S4128F-ON Overview
Separate server connections from uplinks
S4128F-ON uses twenty-eight SFP+ access positions and two QSFP28 uplink positions. Dell identifies their speeds as 10GbE and 100GbE respectively. The optical-port configuration should not be confused with a copper RJ45 access switch.
Match the rack cooling arrangement
Dell documents both normal and reverse airflow configurations for this model: I/O side to power-supply side, or the opposite direction. Select the configuration to match the rack; the base model name alone does not select an airflow direction.
Check the delivered power configuration
The installation guide lists AC and DC configurations with two power supplies and four fan trays. Confirm the offered unit's power type and installed components rather than assuming every S4128F-ON quotation includes the same AC arrangement. Optics, cables, condition and support coverage should be identified separately.
