Description
The Juniper QFX5120‑48Y‑AFO2 is a next‑generation fixed‑configuration Ethernet switch engineered for high‑density campus distribution, data center leaf, and aggregation deployments. Built on Juniper’s Junos OS, this versatile 1 RU switch delivers robust Layer 2 and Layer 3 switching and routing with ultra‑low latency and rich automation capabilities. It features 48 multispeed SFP28 ports capable of operating at 1 GbE, 10 GbE, or 25 GbE speeds using appropriate optics, alongside 8 high‑speed QSFP28 uplink ports that support 40 GbE or 100 GbE connectivity for scalable uplinks or spine‑leaf fabrics.
Designed to support flexible network architectures, the QFX5120‑48Y‑AFO2 runs on a quad‑core CPU with generous memory and SSD storage, enabling advanced services such as EVPN‑VXLAN, BGP, MPLS, and automation via Ansible, Python, and zero‑touch provisioning (ZTP). With up to 4 Tbps bidirectional throughput, this platform handles demanding traffic patterns while maintaining reliability and performance. Redundant AC power supplies and front‑to‑back airflow cooling make it suitable for modern rack‑based deployments.
Key Features:
• 48 multispeed SFP28 ports supporting 1/10/25 GbE with optics (downlinks).
• Eight QSFP28 uplink ports configurable for 40 GbE or 100 GbE connectivity.
• High‑performance switching with up to 4 Tbps bidirectional throughput and low latency.
• Advanced Junos OS features including EVPN‑VXLAN, BGP, MPLS, and automation support.
• Redundant AC power supplies and front‑to‑back airflow for efficient cooling in racks.
