Juniper QFX5200-48Y Ethernet Switch
High-Density 25GbE/100GbE Data Center Leaf-and-Spine Switch
The Juniper Networks QFX5200-48Y Data Center Switch is a next-generation, high-performance switching platform designed for modern data center fabrics, cloud environments, and enterprise networks. With a compact 1RU form factor, it delivers exceptional port density, scalability, and throughput, making it ideal for organizations transitioning from 10GbE to 25GbE server connectivity.
Equipped with 48 dual-speed 10GbE/25GbE SFP/SFP28 ports and 6 high-speed 40GbE/100GbE QSFP28 uplink ports, the QFX5200-48Y provides a powerful combination of high-density access and ultra-fast uplinks. The QSFP28 ports support breakout configurations (4×10GbE or 4×25GbE), enabling flexible deployment options and increased port density for growing network demands.
Powered by a high-performance programmable ASIC, the switch delivers up to 3.6 Tbps switching capacity and 2.1 Bpps forwarding rate, ensuring wire-speed performance for data-intensive workloads. Its ultra-low latency architecture makes it ideal for virtualization, high-performance computing (HPC), and real-time analytics applications.
The QFX5200-48Y is built for modern, software-defined networking environments, with full support for EVPN-VXLAN, MPLS, and advanced Layer 2/Layer 3 protocols such as BGP, OSPF, and IS-IS. It also supports Junos OS Evolved, offering a modular, resilient, and programmable operating system architecture for enhanced automation and operational efficiency.
Designed for high availability, the switch includes dual hot-swappable power supplies, N+1 redundant fans, and flexible airflow options (AFO/AFI), ensuring reliable operation in diverse data center environments. It also supports advanced automation tools such as Python, Ansible, Puppet, and Chef, enabling streamlined provisioning and network orchestration.
With its combination of 25GbE efficiency, 100GbE scalability, programmable architecture, and compact design, the Juniper QFX5200-48Y is a future-ready solution for organizations building high-performance, scalable, and automated data center networks.

FAQs:
Q1. Are the 25GbE ports backward compatible with 10GbE?
Yes. The 48 SFP28 ports are dual-speed and can support either 10GbE SFP+ or 25GbE SFP28 transceivers and DAC cables.
Q2. Does this switch support Virtual Chassis?
The QFX5200-48Y primarily focuses on IP Fabric architectures (like EVPN-VXLAN). While it supports high-availability features, it is typically deployed as a standalone leaf or spine in a fabric rather than a traditional Virtual Chassis.
Q3. Can I use the 100GbE ports for 40GbE?
Yes. The QSFP28 ports are backward compatible with 40GbE QSFP+ optics.
Q4. What is the benefit of 25GbE over 10GbE?
25GbE provides significantly higher throughput for modern flash storage and virtualized workloads while utilizing a single-lane signaling technology similar to 10GbE, keeping power and cabling costs low.
Q5. Is this switch available with different airflow directions?
Yes. Like most QFX switches, it is available in Port-to-FRU (AFO) or FRU-to-Port (AFI) configurations to match your data center's hot/cold aisle requirements.
