3. With a Phillips screwdriver, loosen the screws that secure the blank filler panel
covering the empty chassis slot, if present, and remove the filler panel.
4. Remove the module from its antistatic bag, being careful not to touch module
components, pins, leads, or solder connections.
5. Verify that the ejectors are in the open position, as shown in Figure 20.
6. Guide the module into the chassis by placing it between the guides of the
selected slot and pushing the module until it stops.
The module stops sliding when the ejectors make contact with the front
of the chassis.
CAUTION: If you meet strong resistance when attempting to seat the module using
the ejectors, remove it from the chassis and confirm that the slot is designed to hold
the module. Then verify, if applicable, that the module matches its corresponding
module (I/O module or line module). Also, be sure that you have aligned the top
and bottom edges in the correct matching tracks.
7. Insert the module into the midplane by simultaneously depressing both
ejectors (as shown in Figure 20) and exerting forward pressure on the module.
8. Tighten the module’s captive screws using a Phillips screwdriver. Alternately
turn each screw several times before tightening them completely to allow
the module to sit correctly.
