Unlike the S4148F-ON, which uses 48 SFP+ ports, and the S4128T-ON, which has 28 10GBASE-T ports, this model offers 48 copper ports alongside both QSFP+ and QSFP28 uplinks. Its two QSFP+ ports run at 40GbE, and its four QSFP28 ports run at 100GbE. Breakout cabling can yield 8 interfaces at 50GbE, 16 at 25GbE or as many as 72 at 10GbE. Switching runs non-blocking and cut-through at 880 Gbps, with a throughput of 1320 Mpps and 12 MB of packet buffer. Scaled modes push the MAC table to 272K addresses, the ARP table to 200K entries and the IPv4 route table to 200K routes. ONIE support opens the switch to Dell SmartFabric OS10 and to select third-party network operating systems. Both AC power supplies and all four fan trays, each holding two fans, are redundant and hot-swappable. A built-in 10\/100\/1000BASE-T port handles management, while console connections are offered as RJ-45 and as micro-USB-B.\u003c\/p\u003e","brand":"Dell","offers":[{"title":"Default Title","offer_id":68277092712621,"sku":"S4148T-ON-REF","price":1495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0640\/7667\/7293\/files\/S4148T-ON.webp?v=1794601846","url":"https:\/\/netmode.com\/products\/dell-s4148t-on-powerswitch-1ru-48-port-10gbase-t-switch-refurbished","provider":"Netmode","version":"1.0","type":"link"}
