Running the diagnostic programs
To run the DSA Preboot diagnostic programs, complete the following steps:
1. If the server is running, turn off the server and all attached devices.
2. Turn on all attached devices; then, turn on the server.
3. When the prompt
<F2> Diagnostics
is displayed, press F2.
Note: The DSA Preboot diagnostic program might appear to be unresponsive for an unusual length of
time when you start the program. This is normal operation while the program loads.
4. Optionally, select Quit to DSA to exit from the stand-alone memory diagnostic program.
Note: After you exit from the stand-alone memory diagnostic environment, you must restart the server
to access the stand-alone memory diagnostic environment again.
5. Select gui to display the graphical user interface, or select cmd to display the DSA interactive menu.
6. Follow the instructions on the screen to select the diagnostic test to run.
If the diagnostic programs do not detect any hardware errors but the problem remains during normal server
operations, a software error might be the cause. If you suspect a software problem, see the information
that comes with your software.
A single problem might cause more than one error message. When this happens, correct the cause of the
first error message. The other error messages usually will not occur the next time you run the diagnostic
programs.
Note: If multiple error codes or LEDs indicate a microprocessor error, the error might be in a microprocessor
or in a microprocessor socket. See “Microprocessor problems” on page 59 for information about diagnosing
microprocessor problems.
If the server stops during testing and you cannot continue, restart the server and try to run the diagnostic
programs again. If the problem remains, replace the component that was being tested when the server
stopped.
For a list of diagnostic messages, see Chapter 5 “Diagnostics” on page 21.
Advanced Settings Utility program
The Advanced Settings Utility (ASU) program is an alternative to the Setup Utility for modifying UEFI settings.
Use the ASU program online or out of band to modify UEFI settings from the command line without the need
to restart the system to access the Setup Utility.
You can also use the ASU program to configure the optional remote presence features or other IMM settings.
The remote presence features provide enhanced systems-management capabilities.
