5. Pull the faceplate straight out of the slot.
Keep the faceplate in a safe area in case you need to replace it on
the slot again. The faceplate will keep any dust from getting into
the switch and will maintain proper airflow if the slot remains
empty.
6. Carefully slide the module into the slot until the module faceplate
makes contact with the switch, as displayed in Figure 36. Avoid
touching the module components.
