QFX5120-48Y-AFO2 Overview

QFX5120-48Y-AFO2 is one type of the Juniper QFX5120-48Y Switch, which belongs to the Juniper Networks® QFX5100 Series Switch.

As one of the four compact 1 U platforms of the QFX5120 Switch, the QFX5120-48Y-AFO2 is a 25GbE/100GbE data center leaf and campus distribution switch featuring:

48 25GbE (SFP28)/10GbE (SFP+)/1GbE (SFP) downlink ports
Eight 100GbE (QSFP28)/40GbE (QSFP+) uplink ports
Up to 2/4 Tbps (uni/bidirectional) of L2 and L3 performance, with latency as low as 800 nanoseconds
A 2.2 GHz quad-core Intel CPU with 16 GB memory and 50 GB SSD storage

The QFX5120-48Y-AFO2 support tri-speed 1GbE/10GbE/25GbE, making them a perfect fit for top-of-rack deployments. The 48 ports of native 10GbE/25GbE for server connectivity, plus up to eight 40GbE or 100GbE ports for uplink connectivity, provide very low oversubscription of 1.5:1 from access to aggregation.

The QFX5120-48Y-AFO2 supports Flex Software Subscription Models.
