Removing and Installing a Line Card
Step2 Disconnect and remove all interface cables from the ports; note the current connections of the cables to
the ports on the line card.
Step3 Detach the line card cable-management bracket from the line card.
Step4 Use a screwdriver to loosen the captive screw at each end of the line card faceplate. (See Figure4a.)
Figure4 Line Card Removal and Installation
Caution When you remove a line card, always use the ejector levers to ensure that the line card connector pins
disconnect from the backplane in the logical sequence expected by the router. Any line card that is only
partially connected to the backplane can halt the router.
Step5 Simultaneously pivot the ejector levers away from each other to release the line card from the backplane
connector. (See Figure4b.)
Step6 Grasp the ejector levers and pull the line card halfway out of the slot.
Step7 Grasp the line card and gently pull it straight out of the slot, keeping your other hand under the line card
to guide it. (See Figure 4c.) Avoid touching the line card printed circuit board, components, or any
connector pins.
Step8 Place the removed line card on an antistatic mat, or immediately place it in an antistatic bag if you plan
to return it to the factory.
Step9 If the line card slot is to remain empty, install a line card blank (Product Number MAS-GSR-BLANK)
to keep dust out of the chassis and to maintain proper airflow through the line card compartment. Secure
the line card blank to the chassis by tightening its captive screws.
