Product overview
8MD6D is a Dell S4112T-ON 12P 12-Ports RJ-45 3-Ports QSFP28 Switch. Airflow direction has to match the rest of the row, and a front-to-back unit dropped into a back-to-front aisle will run hot from day one. Tell us the rack layout and we will confirm the variant.
Ask for the optics and rail kit on the same quote; a switch that arrives without them still cannot be racked.

What you get ordering this from us
Ordered by part number
Quoted and supplied against 8MD6D specifically, so what arrives is what your build sheet asks for.
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.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Questions buyers ask about this part
- Is 8MD6D genuine and is the warranty intact?
- Yes — new and sealed, with the Dell warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will 8MD6D 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 — POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

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.
