106 5 System troubleshooting Initial troubleshooting checklist Use the checklist below to eliminate possible causes for the problem you are encountering. • AC power is available at the wall outlet? • Is the power supply module properly installed? • Is the system power cord properly plugged into the power supply module socket? and connected to a NEMA 5-15R outlet for 100-120 V or a NEMA 6-15R outlet for 200-240 V? • Are all peripheral cables correctly connected and secured? • Did you press the system power button to turn the server on (power on indicator should be lit green)? • Are all device drivers properly installed? • Are hard disk drive(s) properly formatted and configured? • Are the BIOS configuration settings in the BIOS Setup Utility correct? • Is the operating system properly loaded? Refer to the operating system documentation. • Are all hardware components compliant with the tested components lists? • Are all internal cables correctly connected and secured? • Is the processor properly seated in its mainboard socket? • Are all standoffs in the proper location and not touching any components, causing a potential short? • Are all add-in expansion cards fully seated in their mainboard slots? • Are all system jumpers correctly set? • Are all switch settings on add-in boards and peripheral devices correct? To check these settings, refer to the manufacturer's documentation that comes with them. If applicable, ensure that there are no conflicts (e.g., two add-in boards sharing the same interrupt).
