POST

Power-On Self-Test (POST) is a self-diagnostic program stored in the server as standard. POST
automatically runs immediately after the server is turned on and checks the motherboard, memory, and
processor (CPU). POST also displays the start-up messages of different utilities during the operation.
Usually, you do not need to check the result of POST. However, check messages displayed at POST in
the following cases.
• When introducing a server
• If you suspect a failure
• If you hear beep many times during the time between power on and OS startup
• If an error message is displayed

enter password after the logo is displayed.
If you enter the incorrect password three times consecutively, POST stops and you can no longer
proceed. Turn off the server and restart.
