What to do if the Nvidia Computer Hardware DPU no longer works?
If the DPU has stopped working, try reseating it in its current slot or a different one. You may also want to try using another cable. If that doesn't work, reinstall the drivers, as the network driver files may be damaged or deleted. As a last resort, reboot the server.
How to fix Nvidia Computer Hardware server unable to find the DPU?
If the server is unable to find the DPU, ensure that the DPU is placed correctly and that the DPU slot and the DPU are compatible. If issues persist, install the DPU in a different PCI Express slot. Consider using the drivers that came with the DPU or download the latest. Also, make sure your motherboard has the latest BIOS. Finally, try rebooting the server.
What to do if Nvidia Computer Hardware DPUs stopped working after installing another DPU?
If DPUs stopped working after installing another DPU, try removing and re-installing all DPUs. Also, check that cables are connected properly. Ensure that your motherboard has the latest BIOS.
Why is the Nvidia Computer Hardware link indicator light off?
If the link indicator light is off, try another port on the switch. Ensure the cable is securely attached and that you are using the proper cables that do not exceed the recommended lengths. Also, verify that your switch and DPU port are compatible.
Why is the Nvidia Computer Hardware link light on, but with no communication established?
If the link light is on, but with no communication established, verify that the latest driver is loaded. Also, check that both the DPU and its link are set to the same speed and duplex settings.
