Error LEDs The following is an illustration of the system board LEDs. The system board has error LEDs that will help to locate the source of the error. Run the diagnostic programs to find out the cause of the error (see "Running the diagnostic programs" on page 122). Microprocessor 2 error LED Microprocessor 1 error LED Rear fan error LED Microprocessor 1 fan error LED Slot 1, PCI-Express error LED Slot 2, PCI-Express error LED Slot 3, PCI-Express error LED Slot 4, PCI-X error LED Microprocessor 2 fan error LED DIMM 8 error LED DIMM 7 error LED DIMM 6 error LED DIMM 5 error LED DIMM 4 error LED DIMM 3 error LED DIMM 2 error LED DIMM 1 error LED DIMM fan error LED Hard disk drive fan error LED Expansion slot fan error LED Slot 6, PCI error LED Slot 5, PCI-X error LED The computer is designed so that LEDs remain lit when the computer is connected to an ac power source but is not turned on, provided that the power supply is operating correctly. This feature helps you to isolate the problem when the operating system is shut down. Many errors are first indicated by a lit system-error LED on the front-panel assembly of the computer. If this LED is lit, one or more LEDs elsewhere in the computer might also be lit and can direct you to the source of the error. Before you work inside the computer to view the LEDs, read the safety information that begins on page vii and "Handling static-sensitive devices" on page 30. If an error occurs, view the computer LEDs in the following order: 1. Check the front-panel assembly on the front of the computer. If the system-error LED is lit, it indicates that an error has occurred. 2. Check the front and rear of the computer to determine whether any component LEDs are lit. 3. Remove the computer cover and look inside the computer for lit LEDs. Certain components inside the computer have LEDs that will be lit to indicate the location of a problem. For example, a DIMM error will light the LED next to the failing DIMM on the system board. Look at the system service label inside of the computer side cover, which gives an overview of internal components. This information can often provide enough information to correct the error.

The computer is designed so that LEDs remain lit when the computer is connected

to an ac power source but is not turned on, provided that the power supply is

operating correctly. This feature helps you to isolate the problem when the operating

system is shut down.

Many errors are first indicated by a lit system-error LED on the front-panel

assembly of the computer. If this LED is lit, one or more LEDs elsewhere in the

computer might also be lit and can direct you to the source of the error.

Before you work inside the computer to view the LEDs, read the safety information

that begins on page vii and “Handling static-sensitive devices” on page 30.

If an error occurs, view the computer LEDs in the following order:

Check the front-panel assembly on the front of the computer. If the system-error

LED is lit, it indicates that an error has occurred.

Check the front and rear of the computer to determine whether any component

LEDs are lit.

Remove the computer cover and look inside the computer for lit LEDs. Certain

components inside the computer have LEDs that will be lit to indicate the

location of a problem. For example, a DIMM error will light the LED next to the

failing DIMM on the system board.

Look at the system service label inside of the computer side cover, which gives

an overview of internal components. This information can often provide enough

information to correct the error.
