HPE 5900AF-48G-4XG-2QSFP network switch

SKU CH-AFES-GKRJJ MPN 5900AF-48G-4XG-2QSFP

A Layer 3 top-of-rack switch with 48 Gigabit Ethernet ports, four 10 Gigabit Ethernet slots and two 40 Gigabit Ethernet slots for high-density data-centre connectivity

  • Switch TypeLayer 3 Switch
  • High-density connectivity with 48 Gigabit Ethernet ports
  • Ultra-low latency top-of-rack design for data centres
  • Layer 3 switching enables advanced routing capabilities
  • Flexible uplinks via four 10 Gigabit and two 40 Gigabit expansion slots
  • Part of HPE FlexFabric architecture for converged traffic

48-port Layer 3 ToR switch

The HPE 5900AF-48G-4XG-2QSFP+ is a top-of-rack Layer 3 switch built for the server access layer of large enterprise data centers. It delivers high-density connectivity and ultra-low-latency switching within the FlexFabric solution. The platform handles converged Ethernet and storage traffic alongside demanding virtualised workloads. It is designed for environments that require performance and density in a single device.

Data-centre access and core deployments

This switch suits network engineers deploying server-access infrastructure in large enterprise data centres or core layers in medium-sized enterprises. It fits teams needing high port density and low latency for virtualised applications and server-to-server traffic. Buyers requiring Power over Ethernet for access points or cameras should look elsewhere. Organisations needing only basic Layer 2 connectivity without routing features will find the Layer 3 capability unnecessary.

48 Gigabit ports with 10G and 40G uplinks

The unit provides 48 Gigabit Ethernet network ports for server connectivity. Four 10 Gigabit Ethernet expansion slots and two 40 Gigabit Ethernet expansion slots serve as high-speed uplinks. This fixed port configuration determines the maximum device density and uplink bandwidth available. Verify that the 10G and 40G uplink mix matches your aggregation design before purchasing.

Questions about this item

How does the 5900AF-48G-4XG-2QSFP+ manage heat and noise when running continuously in a top-of-rack position?

The switch is built for top-of-rack deployment in large enterprise data centres, using a high-density design that handles sustained server-to-server traffic with ultra-low latency.

Which transceivers or cables must I already have to use the 40 Gigabit uplinks on this switch?

The two 40 Gigabit Ethernet expansion slots accept QSFP+ modules, so you need compatible QSFP+ transceivers or direct-attach cables for those links.

Can the 5900AF-48G-4XG-2QSFP+ aggregate traffic from older 1 Gigabit servers through its 48 Gigabit ports?

Yes, the 48 Gigabit Ethernet ports connect legacy 1 Gigabit servers while the four 10 Gigabit and two 40 Gigabit uplinks carry the aggregated traffic upstream.
