Frequently Asked Questions

What are the primary port specifications for the Juniper QFX5120-48T-AFI? +

The QFX5120-48T-AFI is a high-performance, fixed-configuration switch featuring 48 multi-gigabit 10GbE RJ45 ports for server connectivity and 6 QSFP28 uplink ports. These uplink ports support 100GbE, 40GbE, or breakout configurations, providing the necessary flexibility for high-density data center leaf deployments or modern enterprise campus core and aggregation environments.

Does the QFX5120-48T-AFI support airflow direction options for data center cooling? +

Yes, the 'AFI' suffix in the model number designates an Airflow-In (front-to-back) cooling configuration. This design is specifically engineered for hot-aisle/cold-aisle rack layouts, ensuring that intake air is pulled from the port side and exhausted through the power supply side to maintain optimal thermal stability within high-density server environments.

Can the QFX5120-48T-AFI handle high-bandwidth applications in an enterprise core? +

This platform is built for heavy-duty traffic loads, offering high-throughput switching capacity with low latency. It is specifically designed to handle large-scale virtualization and storage traffic. With its robust architecture, it reliably manages heavy East-West traffic patterns common in modern data centers and high-speed campus networks requiring non-blocking performance across all 10GbE ports.

Which operating system does the Juniper QFX5120-48T-AFI utilize for network management? +

The switch runs on the Junos OS, Juniper's mature and programmable network operating system. This allows for consistent operational procedures across your infrastructure, enabling advanced features like automation via APIs, sophisticated routing protocol support, and granular control over network traffic, which simplifies the overall management of your switching fabric.

Is the QFX5120-48T-AFI suitable for a spine-leaf network architecture? +

Absolutely. The QFX5120-48T-AFI is a versatile solution frequently deployed as a leaf switch in IP-based fabric architectures like EVPN-VXLAN. Its density of 10GBASE-T ports makes it an excellent choice for connecting server farms or access points, while its 100GbE uplink capacity allows for seamless connectivity to a high-speed spine layer.

Does the QFX5120-48T-AFI support redundant power supplies for high availability? +

The chassis is designed with support for redundant, hot-swappable power supplies to ensure continuous uptime. This hardware redundancy is critical for mission-critical deployments where power circuit failure or supply degradation cannot be permitted to disrupt network services. Ensure your deployment includes the appropriate power modules to match your facility's power infrastructure requirements.

How do I automate provisioning and configuration on the QFX5120-48T-AFI? +

Junos OS supports industry-standard automation tools, including ZTP (Zero Touch Provisioning), Python scripts, and REST APIs. These features enable network engineers to streamline device deployment and management, significantly reducing manual configuration errors and accelerating the time-to-service for large-scale network infrastructure refreshes or branch office expansions.

What is the physical footprint of the QFX5120-48T-AFI in a standard rack? +

The QFX5120-48T-AFI is a compact 1U rack-mountable switch. Its form factor is optimized for space efficiency in constrained server cabinets, allowing you to maximize port density per rack unit. Its chassis design integrates seamlessly into standard 19-inch EIA racks, making it an ideal hardware choice for dense data center environments or wiring closets.

Can I obtain a bulk quote for multiple QFX5120-48T-AFI units through BuyRouterSwitch.com? +
