I have a storage Chassis SC846BA-R1K28 and Mainboard X9DR7-LN4F did not start up anymore. Then I unplugged and replugged some SAS cables, and tried to locate which Disk slots are served by which cable. After pushing the power button it showed "supermicro"-screen with "System Initializing..." on the bottom and then did not do anything further. IPMI shows the message "System initializing... B7". Removing the Bios battery for some time did not solve the problem. I did not find an answer on the internet yet - could you please tell us what this means and how I can recover from this?
With the message "System Initializing B7 or B9” stop code mean that your memory is got stuck. Please check each memory module individual to see which one cause the problem.
