    Power and Airflow

    Dual 650W AC, front-to-back airflow

    Best Fit Applications

    Data Center Spine-and-Leaf

    Data Center Spine-and-Leaf

    Juniper positions the QFX5120-32C as a fixed 1U spine, leaf, and access switch. Its 32 100GbE/40GbE QSFP28 ports provide dense high-speed interconnects for spine-and-leaf fabrics.

    High-Density 100GbE Aggregation

    High-Density 100GbE Aggregation

    The 32 QSFP28 ports support 100GbE or 40GbE operation for high-bandwidth connections between servers, leaf switches, and data center uplinks.

    Channelized Server Connectivity

    Channelized Server Connectivity

    QSFP28 ports 0–30 can be channelized into 4 x 25GbE or 4 x 10GbE interfaces through supported breakout configurations. Port 31 does not support these 4-way modes.

    Front-to-Back Data Center Deployment

    Front-to-Back Data Center Deployment

    The AFO configuration uses front-to-back airflow, dual AC power supplies, and six fan modules with 5+1 redundancy for compatible data center cooling layouts.

    Why QFX5120-32C-AFO

    High-Density Port Design

    High-Density Port Design

    32 100GbE/40GbE QSFP28 ports deliver high-speed connectivity in a fixed 1U form factor, with 2 native 10GbE SFP+ ports for additional network connections.

    Flexible Breakout Connectivity

    Flexible Breakout Connectivity

    Supported QSFP28 port channelization enables 25GbE and 10GbE connections for server and access-layer designs. Port 31 remains dedicated to non-channelized operation.

    Data Center Performance

    Data Center Performance

    The switch provides 6.4 Tbps bidirectional throughput, 2 Bpps forwarding capacity, and 800 ns latency for demanding Layer 2 and Layer 3 workloads.

    Redundant Hardware Design

    Redundant Hardware Design

    Dual 650W AC power supplies and six hot-removable fan modules provide 1+1 PSU redundancy and 5+1 fan redundancy.

    Automation and Overlay Support

    Automation and Overlay Support

    Junos OS supports automation capabilities, zero-touch provisioning, EVPN-VXLAN, VXLAN OVSDB, and other data center networking functions.
