Diagnostic programs and error messages
•
The device diagnostic programs are stored in ROM on the system board.
These programs are the primary method of testing the major components of
your device. See the
page 6-7 for more information.
Light Path Diagnostics
•
Your device has LEDs to help you identify problems with device components.
These LEDs are part of the Light Path Diagnostics that are built into your
device. By following the path of LEDs, you can quickly identify the type of
system error that occurred. See the
page 6-21 for more information.
Error symptom charts
•
These charts list problem symptoms, along with suggested steps to
correct the problems. See the
for more information.
When you power up the device, it performs a series of tests to check the operation
of device components and some of the hardware options installed in the device.
This series of tests is called the power-on self-test, or POST.
If POST finishes without detecting any problems, a single beep sounds, and the
first screen of your operating system or application program appears.
If POST detects a problem, more than one beep sounds, and an error message
appears on your screen. See the
"POST Error Codes" section on page 6-49
If you have a power-up password or administrator password set, you must enter
the password and press Enter when prompted, before POST will continue.
