Diagnostic tools overview
The following tools are available to help you diagnose and solve hardware-related
problems:
v POST beep codes
The power-on self-test beep codes indicate the detection of a problem.
– One beep indicates successful completion of POST, with no errors.
– More than one beep indicates that POST detected a problem. Error messages
also appear during startup if POST detects a hardware-configuration problem.
See “POST beep codes” and the Hardware Maintenance Manual, which is
available on the Lenovo Support Web site, for more information.
v Troubleshooting tables
These tables list problem symptoms and steps to correct the problems. See
“Troubleshooting tables” on page 72 for more information.
v Diagnostics DVD
The Diagnostics DVD provided with your server contains the diagnostic programs
for testing the major components of the server. For additional information about
the Diagnostics DVD, see the Hardware Maintenance Manual, which is available
on the Lenovo Support Web site..
v System-board error LEDs
An LED on the system board might be lit to help isolate an error that is indicated
by the system-error LED on the front of the server. For more information, see
“System-board LEDs” on page 85.

POST emits one beep to signal a successful completion. If POST detects a problem
during startup, other beep codes might occur. Use the following beep code
descriptions to help diagnose and solve problems that are detected during startup.
Note: See the Hardware Maintenance Manual, which is available on the Lenovo
Support Web site, for more information about the POST beep codes.
