25To install a filler panel in a switching fabric module slot:1. Loosen the captive screws on the ejector levers and rotate outward the ejector levers.2. Orient the filler panel with the side marked "Up" facing up. Hold the filler panel front panel nearthe ejector levers with one hand and support its bottom with the other. Place the filler panelbottom gently on the bottom guide rails of the chassis. Align the filler panel with the switchingfabric module slot. Push the filler panel slowly into the slot along the guide rails. See callout 1in Figure 23.Keep the filler panel parallel to the switching fabric module slot to avoid touching othercomponents in the chassis.3. As shown by callout 2 in Figure 23, continue to push the filler panel until the brakes on itsejector levers touch the slot edges tightly. Simultaneously rotate the ejector levers inward.4. Fasten the captive screws on the ejector levers.Figure 23 Installing a filler panel in a switching fabric module slot (S12516X-AF switch)(1) Push the filler panel slowly into the slot (2) Simultaneously rotate the ejector levers inward(3) Fasten the captive screws on the ejector leversRemoving a filler panel from a switching fabric module slot1. As shown by callout 1 in Figure 24, loosen the captive screws on the ejector levers.2. As shown by callout 2 in Figure 24, rotate outward the ejector levers. Then pull the filler panelpart way out of the slot.3. As shown by callout 3 in Figure 24, hold the filler panel by the top and bottom edges to pull thefiller panel out of the slot.Keep the removed the filler panel secure for future use.
