Installing an S12500-X LPU
The S12500-X LPU edges and the ejector lever seats on the LPU slots have purple marks.
To install an S12500-X LPU:
1. As shown in Figure3-6, loosen the captive screws that secure the LPU to the protection box,
pull the ejector levers of the LPU outward, and pull out the LPU from the protection box. .
2. Orient the LPU with the PCB facing up. Hold the LPU by the front panel with one hand and
support its bottom with the other. Slide the LPU steadily into the target slot along the guide rails.
See Figure3-7.
Do not touch the components on the PCB.
Keep the LPU parallel to the slot to avoid touching other components in the chassis.
3. As shown by callout 2 in Figure3-7, pull the ejector levers outward when most of the LPU is
inserted into 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 Figure3-7, continue to push the LPU by its middle part on the front
panel until you cannot move it.
6. As shown by callout 4 in Figure3-7, push the ejector levers inward until they come in close
contact with the panel.
7. As shown by callout 5 in Figure3-7, fasten the captive screws to secure the LPU to the interface
module adapter.
