references. A quote for the legacy code should therefore identify the chassis revision, installed power supplies, fan modules, Junos release and support eligibility instead of silently substituting AFO2.
