Dell™PowerEdge™6600SystemsInstallationandTroubleshootingGuide
If your system is not working as expected, begin troubleshooting by using the procedures in this section. This section guides you through some 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, take the following steps:
l Read the "Safety Instructions" in your System Information document.
l Read "Running the System Diagnostics" for information about running diagnostics.
l Get the key to the system's keylock and back cover.
Safety First—For You and Your System
The procedures in this guide require that you remove the 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. Always follow the instructions closely. Make sure to review all of the
procedures in "Safety Instructions" in your System Information document.
Working inside the system is safe—if you observe the following precautions.
Before You Begin
Before you perform any of the procedures, ensure that the following components are securely and properly installed:
l Power cables
l Cables to external devices, such as monitor, mouse, and keyboard
l Microprocessor tray
External Connections
Improperly set switches, controls, and loose or improperly connected cables are the most likely source of problems for the system, monitor, or other
peripherals (such as a printer, keyboard, mouse, or other external equipment). A quick check of all the switches, controls, and cable connections can easily
solve these problems. See Figure2-3 for the back-panel features and connectors.
Checking Specific System Problems
1. Turn off the system, including any attached peripherals, and disconnect all power cables from their electrical outlets.
2. If the system is connected to a PDU, turn the PDU off and then on again.
If the PDU 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.
4. Is the monitor working properly?
