Refurbished QFX5120 Switch Hardware Solutions

Juniper QFX is a family of high-performance Ethernet switches designed for enterprise campuses, data centers, cloud environments, and service provider networks. Depending on the model, QFX platforms provide fixed or modular configurations, high port density, and a range of interface speeds. They run Junos OS and are commonly used for leaf-and-spine designs, aggregation, top-of-rack switching, and network expansion.

The Juniper QFX5120-48Y provides 48 ports that support 1GbE, 10GbE, or 25GbE connectivity, plus eight uplink ports supporting 40GbE or 100GbE. This combination allows the switch to connect high-density server or access environments while providing substantial upstream capacity. Verify the exact transceiver, cable, software, and configuration requirements before ordering for compatibility with the intended deployment.

Juniper offers several switch families for different network roles. EX Series switches are widely used for enterprise access and campus environments, while QFX Series switches serve data center, aggregation, and high-performance Ethernet applications. PTX platforms address packet transport needs, and certain legacy or specialized products may remain available through secondary markets. Model selection should consider port speeds, density, power, operating system support, and network architecture.

Yes. Refurbished QFX5120 Switch hardware can be a practical option when you need to replace equipment, add capacity, or standardize an environment at a lower cost than new hardware. Terabit Systems sources refurbished enterprise networking gear and subjects equipment to rigorous testing before certification. Request a quote with the exact model, port requirements, condition preference, and any compatible components needed for your deployment.

Optics are not necessarily included with a switch and should be confirmed as part of the quote. The correct transceiver or cable depends on the selected interface speed, link distance, fiber type, and the equipment at the other end of the connection. Terabit Systems can source compatible optics, cables, and accessories alongside QFX5120 hardware to help simplify the purchasing process.

Terabit Systems backs its refurbished networking hardware with a 1-year replacement or full-refund guarantee if something goes wrong. This protection is supported by rigorous testing procedures intended to verify equipment before resale. For a smooth support experience, retain order details and report any issue promptly. Ask about the specific coverage terms for your quoted switch, optics, modules, and other components before completing an order.

Provide the QFX5120 model or part number, required quantity, preferred condition, needed port speeds, and any optics, cables, or accessories required. Including details about your existing environment helps identify compatible hardware and avoid ordering mismatches. Terabit Systems supports quote-to-order procurement for used and refurbished networking equipment, so buyers can receive pricing tailored to the requested configuration and availability.

Yes. Terabit Systems provides IT asset disposition and buy-back support for used networking equipment, including Juniper switches, routers, optics, and components. This service helps organizations recover fair-market value from surplus or retired gear while reducing the burden of end-of-use hardware management.
