POST

POST (Power-On Self-Test) 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, DIMM, and processor (CPU).
POST also displays the start-up messages of various utilities during the operation.
Usually, you do not need to check the contents of POST. However, check messages displayed on POST in
the following cases.
•
When introducing a server
•
When you suspect a failure
•
When any error message is displayed

Explains how POST runs in order.
1. When the server is turned on, POST starts running.
Note
2. If Enabled is specified for Password On Boot in Security menu of SETUP, you will be prompted to
enter password after the POST is displayed. If you enter the incorrect password three times
consecutively, POST aborts. (You can no longer proceed.) In this case, power off the server, and power
it on.

Pressing the <ESC> key hides logo and displays the details of POST.
