This is a new concept in the EM configuration. A chain allows multiple EMs to be chained together to act as a single EM. This is required for CIP. This is accomplished by setting an EMs Source Link EM and/or Destination Link EM. If either is set the this EM will hold/suspend/restart/resume with its links but it will not start/stop with them; that must be done directly.
