JUNIPER QFX5200-32C-AFO QFX5200, 32 QSFP+ Ports, Redundant Fans, 2 AC Power Supplies, Front to Back Airflow
Juniper QFX5200-32C-AFO Ethernet Switch
Next-Generation 100GbE Data Center Spine/Leaf Switch
The Juniper QFX5200-32C-AFO is a high-performance 100 Gigabit Ethernet data center switch designed for scalable leaf-spine IP fabric architectures. Developed by Juniper Networks, this compact 1RU platform delivers exceptional throughput, ultra-low latency, and flexible port configurations for enterprise, cloud, and service provider data centers.
Equipped with 32 high-density QSFP28 ports, the QFX5200-32C-AFO supports 100GbE connectivity and is fully backward compatible with 40GbE QSFP+ optics. Each port can also be configured using breakout cables to provide 4×25GbE, 4×10GbE, or 2×50GbE connections, enabling up to 128 server-facing ports for high-density data center deployments.
The switch delivers an impressive 6.4 Tbps switching capacity and 2.4 billion packets per second forwarding rate, ensuring wire-speed performance even in large-scale IP fabric environments. Its programmable switching ASIC enables advanced traffic processing and allows new features and protocols to be introduced through software updates, helping protect long-term infrastructure investments.
Running Junos OS or Junos OS Evolved, the QFX5200-32C-AFO provides a robust and highly automated networking platform with support for EVPN-VXLAN overlays, MPLS, and Layer 3 IP fabrics. These capabilities make it an ideal solution for organizations deploying modern network virtualization and multi-tenant cloud architectures.
The AFO (Airflow Out) design provides front-to-back cooling, where air enters through the port side and exits through the power supply side. Combined with redundant power supplies and hot-swappable fan modules, this design ensures reliable operation in high-density data center racks.
With its high-bandwidth architecture, flexible port breakout capabilities, and advanced network virtualization support, the Juniper QFX5200-32C-AFO delivers a powerful switching platform for cloud infrastructure, enterprise data centers, high-performance computing (HPC), and high-frequency trading environments.

FAQs:
Q1. Does this switch support 25GbE?
Yes. By using a QSFP28-to-SFP28 breakout cable, each 100G port can be split into four 25G ports, allowing for a maximum of 128 x 25GbE ports.
Q2. What is the difference between AFO and AFI models?
AFO (Airflow Out) is port-to-FRU (front-to-back), where air enters the ports and exits the power supplies. AFI (Airflow In) is FRU-to-port (back-to-front), where air enters the power supplies and exits the ports.
Q3. Is the Junos OS license included?
The hardware comes with the base Junos OS. However, advanced features such as BGP, MPLS, or EVPN-VXLAN may require an "Enhanced" or "Premium" software license.
Q4. Can this switch be used as a Spine?
Yes. Due to its high 100GbE port density and 6.4 Tbps capacity, the QFX5200-32C is commonly used as a Spine switch in a 10G/25G leaf-and-spine fabric.
Q5. Does it support SONiC?
Yes. The QFX5200-32C is one of the platforms that supports the SONiC (Software for Open Networking in the Cloud) open-source operating system for users preferring a disaggregated network stack.
