POST error messages

The Power-On Self Text (POST) is a series of diagnostic tests that runs automatically when the
workstation is powered on.
Audible and visual messages occur before the operating system starts if the POST encounters a
problem. POST checks the following items to ensure that the workstation system is functioning properly:
Keyboard
DIMMs
Diskette drives
All mass storage devices
CPUs
Controllers
Fans
Temperature sensors
Cables (front/rear panels, audio, and USB ports)
The table shown next describes the POST error messages.
