Product overview
S4148T is a Dell S4100 S4148T-ON 48-Ports SFP+ 4x QSFP28 2x QSFP+ Switch. A switch is rarely the whole order: optics, breakout cables, the right power orientation and a rail kit all have to arrive with it. Send the topology and we will quote the complete bill of materials.
If the part is wrong for your platform we will say so and suggest the one that is, which is cheaper for both of us than a return.

What you get ordering this from us
Ordered by part number
The order is placed against S4148T, not against a description of it, so there is no room for a substitution you did not agree to.
Quoted with the optics and rails
The switch, the transceivers at both ends and the mounting hardware go on one bill of materials, so nothing blocks the install.
Airflow variant confirmed
We check the airflow direction against your aisle before shipping, because the wrong variant runs hot for the life of the switch.
Questions buyers ask about this part
- Is S4148T genuine and is the warranty intact?
- Yes. It ships new in Dell packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
- Will S4148T work in my server?
- Tell us what it is aggregating and what optics you already hold. We confirm the port mix, the uplink capacity and the airflow variant, and we will list the optics and rail kit you will also need.
- Do you accept purchase orders and quote at volume?
- Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

Specifying a system, not just the part?
Multi-node training is bounded by the fabric between the nodes, so the switch is specified with the cluster rather than after it.
