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
Problems that occur at initial system startup are
usually caused by incorrect installation or
configuration. 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 available at the wall outlet?
■
Is the main power switch located on the top of the
power supply cage at the rear of the system in the
ON position?
■
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 EISA/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 jumper 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.
