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), a NEMA 6-15R outlet (200-240 Vac), or an
UPS that meets the power specifications of the system?
!
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 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?
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
Processors
subsection of
Upgrading Your System
in chapter 4 for installation
instructions?
!
Are all DIMMs fully seated and installed correctly? Refer to the
DIMMs
subsection
