QFX5120-48Y-AFO Overview
QFX5120-48Y-AFO Model and Revision Check
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.
Legacy AFO Versus Current AFO2
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.
Purchase Checks
- Confirm the requested code is QFX5120-48Y-AFO, not AFO2, AFI2 or a DC variant.
- Verify 48 SFP28 access ports and eight QSFP28 uplink ports against the intended optics and breakout design.
- Match front-to-back airflow with the rack hot-aisle and cold-aisle plan.
- Record the installed PSU and fan part numbers, hardware revision, Junos version and support status.
