IMPORTANT:
Keep filler panels installed on unused LPUs.
No interface module adapter is required to install an S12500X-AF LPU on the switch.
The S12500X-AF LPU ejector levers and the ejector lever seats on the LPU slots have purple marks.
Installing an LPU with common ejector levers
1. As shown by callout 1 in Figure 8 , remove the filler panel from the target LPU slot.
Keep the removed filler panel secure for future use.
2. As shown by Figure 8 , orient the LPU upside up based on the orientation of characters on the
LPU. Holding the LPU by the front panel with one hand and supporting the bottom with the other,
push the LPU steadily into the slot along the guide rails.
Keep the LPU parallel to the slot to avoid touching other components in the chassis.
3. As shown by callout 2 in Figure 8 , pull the ejector levers of the LPU outward when most part of
the LPU is inserted in the slot.
4. Push the LPU until the brakes on its ejector levers touch the slot edges tightly.
5. As shown by callout 3 in Figure 8 , Continue to push the LPU by its middle part on the front panel
until you cannot push it further.
6. As shown by callout 4 in Figure 8 , push the ejector levers inward until they come in close
contact with the front panel.
7. As shown by callout 5 in Figure 8 , fasten the captive screws on the LPU.
