Juniper QFX5200-48Y-DC-AFI 48x25G + 6x100G Switch

Usage Area

The Juniper QFX5200-48Y-DC-AFI is a 1U top-of-rack switch designed for high-performance data center deployments. It is deployed to provide 25GbE server connectivity and 100GbE uplink aggregation within enterprise and cloud-scale networks. The device supports the construction of scalable EVPN-VXLAN fabrics, enabling efficient multi-tenant network segmentation. Its DC power input and back-to-front airflow (AFI) make it suitable for data center hot-aisle containment environments.
