v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See Chapter 3, "Parts listing, Type 7996," on page 11 to determine which components are CRUs and which components are FRUs. v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician. Symptom Action The blade workstation does not turn on. 1. Check the function of the shared BladeCenter unit resources (see "Solving shared BladeCenter resource problems" on page 75). 2. Make sure that the power-on LED on the blade workstation control panel is flashing slowly. v If the power LED is flashing rapidly and continues to do so, the blade workstation is not communicating with the management-module; reseat the blade workstation and go to step 7. v If the power LED is off, the blade bay is not receiving power, the blade workstation is defective, or the LED information panel is loose or defective. 3. Check the power-management policies in the operating system for the blade workstation. 4. Check the management module log of the corresponding blade workstation for an error preventing the blade workstation from turning on. 5. Reseat the blade workstation. 6. If you just installed a device in the blade workstation, remove it and restart the blade workstation. If the blade workstation now starts, you might have installed more devices than the power to that blade bay supports. 7. (Trained service technician only) If you tried another blade workstation in the blade bay when checking the function of the shared BladeCenter unit resources and the other blade workstation worked, replace the system board assembly. 8. See "Solving undetermined problems" on page 80. The blade workstation turns off for no apparent reason. 1. Check the function of the shared BladeCenter unit resources (see "Solving shared BladeCenter resource problems" on page 75). 2. (Trained service technician only) If the microprocessor error LED is lit, replace the microprocessor. 3. (Trained service technician only) Replace the system board assembly. The blade workstation does not 1. Verify whether you are using an Advanced Configuration and Power Interface turn off. (ACPI) or non-ACPI operating system. 2. If you are using a non-ACPI operating system, complete the following steps: a. Turn off the blade workstation by pressing the power-control button for 4 seconds. b. If the blade workstation fails during POST and the power-control button does not work, remove the blade workstation from the bay and reseat it. 3. If the problem remains or if you are using an ACPI-aware operating system, complete the following steps: a. Check the power-management policies in the operating system for the blade workstation. b. (Trained service technician only) Replace the system board assembly. Chapter 5. Diagnostics 65

function
of
the
shared
BladeCenter
unit
resources
and
the
other
blade
workstation
worked,
replace
the
system
board
assembly.
8.
