Dell PowerSwitch S4128T-ON provides 28 10GBASE-T ports and two 100GbE QSFP28 ports. It is the copper-access member of the S4128 pair; S4128F-ON uses SFP+ access ports. Match the server cabling to the T model and specify uplink optics separately.
Dell lists AC configurations with two supplies, four fan modules and either I/O-to-PSU or PSU-to-I/O airflow. Verify the actual unit label and module inventory before matching a hot/cold aisle. The model name alone does not identify the airflow option or prove which accessories the offered unit includes.
The model table lists 960 Gbps switching capacity, 720 Mpps forwarding, 250 W typical consumption and 300 W maximum. These are manufacturer chassis figures, not a workload guarantee. Confirm the installed network OS, licensed features and supported optics for the intended deployment; this page does not promise an OS license or support contract.
