This is a genuine Dell EMC S5248F-ON 48x 25GbE SFP28, 2x 200GbE QSFP28-DD, 4x 100GbE QSFP28 Ethernet Switch (P/N: S5248F-ON-F, E21W, 1XR4W, 01XR4W). Part of the Dell EMC PowerSwitch S-Series, this high-performance, open networking switch is engineered for demanding data center, enterprise, and cloud environments. It provides exceptional port density and a flexible mix of speeds, including 48x 25 Gigabit Ethernet (25GbE) SFP28 ports for high-speed server and storage connectivity, 2x 200 Gigabit Ethernet (200GbE) QSFP28-DD (Double-Density) ports for ultra-high bandwidth uplinks or inter-switch links, and 4x 100 Gigabit Ethernet (100GbE) QSFP28 ports for additional high-capacity connections. The switch comes equipped with 750W power supply units (PSUs) and features Front-to-Back Airflow, optimizing it for standard cold aisle/hot aisle data center deployments. As an "Open Networking" switch, it supports a variety of Network Operating Systems (NOS), providing unparalleled flexibility and choice for network architects.
