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
■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
■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.
