How do I troubleshoot my network connections?

If you cannot connect the server to a router or if you have lost the connection, you cannot continue until you see a link light on the network adapter. It is recommended that your server be connected to a router that can access the Internet during installation, so that updates can be downloaded, but it is not required.

To troubleshoot your network connections, do the following:

  • Check the network cables to ensure that they are properly installed.

  • Replace the network cables.

  • Verify that the router is turned on and is working properly.

  • Reboot the router.


After your server is properly connected to the router, do not disconnect the network adapter from the router during installation. You must have a link light for your network connection during the entire installation.
