 Is memory installed correctly?
→ Check if memory is installed correctly.
 Is the memory size large?
→ The memory check may take longer than usual if the installed memory size is large. Wait for a while.
 Did you perform any keyboard or mouse operation immediately after you started the server?
→ If you perform any keyboard or mouse operation immediately after start-up, POST may accidentally
detect a keyboard controller error and stops processing. In such a case, reboot the server. Do not
perform any keyboard or mouse operation until the BIOS start-up message appears after you reboot the
server.
 Are memory and PCI devices supported for use with this server?
→ Operation of the server with unauthorized devices is not guaranteed.
