Description

The Juniper QFX5120-48Y is a fixed-configuration data centre switch from the QFX5120 family, suited to top-of-rack and leaf switching in 25G server environments.

This AFO2 model provides 48 x 25GbE SFP28 ports for server connectivity, with 8 x 100GbE QSFP28 ports for uplinks. It uses an airflow-out cooling configuration and is powered by redundant AC power supplies and fans, helping maintain availability in dense rack deployments. It ships with base software features.

Choose this variant when your rack layout requires airflow-out cooling together with AC redundant power supplies and fans, and when you need a high-density 25G access layer with 100G uplinks.
