Black 1U rack-mount switch with front-to-back airflow, 48 SFP+ and 4 QSFP28 ports

HPE

HPE Aruba CX 8100 48XF4C network switch

SKU CH-0VWG-9B9V4

A 1U switch with 48 10GbE SFP+ ports and four 100GbE QSFP28 uplinks, running AOS-CX for automation and analytics

  • 48 ports support 10 GbE and 1 GbE connectivity
  • Four 100 GbE QSFP28 uplinks enable high-speed aggregation
  • 1U form factor fits dense rack deployments
  • 120 W idle and 450 W max power draw
  • AOS-CX automates operations with REST APIs and Python

Compact 1U form factor

The HPE Aruba CX 8100 48XF4C is a manageable Layer 3 network switch built for campus core, aggregation and top-of-rack data centre deployments. It runs the AOS-CX operating system with REST API and Python automation, delivering real-time analytics and zero-service-disruption control-plane resilience. Front-to-back airflow fits standard rack layouts.

Suited for high-density 10G and 100G uplinks

Network teams needing a mix of 1G, 10G, 40G and 100G fibre connectivity in a single rack unit will benefit from the flexible port configuration and line-rate performance. Organisations requiring copper RJ-45 access ports or integrated Power over Ethernet for endpoint devices should evaluate alternative models that provide those interfaces.

48 SFP/SFP+ plus 4 QSFP28 ports

The switch provides 48 ports for 10GBase-X and 4 ports for 100GBase-X with 4x10G and 4x25G breakout capability, enabling dense fibre aggregation. Maximum power draw is 450W while idle consumption sits at 120W, giving facilities teams clear figures for thermal and circuit planning.

Questions about this item

How do I confirm the CX 8100 48XF4C is operating correctly after installation?

Check the front-panel LEDs for power, fan and port status; verify the AOS-CX dashboard shows all 48 SFP/SFP+ and 4 QSFP28 ports linked at line rate; confirm idle draw is near 120 W and max draw does not exceed 450 W.

What ships with the switch and what must I order separately?

The 1U chassis with front-to-back airflow is included; SFP, SFP+, QSFP+ and QSFP28 transceivers and compatible fiber or copper cables for 1/10/40/100 GbE links are not included and must be purchased separately.

Which port-speed combination should I choose for a mixed 10 GbE and 100 GbE deployment?

Use the 48 SFP/SFP+ ports for 1 GbE or 10 GbE connections and the 4 QSFP28 ports for 40 GbE or 100 GbE uplinks; each QSFP28 can also break out to 4×10 GbE or 4×25 GbE when needed.
