Product overview
4KTG1 is a Dell S4128T-ON 28-Ports RJ-45 2x 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
4KTG1 is what is quoted and 4KTG1 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
Is 4KTG1 genuine and is the warranty intact?
Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
Will 4KTG1 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. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

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.
