Inserting a Line Module
Make sure that the power switch is off and that the system is unplugged from the power source. Then do as follows:
1Be sure the top and front covers are off.
2Locate the slot immediately to the right of the line module already installed. Notice the plastic channels at the top and bottom of the slots.
3Align the top and bottom edges of the line module to the channel openings so that the gold connectors face in and the components face out and to the right of the slot.

Hold the module by the plastic knob and slide it into the slot. See Figure 11.
Slide the module in until the gold connectors insert fully into the port at the back of the unit and the module snaps into place.
6Check that the module is held in place by the safety catch at the bottom of the slot. It should fit snugly against the bottom front of the module.
CAUTION: You may need to exert mild force to insert the module; however, do not use excessive force. If you have difficulty, remove the module from the slot, align the module properly, and try again.
If you still have difficulty, check the module and the channel for damage. If you find any damage, such as broken pieces or plastic chips, contact your equipment supplier for assistance. If there is no damage, try one more time; the module should snap into place.
