POST flow details

This topic walks you through how POST is performed.

When you power on the system, one selected CPU/IO module will start up. POST will be performed on this selected CPU/IO module.
The memory check starts. A message appears at the upper left of the screen to show that the basic and expanded memories are being counted. The memory check may take a few minutes to complete depending on the server's memory size. Likewise, it may take about one minute for the screen to appear when the server is rebooted.
The server starts the processor check, IO check, and initialization. Several messages appear showing the ID of the selected CPU/IO modules, information on the processor, detection of the keyboard and mouse, etc
A message appears at the lower left of the screen (shown below), prompting for startup of the BIOS setup utility SETUP.

You will need to start it when you want to modify the configuration for using the server. Unless this message appears together with an error message, you do not need to start the utility to modify the configuration. (If you wait for a few seconds, POST will go on automatically.)

To start the SETUP utility, press F2 while the above message is displayed.

When SETUP is completed, the server will reboot itself automatically and perform POST.
A message appears prompting for startup of the SAS BIOS setup utility.
When a built-in SAS controller is detected, a message will appear prompting for startup of the SAS BIOS setup utility. (If you wait for a few seconds, POST will go on automatically.)

If you press Ctrl + A, the SAS BIOS setup utility will start. However, you usually do not need to use the setup utility. For setting and parameter functions, see the Configuration section of this manual.

When SETUP is complete, the server will reboot automatically and perform POST from the start again.
The screen shows the ID numbers of the connected disk drive.
Upon completion of POST, the password entry screen appears prior to OS startup.
The password entry screen will appear after the normal termination of POST only if you have set a password in the BIOS setup utility SETUP.

You can enter a password up to three times. If you enter an incorrect password three times, the startup will be unsuccessful. In this case, turn off the power and then turn it on again after waiting 30 seconds to boot the server.

IMPORTANT: Set a password after the OS installation.
Upon completion of POST, the OS will start up.
