Cisco Systems 12000 series specifications Inserting and Removing the Blank Filler

Removing and Installing a Line Card

Step 1 Choose an available pair of slots for the line card, and verify that the fiber-optic interface cables for the line card are long enough for you to reach the line card ports and connect the line card to any external equipment.

Step 2 Grasp the faceplate of the blank filler with one hand and place your other hand under the blank filler; position the card for insertion into the rightmost card cage slot of the pair of slots to be used by the ATM line card.

Step 3 Carefully slide the blank filler into the slot, making sure that the runners on the top and bottom of the blank filler are positioned within the card cage slot runners.

Step 4 Use a screwdriver to tighten the captive screw on each end of the blank filler faceplate to ensure proper EMI shielding and to provide proper ventilation for the ATM line card. These screws must be tightened to meet electromagnetic interference (EMI) specifications. (See Figure 8.)
