HPE Juniper Networking QFX5120-48T-AFO 48-port network switch

Enterprise 48-port layer-3 switch

The HPE Juniper Networking QFX5120-48T-AFO is a managed network switch with 48 Ethernet ports. It delivers layer-3 switching capabilities for routing between VLANs and subnets. This unit targets network engineers building campus or data-centre fabrics that require wire-speed forwarding and full management control.

Rack-mount chassis for dense deployments

A standard rack-mount form factor lets the switch occupy a single unit of cabinet space without proprietary rails. Front-to-back airflow matches typical hot-aisle or cold-aisle layouts so no extra ducting is required. The 48 copper ports free uplink slots on aggregation layers by terminating access connections directly.

Sustained wire-speed forwarding under load

Layer-3 hardware forwarding maintains full throughput across all 48 ports during prolonged traffic bursts from virtualised hosts or storage clusters. The managed operating system provides telemetry and QoS that keep latency predictable when every port runs continuously at line rate.

Cooling matches sustained operation

Front-to-back airflow keeps internal temperatures stable during continuous 48-port line-rate traffic without throttling. Managed QoS and telemetry maintain predictable latency when every port runs at capacity for extended periods.
