You can solve many problems without outside assistance by following the troubleshooting procedures in
this documentation and on the World Wide Web.
This document describes the diagnostic tests that you can perform, troubleshooting procedures, and
explanations of error messages and error codes. The documentation that comes with your operating system
and software also contains troubleshooting information.

Diagnosing a problem

Before you call an approved warranty service provider, follow these procedures in the order in which they are
presented to diagnose a problem with your server.
Step 1. Return the server to the condition it was in before the problem occurred.
If any hardware, software, or firmware was changed before the problem occurred, if possible,
reverse those changes. This might include any of the following items:
• Hardware components
• Device drivers and firmware
• System software
• UEFI firmware
• System input power or network connections
Step 2. View the light path diagnostics LEDs and event logs.
The server is designed for ease of diagnosis of hardware and software problems.
• Light path diagnostics LEDs: See "Light path diagnostics LEDs" on page 115 for information
about using light path diagnostics LEDs.
• Event logs: See "Event logs" on page 120 for information about notification events and
diagnosis.
• 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 website
for documentation.
Step 3. Run Dynamic System Analysis (DSA) and collect system data.
Run Dynamic System Analysis (DSA) to collect information about the hardware, firmware, software,
and operating system. Have this information available when you contact your approved warranty
service provider. For instructions for running DSA, see the Dynamic System Analysis Installation
and User's Guide.
