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

What It Is

The Juniper QFX5100-24Q-AA-AFO is a managed top-of-rack and leaf switch designed for data center access and aggregation deployments. Operating under Junos OS, this 1U fixed-configuration platform provides high-density 40GbE connectivity with flexible breakout capabilities. The model is suited for leaf-spine architectures and high-performance storage network fabrics.

Technical Details

• Ports: 24x QSFP+ 40GbE, expandable to 32 ports
• Breakout support: 40G ports can be split into 4x10GbE via breakout cables
• Switching capacity: 2.56 Tbps
• Form factor: 1U rack-mountable
• Power supply: AC (denoted by the -afo suffix)
• Operating system: Junos OS

Configuration & Options

• Base unit includes 24 populated QSFP+ 40GbE ports; expansion to 32 ports requires optional port activation
• Breakout cables (QSFP+ to 4xSFP+ 10GbE) supported for increased 10G port density
• AC power supply configuration as indicated by the -afo model suffix
• Suitable for use as a leaf switch in leaf-spine topologies or as an aggregation switch for server 10G/40G uplinks

Operating Conditions

This switch is intended for deployment in enterprise data center environments where high-throughput access and aggregation are required. It operates effectively in leaf-spine network topologies, server aggregation points, and storage-area network (SAN) fabrics. The unit is designed for standard 19-inch racks in controlled climate conditions typical of modern data centers.
