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 is connected to a power outlet (or UPS) that meets the power specifications
for the server.

Make sure to use the power cord provided with the server. 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 supplies power. See the
manual that comes with the UPS for details.
Power supply to the server may be linked with the connected UPS using the BIOS SETUP utility of
the server.

Did you press the POWER switch?
→ When power cord is connected, the initialization of management controller starts. During initialization,
the POWER LED is unlit. To power on the server, press the POWER switch after the POWER LED is
lit green.

Did you install the CPU/IO module properly?
→ Check if the CPU/IO module is properly installed in the server. Secure the CPU/IO module with screw
located on the module removable handle.
[?] The screen does not turn on.

Wait until the NEC logo appears.
[?] POST fails to complete:

Are the DIMMs installed?
→ Check if DIMMs are installed correctly.

Is the memory size large?
→ The memory check may take a time if the 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 proceeding. In such a case, restart the server. Do not
perform any keyboard or mouse operation until the BIOS start-up message appears when you restart
the server.

Does the server have appropriate memory boards or PCI card?
→ Operation of the server with unauthorized devices is not guaranteed.

Did you install the CPU/IO module properly?
→ Check if the CPU/IO module is properly installed in the server. Secure the CPU/IO module with screw
located on the module removable handle.
