3024 Technician port connection invalid

Explanation

The code has detected more than one MAC address through the connection, or the DHCP has given out more than one address. The code thus believes there is a switch attached.

  1. Remove the cable from the technician port.
  2. (Optional) Disable additional network adapters on the laptop to which it is to connected.
  3. Ensure DHCP is enabled on the network adapter.
  4. If this was not possible, manually set the IP to 192.168.0.2
  5. Connect a standard Ethernet cable between the network adapter and the technician port.
  6. If this still does not work, reboot the node and repeat the above steps.
  7. This event will auto-fix once either no connection or a valid connection has been detected.
