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:
! Are the system power cords properly connected to the system and plugged into a
NEMA 5-15R outlet (100-120 Vac) or a NEMA 6-15R outlet (200-240 Vac)?
! 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 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.
! Are the configuration settings in BIOS Setup and the System Setup Utility (SSU)
correct? For information about running these utilities, refer to the “Configuring Your
System” chapter.
If the above items are all correct, but the problem reoccurs, refer to “Additional
Troubleshooting Procedures” in this chapter.
