What you get ordering this from us
Ordered by part number
NW42M is what is quoted and NW42M is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
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 NW42M 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 NW42M 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.
