Upon Power On to the End of POST

[?] Fail to power on the server

Is the server properly supplied with power?
→ Check if the power cord connects to the power outlet (or UPS) that meets the power specifications for the
server.
→ Use the power cord that comes with the server. Additionally, check the power cord for broken shield or
bent plugs.
→ Make sure the power breaker for the connected power outlet is on.
→ If the power cord is plugged to a UPS, make sure the UPS is powered and it outputs power. Refer to the
manual that comes with the UPS for details.

Did you press the power switch?
→ When the power cord is connected, the management controller is initialized. The power cannot be turned
on during initialization, even if the POWER switch is pressed. The POWER LED lights amber during
initialization. Press the POWER switch after the POWER LED turns off.
[?] Nothing is displayed on screen
→ It may take time to display NEC logo. Wait for a while.
[?] POST does not complete

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.
