QFX5120-48Y-AFO2 Overview
QFX5120-48Y-AFO2 Exact Configuration
QFX5120-48Y-AFO2 is a fixed 1U QFX5120 switch with 48 SFP28 ports supporting 1/10/25GbE and eight QSFP28 ports supporting 40/100GbE. The AFO2 suffix identifies AC power and airflow out, not a generic QFX5120-48Y chassis.
Airflow-Out Hardware
Juniper's hardware guide lists two 650 W AC power supplies with front-to-back airflow and Gold ejector levers. Five matching fan modules use the AIR OUT label and Gold handles. AFI2, DC-AFO2 and DC-AFI2 are different power or airflow configurations and should not be mixed.
Capacity and Optics Planning
Juniper's Hardware Compatibility Tool lists 4 Tbps bidirectional throughput, 2 Bpps forwarding, a fully loaded weight of 23.7 lb and a 1.72 x 17.36 x 20.48 inch chassis. Transceivers, breakout cables and Junos release support must be checked in the current compatibility tool before ordering.
- Match the complete QFX5120-48Y-AFO2 SKU.
- Verify front-to-back hot-aisle airflow and Gold AIR OUT components.
- Confirm AC input, rack power cords and redundancy.
- Validate SFP28/QSFP28 optics, breakout mode and Junos support.
