Hi,   I tried to search entirely on M620 VRTX for 1GB NDC but none listed. All of them are 10Gb. But I tried searching on M620 M1000e and found 543-BBCU. I am unsure if it would work, but it's worth a try if you're willing to. There is a write up from InfoWorld about VRTX and M620 with R1-2401. I would assume they are using the SKU part I gave you, as it's the only thing listed for M620 M1000e on 1Gb module.    Let me know if you did try and does it work.
Hello I appreciate this is a question about older equipment but hopefully someone will be able to help.  Does anyone know if any of the quad port 1Gb ethernet modules work in the M620.  I would like to use the R1-2401 switch and make use if all 16 available internal ports.  Currently all of my blades have the broadcom dual 10Gb modules installed. I know I cuuld use PCIe cards, but I am trying to keep the fan speed down and adding cards will not help with that. I know none of the quad port cards are listed as supported, but I wondered if anyone had tried it and found them to work OK?  I know there is quad port 1Gb for both the M520 and the M630, so I just find it odd there is not one for the M620. Cheers
