Installing a Line Card
Step 5 Use both hands while inserting an LC. Use one hand on the faceplate and the other hand along the base of the
LC to guide it into a slot.
Step 6 Press the OIR buttons to release the ejectors.
Caution
Step 7 Make sure that the ejector levers are oriented properly to engage with the pin as the LC slides into the slot.
Carefully slide the LC into the slot until the ejector levers engage the catches, and then stop.
Step 8 Simultaneously pivot the ejector levers toward the faceplate of the LC. Do not force the LC; the ejector levers
properly seat the LC against the backplane.
Note
Step 9 Use a number-2 Phillips screwdriver or number-2 common (flat-head) screwdriver to tighten the captive
screws next to each LC ejector lever to ensure proper EMI shielding and prevent the LC from becoming
partially dislodged from the backplane. Tighten the captive screws using 10.60 pound/force (lbf) inch (1.20
Nm torque).
Step 10 Before attaching the vertical cable management bracket, ensure that the LC has been installed properly. See
the Verifying the Installation of a Line Card, on page
Step 11 Attach the vertical cable management bracket to the faceplate of the LC using the two screws that came with
it. The dark gray arm should be facing up, and the light gray arm should be facing down.

When adjusting the ejector levers, avoid hitting the top and bottom fiber management features and
doors.
If the captive screws are difficult to tighten, ensure that each ejector lever is properly secured to each
catch and that the LC is properly seated in the slot.
