5. Connect and route the cables.
   1. Reconnect the power cords and other cables to the rear of the node.
   2. Route the cables and power cords on the CMA and secure them with cable ties or hook-and-loop fasteners.
   Notes:

   • The location of the cable straps can vary in different systems.
   • Use the cable straps that are provided on the rear of the system to retain the cables and prevent them from sagging.
   • Allow slack in all of the cables to avoid tension in the cables as the CMA moves.
