Chapter 5. Diagnostics

Diagnosing a problem

Before you contact Lenovo or an approved warranty service provider, follow these procedures in the order
in which they are presented to diagnose a problem with your server:
1. Determine what has changed.
Determine whether any of the following items were added, removed, replaced, or updated before the
problem occurred:
• UEFI
• Device drivers
• Firmware
• Hardware components
• Software
If possible, return the server to the condition it was in before the problem occurred.
2. Collect data.
Thorough data collection is necessary for diagnosing hardware and software problems.
a. Document error codes and system-board LEDs.
• System error codes: See the Installation and User Guide for information about a specific error
code.
• See the Installation and User Guide for the location of the system-board LEDs.
• Software or operating-system error codes: See the documentation for the software or
operating system for information about a specific error code. See the manufacturer's Web site for
documentation.
• Light path diagnostics LEDs: See the Installation and User Guide for information about LEDs
that are lit.
b. Collect system data.
Run Dynamic System Analysis (DSA) Preboot diagnostics program to collect information about the
hardware, firmware, software, and operating system. Have this information available when you
contact Lenovo or an approved warranty service provider. See http://www.lenovo.com/support for
the instructions to run the DSA Preboot program.
If you need to download the latest version of DSA Preboot, go to http://www.lenovo.com/support or
