ASUS Pro WS w790 SAGE - 10Gbe LAN port Problems

Hardware Hub Motherboards

Hi All,

First post, long time lurker…

I have a load of w790 boards for work, and they are mostly reasonably stable.

The issue I’m having is the 2 10Gbe ports dont seem to come to life unless they are plugged in before the PSU is plugged in.

If you unplug, power off, plug in, and then power on they seem to be ok.

I dont think this is a windows driver issue, and the 1Gbe Managment port behaves properly. I have updated to the latest BIOS but nothing seems to help.

Once you do this process, you can plug and unplug them, however after some time this process needs to be re done.

When you plug in, you get a random blink fomr the green LED from time to time, no consistent pattern.

Dont get this with any of the X299 Sage Mobos with 10G

Have tried setting the port negotiation on the switch to 1Gb and have tried on multiple switches…

Any ideas?

I don’t have any issues with the 10GBe NICs. Have you tried a different switch and updating the firmware for the NICs?

Me too :slight_smile:

I’ve run into that here on multiple systems, regardless of if they were plugged in first or not.

Same here, but I have some additional info after having this happen on and off for a while now:

  • Happens intermittently after the system is powered down and back up (PSU/BMC remains active).
  • If PSU is cycled, 10G might come back up, or might not. If not, it’s easy to tell since you won’t get a green link light from connected 10G as the BMC boots (they light even before post as the BMC appears to init the 10G interfaces).
  • Seems to be some link to temperatures. More likely in cold environments / cold booting systems that were off for a while. Today I had 3 of 4 systems fail to init 10G on a cold boot, and only after much PSU cycling did I get them all to cooperate.
  • Updating to most recent BMC Firmware V1.1.55 and BIOS 1502 had no apparent impact.
  • Reset CMOS had no impact.
  • All impacted systems were already on the LAN FW update 9.4 mentioned by @iamdjango

Will continue to investigate here, but @tompeel1 please reply here if you found any resolution or elaborating symptoms.

Did anyone every find a solution to this one? We’re seeing it too. Seems linked to colder environments, e.g. <20C.
