New ContributorWhat do two yellow and two green blinking LEDs on the Intel N3000 PAC mean?
I was trying to install Intel N3000 FPGA PAC on the Supermicro 2029GP-TR server. The FPGA shows 2 yellow and 2 green leds blinking. This behaviour is not described in the manual. The FPGA does not show up in lspci on the server. What can be done?
Hi Anup,
Thanks for your help.
I will issue this info immediately to the related team for further procedure.
It might take approximately 3-4 days due to the weekend.
What I can help now, is highlighting your urgency on this case
Will get back to you as soon as possible.

Hi,
Not sure which LED you mention is blinking.
For detail, you may refer to Intel FPGA Programmable Acceleration Card N3000 DataSheet, page 17/31.- https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ds/ds-pac-n3000.pdf
- Table 8. does mention the LED behavior.
- For Connectivity LED
- Yellow means link up with link speed of 10G
- While Green means link up with speed of 25G
Do you see N3000 card enumerate in PCIe Bus ?
- I suggest you can try to remove the card from slot and check if the slot and edge connector is clean
- Please ensure that the server is running at maximum fan speed
Let me know if this helps.

Anup_AgarwalLEDs:
Currently both the activity LEDs (for QSFP A, B) blink in green and both the connectivity LEDs blink yellow (see attached image to verify). This is when nothing is connected to the QSFP ports.
Note we have the Intel N3000-N PAC. This does not support 10G configuration and the data sheet never mentions connectivity activity with yellow. Only mentions all 4 leds yellow in case of power/fan issue.
PCIE Enumeration:
We cannot see the accelerator in `lspci | grep -i accel` or `lspci -d :0b30`. The server is brand new, no dust. We ensured server fans are at full speed through IPMI as well as by inspecting server fan noise.
Environment:
We are using Centos 7.9 and linux kernel 4.19. We started with Centos 7.6 compiled linux kernel 4.19 with real-time patch following instructions in the user guide. Somewhere in between a `sudo yum update` caused update from Centos 7.6 to 7.9. We then installed the runtime stack for N3000-N.
I would imagine we should still be able to see the board in lspci irrespective of Centos 7.6 or 7.9. Am I wrong here? If so, I can reinstall Centos 7.6 and ensure we don't update to Centos 7.9.

Hi,
Appreciate you can share with me any printscreen or error code for
"We cannot see the accelerator in `lspci | grep -i accel` or `lspci -d :0b30"Besides, the error printscreen, I might need below item as well to narrow down the further
- to check the PCIe enumerate
$ lspci -vt - to check the FPGA accelerator port status
$ fpgainfo port - to check PHY status
$ fpgainfo phy - to check the Mac status
$ fpgainfo mac - BMC status
$ fpgainfo bmc
Looking forward to hear back from you

I am not sure what you mean by the error print screen. The system boots without any visible errors. But the N3000-N FPGA PAC does not show up in lspci/fpgainfo commands. The PAC LEDs blink in the fashion described above.
I have attached dmesg log instead of the error print screen.
I have also attached the lspci -vt output.
For all of the fpgainfo XXX commands. The output is the same: "No FPGA resources found."
The server is the same as in: https://community.intel.com/t5/Programmable-Devices/Is-the-Intel-N3000-FPGA-PAC-compatible-with-Supermicro-SYS/m-p/1319764#M81665
- to check the PCIe enumerate

One more thing, the user guide says:
we couldn't find these in the BIOS so skipped this step.

Please forgive typo in my reply:
Corrected line: This does not support 10G configuration and the data sheet never mentions connectivity LED with yellow.
