Dell 0NG39H — Mellanox M4001F FDR InfiniBand Blade Switch I/O Module for PowerEdge M1000e
Identity
This listing is for a Dell OEM service part carrying the printed part number 0NG39H. Note on the leading character: Dell service part numbers begin with the digit zero, and labels are routinely misread as the letter O. A unit labelled "ONG39H" is the same part as 0NG39H; the short form NG39H refers to it as well. Multiple independent resellers identify 0NG39H / NG39H as the Dell-branded Mellanox M4001F InfiniBand blade switch I/O module for the PowerEdge M1000e blade enclosure, and the port and speed figures below are taken from Dell's own PowerEdge M1000e Enclosure Owner's Manual and the Dell/Mellanox M4001 product brief. T.E.S confirms the exact model from the unit label before dispatch.
What is confirmed about 0NG39H
The printed part number is 0NG39H (leading character is the digit zero, not the letter O). NG39H is the same part.
Identified consistently across the reseller market as the Dell Mellanox M4001F InfiniBand blade switch I/O module for the PowerEdge M1000e enclosure.
Per Dell's PowerEdge M1000e Enclosure Owner's Manual, the Mellanox M4001F/M4001Q/M4001T InfiniBand switch I/O module carries 16 QSFP ports on the front panel and 16 internal InfiniBand ports.
Per the Dell/Mellanox M4001 product brief, the M4001F delivers 56 Gb/s per port at FDR, and 40 Gb/s at QDR and FDR10.
Hot-swappable. Per the Dell owner's manual the module installs in the M1000e Fabric B or Fabric C slots.
This is a blade-enclosure I/O module. It is not a standalone rack switch and not a PCIe adapter.
What is not yet confirmed
This list is deliberate. It is what T.E.S could not establish from documentation, and it is read off the physical unit before dispatch rather than guessed at here.
Which member of the M4001 family this physical unit is. The M4001F (FDR, 56 Gb/s), M4001Q (QDR) and M4001T (FDR10) share the same module form factor. The 0NG39H number maps to M4001F in reseller data, but the module's own silkscreen is the authority and is what T.E.S reads.
Firmware level, and whether any embedded subnet manager entitlement was ever licensed on this unit.
Whether the unit was pulled from Fabric B or Fabric C, and the running hours behind it.
Cosmetic and mechanical condition of the 16 QSFP cages until the unit is inspected for your order.
QSFP transceivers and cables are not included and are not implied by this listing.
Request label photos before you order
Ask us for photographs of this unit's product label and we will send them before you commit to anything. There are 5 units of 0NG39H in this lot. Because the M4001F / M4001Q / M4001T distinction decides the fabric speed you get, we will photograph the module silkscreen and the full label of the specific units allocated to your order. If the label does not match what is described on this page, we say so and re-quote or cancel — we do not ship a substitute and hope it fits. Quote part number 0NG39H when you contact us.
Frequently asked questions
What exactly am I buying with 0NG39H?
A refurbished Dell OEM service part whose printed number is 0NG39H. It is identified across the reseller market as the Dell Mellanox M4001F FDR InfiniBand blade switch I/O module for the PowerEdge M1000e. Dell's own M1000e Owner's Manual documents this module as having 16 front-panel QSFP ports and 16 internal InfiniBand ports, and the Dell/Mellanox M4001 product brief gives 56 Gb/s per port at FDR. T.E.S confirms the specific M4001 variant from the unit before dispatch.
My label reads ONG39H with a letter O. Is that the same part?
Yes. Dell service part numbers begin with the digit zero, and the zero on a Dell label is frequently read as a capital O. ONG39H, 0NG39H and NG39H all refer to the same Dell part. This is a labelling convention, not a different product.
Will T.E.S confirm the exact model before shipping 0NG39H?
Yes, as a standard dispatch step. We read the printed 0NG39H number and, critically, the M4001 variant silkscreened on the module — F, Q or T — because that determines whether you get FDR 56 Gb/s, QDR or FDR10. If it is not the M4001F described here, we contact you before shipping.
What if 0NG39H turns out not to be what I need?
Tell us the M1000e fabric slot you are filling and the InfiniBand generation you are running before you order, and we check the unit against that first. If the module is a different M4001 variant we re-quote or cancel. If a unit ships and we misread the label, it comes back at our cost.
Is the 0NG39H module tested?
It is cleaned, visually inspected and bench-tested where a suitable test topology is available. For an M1000e I/O module that requires a matching blade enclosure on the bench, which is not always available. Ask what was actually done to the unit allocated to you and we will tell you rather than implying more.
Are transceivers or cables included with 0NG39H?
No. The listing is for the M1000e I/O module only. QSFP transceivers and QSFP DAC or optical cables are separate items and are not included or implied. T.E.S carries QSFP interconnect separately — ask and we will quote the cabling alongside the module.
Why T.E.S IT-SOLUTIONS
T.E.S IT-SOLUTIONS supplies refurbished enterprise networking and server hardware from EU stock to a B2B market. On OEM service parts whose exact model is not established by the part number alone, we publish what we can verify and name what we cannot, instead of filling the gap with plausible-sounding specifications. Every unit is photographed and its label read before dispatch. If the unit differs from this page, we tell you before we ship.
