Removing and Installing a Line Card
Caution When you remove a line card, always use the ejector levers to ensure that the connector pins
disconnect from the backplane in the sequence expected by the router. Any card that is only
partially connected to the backplane can halt the router.
When you install a line card, always use the ejector levers to ensure that the card is correctly
aligned with the backplane connector; the connector pins should make contact with the
backplane in the correct order, indicating that the card is fully seated in the backplane. If a
card is only partially seated in the backplane, the router will hang and subsequently crash.
Removing a Line Card
If you are replacing a failed line card, remove the existing line card first, then install the new line card
in the same slot. To remove a line card, use Figure 10 as a reference and follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Disconnect and remove all interface cables from the ports; note the current connections of the cables to
the ports on the line card.
Step 3 Detach the line card cable-management bracket from the line card.
Step 4 Use a screwdriver to loosen the captive screw at each end of the line card faceplate. (See Figure 10a.)
