Overview

QFX5120-48Y-AFO2 Overview

QFX5120-48Y-AFO2, Juniper Networks QFX Series QFX5120-48Y - Switch - L3 - managed - 48 x 1/10/25 Gigabit SFP28 + 8 x 40/100 Gigabit QSFP28 - front to back airflow - rack-mountable

The QFX5120 Switch delivers rich, low latency Layer 2/Layer 3 features and advanced EVPN-VXLAN capabilities, making it an ideal data center top-of-rack and distribution switch for campus enterprise deployments.

Featuring L3 gateway capabilities for routing between virtualized and bare-metal servers, the QFX5120 is designed for extremely agile data centers that require support for overlay/underlay network architectures. Native 25GbE with 100GbE uplink ports on the QFX5120-48Y and QFX5120-48YM, 10GbE/1GbE copper with 100GbE uplink ports on the QFX5120-48T, and 32 100GbE ports on the QFX5120-32C make the QFX5120 family ideal for spine-and-leaf network deployments.

The Juniper Networks QFX5120 Switch delivers high scale, high availability, and high performance for data center and campus deployments. The QFX5120 Switch is a versatile routing and switching platform addressing higher server access speed and campus distribution use cases while offering high-density 1GbE/10GbE/25GbE and 100GbE uplinks for collapsed spine data center or campus distribution deployments.

The QFX5120-48Y 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 4 Tbps L2 and L3 performance (bidirectional), with latency as low as 800 nanoseconds
• A 2.2 GHz quad-core Intel CPU with 16 GB memory and 50 GB SSD storage
