The Dell PowerSwitch S5248F-ON is a high-performance 1RU open networking switch optimized for data center top-of-rack (ToR) and leaf roles in spine/leaf architectures. It features 48x 25GbE SFP28 ports for high-density server connectivity, 2x 200GbE QSFP28-DD uplinks, and 4x 100GbE QSFP28 ports supporting multi-rate 10/25/40/50/100GbE via breakout cables. Delivering 2.0 Tbps switching capacity (4.0 Tbps full duplex) and 1.5 Bpps throughput (3.0 Bpps full duplex) with 847ns low latency, it ensures non-blocking wire-speed performance. Equipped with redundant hot-swappable 750W AC PSUs, 4 fan modules, 16GB CPU memory, 64GB SSD, and 32MB packet buffer, it supports advanced features like VXLAN, DCB, 1588v2 PTP timing, up to 288K MAC addresses, 128K IPv4 routes. ONIE-enabled for Dell SmartFabric OS10 or third-party NOS, it offers flexible airflow options and fresh air compliance to 45°C, ideal for cloud, HPC, and enterprise networks requiring scalable, low-latency east-west traffic handling.
