Problem Solving 5-3
Troubleshooting Checklists
The following subsections provide troubleshooting checklists for
problems that occur at initial system startup, when you run new
application software, and after the system hardware and software have
been running correctly.
Initial System Startup
Incorrect installation or configuration usually causes problems that
occur at initial system startup. Hardware failure is a less frequent
cause. If you have problems during initial system startup, check the
following:
Is the system power cord properly connected to the system and
plugged into a NEMA 5-15R outlet (100-120 V ac) or a NEMA 6-15R
outlet (200-240 V ac)?
Is AC power available at the wall outlet?
Is the power on/off push-button switch on the front panel in the ON
position (power on LED should be lit)?
Are all cables correctly connected and secured?
Are all the PCI/ISA option boards fully seated in their connector slots
on the system board?
Are all jumper settings on the system board correct? For jumper
information, see the “Configuring Your System” chapter?
Are all jumpers and switch settings on option boards and peripheral
devices correct? To check these settings, see the respective
appendices. If applicable, ensure that there are no conflicts; for
example, two option boards sharing the same interrupt.
Are the processors fully seated in their slots on the system board?
Refer to the “Upgrades and Options” chapter for installation
instructions?
Are all DIMMs fully seated and installed correctly? Refer to the
“Upgrades and Options” chapter for installation instructions?
Are all option boards and disk drives installed correctly? Refer to the
“Upgrades and Options” chapter.
Is the system hard disk drive properly formatted or defined?
Is the operating system properly loaded? Refer to the operating
system documentation.
Are all drivers properly installed? For information about installing
drivers, refer to your Network Operating System Configuration Guide.
