Removal and Installation
3. To remove the module ejector levers:
a. Set the optical chassis so the module ejector levers are facing you.
b. Remove both T-10 Torx drive screws that attach the ejector lever to the
optical chassis. (See Figure 4-19.)
c. Remove both brass washers, ejector lever and ejector spring.
4. Reinstall the ejector levers and module slot doors as follows:
a. Place the ejector spring over the PEM nut standoffs (pivot and slider).
One spring arm is positioned next to the ejector lever spring tab. The other
spring arm is positioned to the left-side of the stud post.
b. Place the ejector lever over the ejector spring and PEM nut standoffs
(pivot and slider).
NOTE.
Make sure the ejector lever is positioned correctly. The ejector lever
has a dimple protruding to accommodate the snap-on handle. When installing
the ejector lever this dimple must be facing up from the optical chassis. (See
Figure 4-19.)
c. Place brass shoulder washers over both pivot and slider mounting
positions.
d. Install both T-10 and Torx drive screws to attach the pivot and slider
mounting positions.
e. Move the left spring arm to the right-side of the stud post. The right spring
arm must be on the left of the lever tab. (See Figure 4-20 on page 4-44.)
