Optimize your network for virtualization with a high-density, ultra-low-latency ToR switch that features 48 x 10GbE SFP+ and 6 x 40GbE ports (or 72 x 10GbE ports in breakout mode) and up to 720Gbps performance. The S4048-ON also supports Open Network Install Environment (ONIE) for zero-touch installation of alternate network operating systems.


Flexible, powerful 10GbE ToR switches for data centers of all sizes

Deploy modern workloads and applications designed for the open networking era with an optimized data center top-of-rack (ToR) networking solution that:

  • Includes the following switches: S4000-ON Series, S4100-ON Series, S5000 10GbE, S4048T-ON, S4128T-ON, S4148T-ON 1/10G BASE-T, S4148FE, S4248FB-ON, and S4248FLB-ON 10GbE switch.
  • Delivers low latency, superb performance and high density with hardware and software redundancy.
  • Offers Active Fabric designs using S- or Z-Series core switches to create a two-tier, 1/10/40/100GbE data center network architecture.
  • Provides an ideal solution for applications in high-performance data center and computing environments.
Optimized for the open networking era

Get more agility, more choices and lower costs than proprietary networks with select, open-standards-based ON (open networking) switches.

  • Disaggregated-hardware/software solutions bring new levels of freedom and flexibility to your data center.
  • Support for Open Network Install Environment (ONIE) enables zero-touch installation of alternate network operating systems.
  • Your choice of network operating system helps simplify data-center fabric orchestration and automation.
