Diagnostics
This section provides basic troubleshooting information to help you resolve some
common problems that might occur with your 2074.
Diagnostic Tools Overview
The following tools are available to help you identify and resolve hardware-related
problems:
v POST beep codes, error messages, and error logs
The power-on self-test (POST) generated beep codes and messages to indicate
successful test completion or the detection of a problem. See “POST” on
page 2-5 for more information.
v Diagnostic programs and error messages
The 2074 diagnostic programs are stored in upgradeable read-only memory
(ROM) on the system board. These programs are the primary method of testing
the major components of your 2074.
v Light path diagnostics
Your 2074 has light-emitting diodes (LEDs) to help you identify problems with
2074 components. These LEDs are part of the light-path diagnostics that are built
into your 2074. By following the
path of lights , you can quickly identify the type of
system error that occurred. See “Identifying Problems Using LEDs” on page 2-4
for more information.
v Troubleshooting charts
These charts list problem symptoms, along with suggested steps to correct the
problems.
