Troubleshooting Possible Problems - Analyze the alert by using the system event log (SEL) to identify the last error logged by the baseboard management controller. Use either the EFI shell command line interface (CLI) or if the optional management processor card is installed, use the MP commands to view the SEL. Step 3. At this point you will have a good idea about which area of the system requires further analysis. For example, if the symptom was "system will not power-up" then the initial troubleshooting procedure may have indicated a problem with the DC power supply not coming up after the power switch was turned on. Step 4. You have now reached the point where the failed Field Replaceable Unit (FRU or FRUs) have been identified and need to be replaced. You must now perform the specific remove and replace and verification steps. NOTE If multiple FRUs are identified as part of the solution, a fix cannot be guaranteed unless all identified failed FRUs are replaced. Step 5. There may be specific recovery procedures you need to perform to finish the repair. For example, if the display panel is replaced, you will need to restore customer specific information. Possible Problems This section contains example HP Server problems and their possible solutions. The system will not power-up. Step 1. Review the installation procedures for the server. Refer to Chapter 3, "Installing and Configuring." Step 2. Check all power connection cables. Step 3. Verify that power is available at the AC power receptacle. Check the receptacle output with another device. Step 4. Check the power supply fans to see if they are operating. The fans will operate off of the dc voltage generated by the power supply. Step 5. Check that the STBY (power good) LED located near the SCSI connector on the system board is illuminated. Step 6. Check all connections from the power supply to the power distribution module. Step 7. Verify that all cables and modules are correctly connected. Especially check the display panel connection. Step 8. If the system starts to power on and then power off, a voltage rail of the power supply may be out of specification. The BMC monitors voltages and prevents power on when power values are out of specification. 48 Chapter 4

Troubleshooting

—
Analyze the alert by using the system event log (SEL) to identify the last error logged by
the baseboard management controller. Use either the EFI shell command line interface
(CLI) or if the optional management processor card is installed, use the
MP
commands to
view the SEL.
Step 3.
At this point you will have a good idea about which area of the system requires further analysis.
For example, if the symptom was “system will not power-up” then the initial troubleshooting
procedure may have indicated a problem with the DC power supply not coming up after the power
switch was turned on.
Step 4.
You have now reached the point where the failed Field Replaceable Unit (FRU or FRUs) have been
identified and need to be replaced. You must now perform the specific remove and replace and
verification steps.
NOTE
If multiple FRUs are identified as part of the solution, a fix cannot be guaranteed
unless all identified failed FRUs are replaced.
Step 5.
There may be specific recovery procedures you need to perform to finish the repair. For example, if
the display panel is replaced, you will need to restore customer specific information.
Possible Problems
This section contains example HP Server problems and their possible solutions.
The system will not power-up.
Step 1.
Review the installation procedures for the server. Refer to Chapter 3, “Installing and Configuring.”
Step 2.
Check all power connection cables.
Step 3.
Verify that power is available at the AC power receptacle. Check the receptacle output with another
device.
Step 4.
Check the power supply fans to see if they are operating. The fans will operate off of the dc voltage
generated by the power supply.
Step 5.
Check that the STBY (power good) LED located near the SCSI connector on the system board is
illuminated.
Step 6.
Check all connections from the power supply to the power distribution module.
Step 7.
Verify that all cables and modules are correctly connected. Especially check the display panel
connection.
Step 8.
If the system starts to power on and then power off, a voltage rail of the power supply may be out of
specification. The BMC monitors voltages and prevents power on when power values are out of
specification.
