Juniper QFX5100-24Q-AFO 40GbE Data Center Switch

Equipment Overview

The Juniper QFX5100-24Q-AFO is a managed switch from the QFX5100 series, engineered for access and aggregation roles in enterprise data centers. Designed to handle high-density 40GbE environments, this 1U device provides 2.56 Tbps of switching capacity while operating under Junos OS. It serves as a spine switch in smaller data centers or as an aggregation point for leaf switches with 40GbE uplinks, delivering a high-performance core for dense connectivity scenarios.

Main Parameters

• Ports: 24x QSFP+ 40GbE (expandable to 32 with optional license)
• Switching capacity: 2.56 Tbps
• Breakout support: 40G to 4x10GbE
• Form factor: 1U rack-mountable
• Power supply: AC, airflow AFO (back-to-front cooling)
• Operating system: Junos OS

Key Advantages

The QFX5100-24Q-AFO is selected for enterprise projects requiring robust 40GbE aggregation with low latency and high reliability.
