Troubleshooting External Connections
Loose or improperly connected cables are the most likely source of problems
for the system, monitor, and other peripherals (such as a printer, keyboard,
mouse, or other external device). Ensure that all external cables are securely
attached to the external connectors on your system. See "Front-Panel
Features and Indicators" on page 14 and "Back-Panel Features and Indicators"
on page 19 for the front- and back-panel connectors on your system.
