Product overview
The Dell 28x10G-T 2x100G 960Gbps ToR Switch is supplied under part number S4128T-ON. 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.
We return an itemised quote within 48 business hours, and we say plainly when a part is constrained rather than quoting a date we cannot hold.

What you get ordering this from us
Ordered by part number
The order is placed against S4128T-ON, not against a description of it, so there is no room for a substitution you did not agree to.
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 S4128T-ON 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 S4128T-ON work in my server?

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.
