Juniper QFX5200-48Y-AFO Overview
Juniper QFX5200-48Y-AFO is a genuine data-center switching fabric product from Juniper, a vendor known for scalable, high-performance networking platforms from the campus edge to the core. Belonging to the Juniper family, the QFX5200-48Y-AFO unit is built to the original factory specification, so it integrates with existing Juniper deployments predictably and behaves exactly as the platform documentation describes. In the network, it is built for high-density data-center and cloud environments, where low latency, high availability and consistent forwarding matter most.
From a specification standpoint, it offers 48 ports for client, server or uplink connectivity. These are the original factory figures for this model, giving administrators a clear picture of what the unit can deliver before it enters service. Standard mounting, cabling and management practices apply, so deployment follows the same procedures as other Juniper hardware already running in the environment.
Typical deployments include access-layer deployments for user, phone and AP connectivity, distribution and core aggregation in campus networks, and top-of-rack and end-of-row switching in data centers. Organizations commonly source it for refresh programs, capacity expansion and spares management, keeping a tested unit on hand so outages stay short and replacements are predictable. The factory detail for this unit reads: “QFX5200”. This makes it a practical choice when original-spec hardware is required at a predictable cost.
Every unit at LinkNewNet is inspected and tested before dispatch, and stock is graded, cleaned and verified for correct operation, including port status, console access and firmware state. Our warranty coverage and responsive technical support protect the purchase after it arrives, and our team can confirm revision levels and software compatibility before you order. For volume requirements we also offer configuration checks and staged delivery options.

QFX5200-48Y-AFO - Juniper Series Notes
This listing is part of the Juniper enterprise networking product family, sourced and tested by LinkNewNet for enterprise deployment. Juniper switch runs Junos OS and is typically deployed in campus access, aggregation, or data-center roles. It provides reliable Layer 2/3 switching for user, server and uplink connectivity, and integrates with Juniper Mist or CLI-based management.
Deployment guidance: When planning this QFX5200-48Y-AFO unit into a network, confirm the Junos OS version required, the power and cooling profile, and the upstream/downstream interface types that match your existing infrastructure. For a like-for-like refresh, match the feature set of the units already in service so management and automation behave consistently.
Our Juniper reconditioning process: Every pre-owned Juniper unit at LinkNewNet passes a documented reconditioning flow before dispatch - visual inspection, internal cleaning, firmware verification, port-by-port testing, and configuration reset to factory defaults. This ensures the unit you receive operates reliably and integrates cleanly with your existing Juniper management tools.
