Set the 3u MDS BIOS to auto power up

Robert Leong -

Power on/off dual function problem

The 3u MDS is a two CPU modules in one chassis design, but it has only one power on/off button (located at front right top) affecting both sides.  

Sometimes it might be required to power up one side (because it was off for whatever reason) and leave the other side alone which is already on, but having only one power on/off button complicates things a bit.  In such a case when pressing the power on/off button will power up the side that is off BUT on the side that is already on will initiates a Linux Desktop GUI prompt for power down countdown sequence, this needs to be manually aborted before the 30 seconds count down expires, if this does not get aborted Linux will initiate a power down sequence.

Solution

If the BIOS is set to auto power up, then simply unplugging the module and reinserting it will accomplish the power cycling / power on without having to press the power on/off button.

Change the BIOS settings

Reboot the system, at the BIOS press ESC to bring up the BIOS setup Utility.

Select Advanced > Boot Features > Restore on AC Power Loss. Press return to bring up the options, select Power On.

Press F10 to Save the configuration and exit (reboot).
