5 Troubleshooting

This chapter provides troubleshooting instructions for maintaining the server.

Troubleshooting Tips

CAUTION:
(including disk drives) removed. Damage to server components can result due to
improper cooling airflow.
If you do not replace the top cover within 30 minutes, the server automatically shuts
off.
For problems with an optional disk array controller board, refer to the appropriate
manuals provided with the array controller.
For general information on Hewlett Packard Enterprise server products, see the
Hewlett Packard Enterprise website at http://www.hpe.com.

Possible Issues

This section contains example server problems and their possible solutions. For details
on the iLO MP commands, see the HPE Integrity and HPE 9000 iLO Operations
Guide.

The System Does Not Power-On

1. Review the installation procedures for the server.
2. Check all power connection cables.
3. Verify that the Power On/Off LED on the control panel is illuminated. If not
illuminated check the AC power. If the LED is flashing yellow, the server is in DC
standby. Check the power status with the iLO MP PS command. If the Power
On/Off LED is illuminated steady green, the DC power supply is on.
4. Check the normal operation of the power supply and fans. The iLO MP PS
command interrogates the status of the power subsystem.
5. Check the system board diagnostic LEDs for proper operation. See System Board
Diagnostic LEDs later in this chapter.
6. Verify that both LEDs of the power supply (visible behind bezel) are illuminated.
The upper LED indicates presence of proper AC voltage, and the lower indicates
that the DC power is good.
7. Verify that all cables and modules are correctly connected. Check the display
panel connection. Use the iLO MP VFP command to verify a match of control
panel LED indications.
8. If the server starts to power on and then power off, a voltage rail of the power
supply might be out of specification. The BMC monitors voltages and prevents
power on when power values are out of specification. If this occurs, check the
SEL logs for an alert with a high level (alert level 5 or alert level 7). Also check
the power subsystem with the iLO MP PS command.

The System Does Not Boot

1. Examine the display panel LEDs for warning or fault indications. The server LED
flashes yellow with a warning indication and flashes red with a fault indication. If
this occurs, check the SEL logs for additional information on the alert.
Do not operate the server for more than 30 minutes with any cover
