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 Dell 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.

WARNING:

The power supplies in this system produce high voltages and energy hazards, which can cause bodily harm. Only trained service

technicians are authorized to remove the system cover 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 cover.

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

Figure 2-3

for the back-panel features and connectors.

Checking Specific System Problems

1. Turn off the system, including any attached peripherals. Disconnect all the power cables from their electrical outlets.

2. If the system is connected to a PDU, turn the PDU off and then on again.

If it 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.
