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. SeeChapter 4, “Installing Additional Components and
Configuring.”
Step 2.
Check all power connection cables.
Step 3.
Verify that 200-240 VAC 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 the DC voltage generated by the
power supply.
Step 5.
Check that the Power LED on Front Control Panel is illuminated. See“Front Control Panel LEDs” on page 128.
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.
The system will not boot.
Step 1.
Examine the front panel LEDs for warning or fault indications. The system LED will be flashing yellow with a
warning indication and flashing red with a fault indication. See “Front Control Panel LEDs” on page 128.
Step 2.
Examine the QuickFind Diagnostic Panel for indications of specific warning or fault indications. The diagnostic
LEDs present patterns that categorize the source of the warning or fault. See “QuickFind Diagnostic Panel LEDs”
on page 130.
Step 3.
Display and examine the system event log (SEL) and forward progress log (FPL) for further information relating
to warning or fault isolation.
Step 4.
Review the firmware revisions of all firmware.
Step 5.
Use the MP command to cycle the system power:
pc off
,
pc on
.
Step 6.
Turn the server off, wait at least twenty seconds, then turn the server back on to see if the failure can be cleared.
Step 7.
Check that all DIMMs are seated properly.
Step 8.
Check that the DIMM configuration on the system board matches those approved. A minimum of one DIMM pair
must be installed.
Step 9.
Verify that the DIMMs are fully seated. When the DIMM is fully seated in the mating connector, the retaining
latches are closed (they should be flush with the front of the DIMM). If the latches are not closed, reseat the DIMM
fully by engaging the retaining latches and closing them fully.
Step 10.
Check that the processors are installed in the correct sockets and that each processor has a power pod installed.
Also verify that the processors are of the same type.
