3. Review the locations of PCIe adapter slots and the service indicators for the PCIe adapter that you
want to service. The PCIe adapters are viewed at the rear of the system.
Figure 22 on page 30 and Figure 23 on page 31 show the locations of the PCIe adapter in a system
and the locations of the light-emitting diodes (LEDs) for the PCIe adapter.
The PCIe adapter has two LEDs that indicate the status:
• A power/activity LED (green)
• An error and identify function LED (amber)
The status of the LEDs are as follows:
• (B) Indicates that the PCIe adapter is operating correctly. The green power LED (top LED) is lit solid
and the amber fault LED (bottom LED) is off.
• (C) Indicates that the PCIe adapter is not operating correctly. The green power LED (top LED) is lit
solid and the amber fault LED (bottom LED) is lit solid.
• (D) Indicates the faulty or failed PCIe adapter was selected by using the identify function. The
green power LED (top LED) might or might not be lit and the amber fault LED (bottom LED) is
flashing.
Attention: If the PCIe adapter is operating correctly, then the Activity LED is ON (green) and
the Error amber LED is OFF, as shown in (B). Do not attempt to remove a working PCIe
adapter.
