S4112F-ON is Dell’s half-rack-width 1U switch with twelve SFP+ access interfaces and three 100GbE QSFP28 uplinks. Identify the intended access optics or DACs individually; the bare model designation does not mean transceivers are included. S4112T-ON is the copper BASE-T alternative, so the two access-media inventories must not be confused.
Dell rates this model at 90 W typical and 180 W maximum consumption. The published switching and packet-forwarding figures are 840 Gbps and 630 Mpps. These numbers describe the manufacturer’s platform rating; the selected software, traffic pattern and port configuration still need deployment validation.
The catalog includes AC and DC versions, each offered with I/O-to-PSU or reverse airflow. S4112’s redundant power supplies and fans are fixed. Check the complete unit and airflow labels before replacement, rather than assuming that removable S4100 PSU or fan accessories apply. Confirm the OS license, support term and required optics as separate quotation details.
