Network controller is installed but not working
The network controller is not working.
-
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.
-
Verify that no loose connections exist.
For more information, see Loose connections.
-
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.
- Verify that the network cable is working by replacing it with a known functional cable.
-
Verify that a software issue did not cause the failure.
For more information, see the operating system or server documentation.
- Verify that the controller is enabled in the Aptio Setup Utility.
-
Verify that the system ROM and controller drivers are current.
For more information, see Keeping the system current.
- Verify that a valid IP address is assigned to the controller and that the configuration settings are correct.
- Verify that the network controller is fully seated into the applicable (or supported) PCIe slot.
