DELL EMC PowerSwitch S4048T-ON

The Dell EMC PowerSwitch S4048T-ON switch is the industry’s latest data center networking solution, empowering organizations to deploy modern workloads and applications designed for the open networking era. Businesses who have made the transition away from monolithic proprietary mainframe systems to industry standard server platforms can now enjoy even greater benefits from Dell Technologies’ open networking platforms. By using industry-leading hardware and a choice of leading network operating systems to simplify data center fabric orchestration and automation, organizations can tailor their network to their unique requirements and accelerate innovation. These new offerings provide the needed flexibility to transform data centers. High-capacity network fabrics are cost-effective and easy to deploy, providing a clear path to the software-defined data center of the future with no vendor lock-in. The S4048T-ON supports the open source Open Network Install Environment (ONIE) for zero-touch installation of alternate network operating systems, including feature rich Dell EMC Networking OS9 and Dell EMC SmartFabric OS10.
High density 1/10G BASE-T switch The Dell EMC PowerSwitch S-Series S4048T-ON is a high-density 100M/1G/10G/40GbE top-of-rack (ToR) switch purpose-built for applications in high-performance data center and computing environments. Leveraging a non-blocking switching architecture, the S4048T-ON delivers line-rate L2 and L3 forwarding capacity within a conservative power budget. The compact S4048T-ON design provides industry-leading density of 48 dual-speed 1/10G BASE-T (RJ45) ports, as well as six 40GbE QSFP+ up-links to conserve
valuable rack space and simplify the migration to 40Gbps in the data center core. Each 40GbE QSFP+ up-link can also support four 10GbE (SFP+) ports with a breakout cable. In addition, the S4048TON incorporates multiple architectural features that optimize data center network flexibility, efficiency and availability, including I/O panel to PSU airflow or PSU to I/O panel airflow for hot/cold aisleenvironments, and redundant, hot-swappable power supplies and fans. S4048T-ON supports feature-rich Dell EMC Networking OS9 and Dell EMC SmartFabric OS10, VLT, network virtualization features such as VRF-lite, VXLAN Gateway and support for Dell Embedded
Open Automation Framework.
• The S4048T-ON is the only switch in the industry that supports traditional network-centric virtualization (VRF) and hypervisor centric virtualization (VXLAN). The switch fully supports L2 VXLAN gateway function and has hardware support for L3 VXLAN routing.
• The S4048T-ON also supports Dell Technologies’ Embedded Open Automation Framework, which provides enhanced network automation and virtualization capabilities for virtual data center environments.
• The Open Automation Framework comprises a suite of interrelated network management tools that can be used
together or independently to provide a network that is flexible, available and manageable while helping to reduce operational expenses.
