746 Technician port connection invalid.

Explanation

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

User response

  1. Disconnect Technician port from a network switch.
  2. If you need to connect to the system for initialization or service, direct-connect technician laptop to the technician port without using network switches.
