COMPLETE THE FOLLOWING STEPS TO PERFORM THE CHECKOUT
PROCEDURE.
1. Turn off the server and all external devices, if any are attached.
2. Check all cables and power cords.
3. Set all display controls to the middle position.
4. Turn on all external devices.
5. Turn on the server.
6. Record any POST error messages that are displayed on the screen. If
an error is displayed, look up the first error in "POST error codes" on
page 79.
7. Check the information LED panel blade error LED; if it is lit, see
"Diagnosing problems using the light path diagnostics feature" on page
27.
8. Check the system-error log. If an error was recorded, see Chapter 6,
"Symptom-to-FRU index," on page 77.
9. Start the diagnostic programs.
10. Check for the following responses:
v One beep
v Readable instructions or the main menu
002
DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?
NO. Find the failure symptom in Chapter 6, "Symptom-to-FRU index," on
page 77.
YES. Run the diagnostic programs. If necessary, see "Diagnostic programs
and error messages" on page 25.
If you receive an error, see Chapter 6, "Symptom-to-FRU index," on page
77.
If the diagnostic programs were completed successfully and you still
suspect a problem, see "Undetermined problems" on page 101.
The beep codes indicate that the power-on self-test (POST) or the baseboard
management controller (BMC) have detected a problem during startup. Error
messages also appear during startup if POST detects a hardware-configuration
problem. See "Beep codes" on page 77 for more information.
Real Time Diagnostics tests the major components of the BladeCenter unit,
including the managemente modules, switch modules, CD-ROM drive, diskette
drive, and the blade server, while the server operating system is running. Real
Time Diagnostics can either be plugged into an existing IBM Director
environment or installed without IBM Director present. For documentation and
download information for the Real Time Diagnostics, go to
http://www.ibm.com/servers/xseries/systems_management/xseries_sm.html.
Notes:
1. As of the date of this document, the IBM Director CD does not come with the
BladeCenter T unit. If you have the BladeCenter T unit, see the IBM
Eserver BladeCenter HS40 Type 8839 Installation and User's Guide for
more information.
