Unlike the S5248F-ON, a 25GbE top-of-rack switch, and the S5232F-ON, a 32-port 100GbE spine and leaf switch, it adds 400GbE ports. The fabric is rated at 8 Tbps half duplex and 2.6 billion packets each second, with latency under 1135 nanoseconds. Each 100GbE port also runs at 10, 25 or 50GbE, and the 400GbE ports step down to 10GbE. SFP56-DD ports use PAM4 signaling, so QSFP28 optics and breakout cables do not work in them, while two SFP+ ports handle 10GbE. An 8-core Intel Denverton C3758 processor and 32 GB of DDR4 ECC memory sit alongside hardware tables that reach 256K MAC addresses and 875K IPv4 routes. ONIE support lets the switch boot Dell SmartFabric OS10, Enterprise SONiC or a third-party network operating system. Two hot-swappable power supplies provide 1+1 redundancy, and six hot-swappable fan trays provide 11+1 rotor redundancy. Management access uses one 10\/100\/1000BASE-T port plus an RJ45 console port, and a timing card adds PTP and Synchronous Ethernet.\u003c\/p\u003e","brand":"Dell","offers":[{"title":"Default Title","offer_id":68276341735597,"sku":"S5448F-ON-REF","price":7895.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0640\/7667\/7293\/files\/S5448F-ON.webp?v=1794596505","url":"https:\/\/netmode.com\/products\/dell-s5448f-on-powerswitch-100-400gbe-aggregation-switch-refurbished","provider":"Netmode","version":"1.0","type":"link"}
