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, review the following checklist.
Checklist

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?
