Install the MPO Coupler Panel

1. Follow safety and ESD precautions.

   See Safety and ESD Precautions.

2. If installing a replacement module within the coupler panel, do the following:
   1. Insert the module fully until it is completely seated, and the mushroom heads have receeded.
   2. Connect the internal fiber cables to the correct ports, per cable labels, to the replacement module.

      The correct ports are the ones that face the front of the modular system when the coupler panel is installed. These cables go through the second opening in the coupler panel. Refer to the labels on the cables.

3. Carefully push the coupler panel back into the slot, keeping clear of the fiber cables.
4. Using a No. 3 Phillips screwdriver, insert the four screws to attach the coupler panel to its mounting brackets.
5. Reconnect the external cables, including any external cables, to the ports on the coupler panel.

   For any custom external cables, refer to the notes created earlier to reconnect cables to their previous locations.

6. Resume applications that were stopped for the service.
