LED
Description and actions
12 PCIe slot 16 error LED LED on: an error has occurred to the PCIe slot the LED represents.
Complete the following steps:
1. Make sure the cable is connected to the appropriate downstream
PCIe riser, drive backplane, or OCP adapter.
2. Make sure both ends of the cable are securely seated in the PCIe
slots.
3. Replace the cable.
4. (Trained technician only) replace the system board. See “System
board replacement (trained technician only)” on page 214.
13 FPGA heartbeat error LED (green) This LED indicates power-on and power-off sequencing.
• LED blinking: the system is functioning properly, and no action is
necessary.
• LED not blinking: (trained technician only) replace the system board.
See “System board replacement (trained technician only)” on page
214.
14 UEFI valid LED The LED indicates the UEFI flash content verification result.
• LED on: UEFI flash contents verification passed.
• LED off: UEFI flash contents verification failed.
15 PFR error LED
The LED indicated the PFR (Platform Firmware Resilience) error.
• LED off: PFR/XCC/UEFI verification passed.
• LED on: one or more PFR/XCC/UEFI content verification failed, and
is unable to recover. (Trained technician only) replace the system
board. See “System board replacement (trained technician only)” on
page 214.
General problem determination procedures
Use the information in this section to resolve problems if the event log does not contain specific errors or the
server is inoperative.
If you are not sure about the cause of a problem and the power supplies are working correctly, complete the
following steps to attempt to resolve the problem:
1. Power off the server.
2. Make sure that the server is cabled correctly.
3. Remove or disconnect the following devices if applicable, one at a time, until you find the failure. Power
on and configure the server each time you remove or disconnect a device.
• Any external devices.
• Surge-suppressor device (on the server).
• Printer, mouse, and non-Lenovo devices.
• Each adapter.
• Hard disk drives.
• Memory modules until you reach the minimum configuration that is supported for the server.
See “Specifications” on page 1 to determine the minimum configuration for your server.
4. Power on the server.
