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 Figure 1-1 for the front-panel
connectors and Figure 1-2 for the back-panel connectors on your system.
