Set the 3u MDS BIOS to auto power up from power lost

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 switch 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 switch it complicates things a bit.  In such a case when pressing the power on/off switch will power up the side that is off but also initiates Linux Desktop GUI prompted power down sequence which needs to be manually aborted on the on side, if this does not get aborted the on side 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 without having to press the power on/off switch.

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).
