Power On Self Test (POST) and Error Messages

POST is a series of diagnostic tests that runs automatically when the system is turned on. An audible, visual, or both
message occurs if the POST encounters a problem. POST checks the following items to ensure that the workstation system
is functioning properly:
• Keyboard
• Memory modules
• Diskette drives
All SATA and SCSI mass storage devices
•
• Processors
• Controllers
NOTE: If the Power-On Password is set, a key icon appears on the screen while POST is running. You must enter the
password before continuing.
