module does not start automatically

Hello.

I have five MFS5520VI Compute Module (BMC Firmware ok 1.27.1,  BMC Boot ok 0.28, BIOS ok S5500.86B.01.00.0060.092120111445)

I set the value "Reset" in the "Resume on AC Power Loss" option.

After the loss of power module does not start automatically. I have to push the button on the front panel of the module.

What to do?

Thank U.
