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. Review all of the procedures in
"Safety Instructions" in your System Information Guide.
Observe the following precautions when working inside your system:
External Connections
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 cable connections can easily solve many problems. See Figure2-4 for the back-panel features and
connectors.
Checking Specific System Problems
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
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.
