Initial System Startup
Problems that occur at initial system startup are usually caused by incorrect installation or
configuration. Hardware failure is a less frequent cause.
Initial System Startup Checklist
• Are the power supplies turned on? Check the switches on the back of the chassis.
• Are all cables correctly connected and secured?
• Are the processors or processor termination board fully seated in their slots on the server
board?
• Are all add-in PCI boards fully seated in their slots on the server board?
• Are all jumper settings on the server board correct?
• Are all jumper and 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—for example, two add-in boards sharing the same interrupt.
• Are all DIMMs installed correctly?
• Are all peripheral devices installed correctly?
• If the system has a hard disk drive, is it properly formatted or configured?
• Are all device drivers properly installed?
• Are the configuration settings made in Setup correct?
• Is the operating system properly loaded? Refer to the operating system documentation.
• Did you press the system power on/off switch on the front panel to turn the server on (power on
light should be lit)?
• Is DC power available?
• Are all integrated components from the tested components lists? Check the tested memory and
chassis lists, as well as the supported hardware and operating system list on the IBM Customer
Support website.
