Supermicro X11SCH-F - Remote control not working via BMC

[Mike731]

Motherboard Supermicro X11SCH-F.

BIOS and BMC Firmware latest:
Firmware Revision: 01.73.12
Firmware Build Time: 05/10/2021
BIOS Version: 1.6
BIOS Build Time: 05/25/2021

There is a problem with this motherboard.
Remote control via BMC stops working if you do BIOS settings.
After saving the BIOS settings, the BMC no longer sees the power status of the motherboard and cannot connect via Remote control.
BMC does not see the state of the motherboard - it always writes that it is turned off.
Various manipulations with "IKVM Reset" and "Unit Reset" do not help.
Only "Remove current settings and restore to factory default" helps. And then around again.

Can you please tell me if there is any way to solve the problem?

That sounds like physical damage to the board to me. Have you inspected the board for such?
Or a very weird software incompatibilty.

You can technically crossflash BMC FWs with varying degrees of success.
Are you absolutely sure that you flashed the one meant for that board?

I would try reflashing ipmi and bios without keeping any settings and then check if it resolved the problem. If not -> bad news (probably damaged mainboard)

Visually, there is no damage to the board.
In general, the board works fine.
I tested it for several days with Memtest - no problems were found.
I also tested it for several days with Supermicro Super Diagnostics Offline - no problems were found.

I didn't flash the motherboard. It already came out of the box with the latest versions of bios and bmc.

i can only recommend that you post pictures of the front and backsie so that we can look for damage as well.

X11 Boards have no limits on what you are flashing so you can simply select the current FW binary and flash that again just to be absolutely sure.
It has to be something and if it isn't software, you have a hardware issue.
Please post pictures.
The more the better.
