System board LEDs The following illustration shows the system-board LEDs. Microprocessor 2 fan error LED 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 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 Figure 5. System board LEDs Slot 5, PCI-X error LED Each error LED is lit to indicate a problem with a specific component. The error LEDs remain lit until the error log is cleared, this prevents false errors from going undetected. For information about how to correct the problems that are indicated by the error LEDs, see "System board error LEDs" on page 134. Chapter 1. Introduction 11
