7 Solving Problems
This chapter helps you identify and solve problems that might occur while you are using the
system.
Resetting the System
To do this:
Clear system memory, restart POST, and reload the operating system.
Cold boot reset, which clears system memory, restarts POST, reloads the
operating system, and halts power to all peripherals.
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 all cables correctly connected and secured?
Are the processors fully seated in their slots on the baseboard?
Are all PCI add-in boards fully seated in their slots on the baseboard?
Are all switch and jumper settings on the baseboard 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 drive, is it properly formatted or configured?
Are all device drivers properly installed?
Are the configuration settings made with the SSU 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)?
Are the system power cords properly connected to the system and plugged into a NEMA
6-15R outlet for 100-120 V or for 200-240 V ?
Is AC power available at the wall outlet?
If these items are correct but the problem recurs, see "Specific Problems and Corrective
Actions" on page 73.
