The Refurbished Juniper Networks QFX5110-48S-AFI is a 1U fixed-configuration data center switch built for modern, high-performance network environments. Equipped with 48 x 10GbE SFP+ ports and 4 x 100GbE QSFP28 uplink ports, this switch provides the port density and uplink bandwidth required for demanding enterprise and cloud data center deployments.The AFI suffix designates airflow direction as front-to-back (airflow in), making it well suited for standard hot-aisle/cold-aisle data center rack configurations. Powered by Juniper's Junos operating system, the QFX5110-48S-AFI delivers a consistent, reliable feature set including advanced Layer 2 and Layer 3 protocols, VXLAN support, EVPN, and robust automation and telemetry capabilities.
The QFX5110 series is purpose-built for spine-and-leaf fabric deployments, IP fabric underlay/overlay architectures, and high-density top-of-rack switching. Its combination of 10GbE server-facing ports and 100GbE uplinks ensures ample bandwidth for east-west traffic patterns common in virtualized and containerized workload environments.
Purchasing this unit in Refurbished condition from WhaleyComm provides enterprise-grade performance at a fraction of the cost of new hardware, without sacrificing reliability. Every Refurbished unit is inspected and tested prior to shipment, making the QFX5110-48S-AFI an excellent choice for budget-conscious IT teams that refuse to compromise on network quality.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The 'AFI' suffix indicates the airflow direction of the unit — specifically Airflow In, meaning air flows from the front of the chassis to the rear. This front-to-back airflow pattern is designed for standard hot-aisle/cold-aisle data center rack configurations.
The QFX5110-48S-AFI runs Juniper Networks' Junos OS, providing a consistent and feature-rich network operating system that supports advanced Layer 2/Layer 3 protocols, EVPN, VXLAN, and extensive automation and telemetry capabilities.
Refurbished means this unit is a previously deployed or off-lease switch that has been inspected and tested to verify functionality prior to resale. Purchasing Refurbished hardware allows organizations to obtain enterprise-grade Juniper performance at a significantly reduced cost compared to new equipment.
The 48 SFP+ ports require 10GbE SFP+ transceivers, while the 4 QSFP28 uplink ports support 100GbE QSFP28 transceivers. Juniper-branded optics are recommended for full compatibility and support, though compatible third-party transceivers may also be used depending on your network requirements.
