Dell™PowerEdge™650SystemsInstallationandTroubleshootingGuide
If your system is not working as expected, begin troubleshooting using the procedures in this section. This section guides you through initial checks and
procedures that can solve basic system problems and provides troubleshooting procedures for components inside the system. Before you start any of the
procedures in this section, perform the following steps:
l Read "Running the System Diagnostics" for information about running diagnostics.
Safety First—For You and Your System
To perform certain procedures in this document, you must remove the system cover and work inside the system. While working inside the system, do not
attempt to service the system except as explained in this guide and elsewhere in your system documentation.
External Connections
Loose or improperly connected cables are the most likely source of problems for the system, monitor, and other peripherals (such as a keyboard, mouse, or
other external device). Ensure that all external cables are securely attached to the external connectors on your system. See Figure2-2 for the back-panel
connectors on your system. See "I/O Connectors" for more information about the functionality of each connector type.
Checking Specific System Problems
1. Turn off the system and attached peripherals. Disconnect all the power cables from their electrical outlets.
2. If the system is connected to a power distribution unit (PDU), turn the PDU off and then on again.
If the system is not receiving power, plug it into another electrical outlet. If it still is not receiving power, try another PDU.
3. Reconnect the system to the electrical outlet or PDU.
