i have a Supermicro E5520 with MB=X8DTU-F. the server will not boot successfully either thru it's local HDD or a bootable CD/DVD/USB. When selected the CD/DVD to boot I can see a line for Linux (using a ESX 6.0 Live CD) and then the server reboots. When selected to boot off the local HDD it does the same. I also tried booting it off USB that contains bootable Puppy linux image but it also behaves the same way. I disabled the Watchdog (thru BIOS and not jumpers on MB) with no joy. It almost sounds like not enough power to drive the system full on?? no alarms/events with the 2x PSU in use. any help is appreciated. thanks.

This is quite an old motherboard. It may simply have failed. My first step would be to try other memory, and then another power supply. Use one PSU at a time. – wurtel Nov 06 '19 at 07:44

Thanks Wurtel. As you said,i installed every RAM in a sequence until i could recreate the issue.What i noticed is the "BLUE" colored memory slots wouldn't recognise the new RAM i had bought.Rather,i installed the legacy RAM chip in those slots. it seems the PSU's are OK. At least now i can boot from CD/USB. Thanks again for help. – gompie Nov 07 '19 at 22:59
