Network controller is installed but not working

Symptom

The network controller is not working.

Action
  1. Check the network controller LEDs for statuses that indicate the source of the issue.

    For more information about LEDs, see the network controller or server documentation.

  2. Verify that no loose connections exist.

    For more information, see Loose connections.

  3. Verify that the correct cable type is used for the network speed or that the correct SFP or DAC cable is used.

    For dual-port 10GB network devices, both SFP ports should have the same media (for example, DAC cable or equivalent SFP+ module). Mixing different types of SFP (SR/LR) on a single device is not supported.

  4. Verify that the network cable is working by replacing it with a known functional cable.
  5. Verify that a software issue did not cause the failure.

    For more information, see the operating system or server documentation.

  6. Verify that the controller is enabled in the Aptio Setup Utility.
  7. Verify that the system ROM and controller drivers are current.

    For more information, see Keeping the system current.

  8. Verify that a valid IP address is assigned to the controller and that the configuration settings are correct.
  9. Verify that the network controller is fully seated into the applicable (or supported) PCIe slot.
