Data-center Layer 3 switching

The HPE Juniper Networking QFX5100-48S-AFIProduct is a 48-port 10/40GbE Layer 3 network switch built for dynamic data-center environments. It supports cloud and software-defined networking adoption with rapid application deployment. The QFX5100 series acts as a universal building block for modern switching architectures.

Suited for fabric and spine-leaf deployments

This switch fits teams running mission-critical applications, network virtualisation, or scale-out storage that demand flexible Layer 3 fabrics. It is not for buyers who require modular chassis expansion or different port density than the fixed configuration provides.

48 x 10GbE and 6 x 40GbE fixed ports

The unit delivers forty-eight 10 Gigabit Ethernet expansion slots and six 40 Gigabit Ethernet expansion slots in a non-modular design. This port count and speed mix determines whether the switch matches your topology requirements.

Questions about this item

How does the 48-port 10GbE and 6-port 40GbE configuration perform in a live data center fabric?

The QFX5100-48S-AFI delivers wire-speed Layer 3 switching across all 48 10GbE and six 40GbE ports, supporting spine-and-leaf and fabric deployments for cloud and SDN environments.

What do the 10GbE and 40GbE expansion slots actually accept, and what throughput does each standard cap at?

The 48 SFP+ slots take 10GbE transceivers up to 10 Gb/s each, and the six QSFP+ slots take 40GbE transceivers up to 40 Gb/s each; no higher-speed modules are supported.

What physical space and airflow direction does the QFX5100-48S-AFI require for installation?

The unit is a 1U fixed-configuration switch with front-to-rear (AFI) cooling, designed to mount in a standard four-post rack.
