What to do if my Nvidia Network Hardware DPU no longer works?
If your Nvidia Network Hardware DPU has stopped working, try reseating it in its slot or in a different slot. You can also try using another cable. Reinstalling the drivers may also help, as the network driver files may be damaged or deleted. Rebooting the server is also recommended.
How to fix Nvidia Network Hardware server unable to find the DPU?
If the server is unable to find the Nvidia Network Hardware DPU, ensure that the DPU is placed correctly and that the DPU slot and the DPU are compatible. If the issue persists, install the DPU in a different PCI Express slot. Also, use the drivers that came with the DPU or download the latest, and ensure your motherboard has the latest BIOS. Finally, try rebooting the server.
What to do if Nvidia Network Hardware DPUs stopped working after installing another DPU?
If the Nvidia Network Hardware DPUs stopped working after installing another DPU, try removing and reinstalling all DPUs. Check that cables are connected properly and that your motherboard has the latest BIOS.
Why is the link indicator light off on my Nvidia Network Hardware?
If the link indicator light is off on your Nvidia Network Hardware, 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.
What to do if Nvidia Network Hardware link light is on, but with no communication established?
If the Nvidia Network Hardware link light is on, but no communication is established, ensure that the latest driver is loaded. Also, check that both the DPU and its link are set to the same speed and duplex settings.
