Troubleshooting a NIC
Steps
1 Run the appropriate diagnostic test. For more information, see the Using system diagnostics section for the available diagnostic tests.
2 Restart the appliance and check for any system messages pertaining to the NIC controller.
3 Check the appropriate indicator on the NIC connector:
• If the link indicator does not glow, the cable connected might be disengaged.
• If the activity indicator does not glow, the network driver files might be damaged or missing.
Install or replace the drivers as necessary. For more information, see the NIC documentation.
• Try another known good network cable.
• If the problem persists, use another connector on the switch or hub.
4 Ensure that the appropriate drivers are installed and the protocols are bound. For more information, see the NIC documentation.
5 Enter System Setup and confirm that the NIC ports are enabled on the Integrated Devices screen.
6 Ensure that all the NICs, hubs, and switches on the network are set to the same data transmission speed and duplex. For more
information, see the documentation for each network device.
7 Ensure that all the NICs and switches on the network are set to the same data transmission speed and duplex. For more information,
see the documentation for each network device.
8 Ensure that all network cables are of the proper type and do not exceed the maximum length.
