Safety First—For You and Your System
The procedures in this guide require that you 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.
CAUTION:
The power supplies in this system may produce high voltages and energy hazards, which can cause bodily harm. Only trained service
technicians are authorized to open the system and access any of the components inside the system.
CAUTION:
See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document before performing
any procedure which requires you to open the system.
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 keyboard, mouse, or other external equipment). A quick check of all the switches, controls, and cable connections can easily solve these
problems. See
Figure 2-3
for the back-panel features and connectors.
Checking Basic System Problems
1. If the system is not receiving power, check that a power cable is attached to power connector PS1 on the system back panel (see Figure 2-3).
If your system has two power supplies, also check that a second power cable is attached to power connector PS2.
2. Turn off the system, including any attached peripherals, and disconnect all power cables from their electrical outlets.
3. If the system is connected to a PDU, turn the PDU off and then on again.
