→ At least one DIMM boards are required for operation.

→ The memory check may take a few seconds if the memory size is large. Wait for a while.

restart the server.

cables are connected in the correct order.
8 Is the power-on order correct?
→ When the server has any external devices connected, power on the external devices first, then the
server.
8 Did you install drivers for connected optional devices?
→ Some optional devices require specific device drivers. Refer to the manual that comes with the device
to install its driver.

→ Some devices connected to the serial or parallel port may require I/O port address or operation mode
settings. Refer to the manual that comes with the board for details to make correct settings.
