Cisco Cisco 12000 Series 1-Port OC-48 STM-16 POS SDH ISE Line Card

Carefully slide the line card into the slot until the ejector levers make contact with the edges of the card 
cage, then stop when the ejector lever hooks catch the lip of the card cage. If they do not catch, try 
reinserting the line card until the ejector lever hooks are fully latched. (See 

Figure 11

.) 

When you install a line card, always use the ejector levers to ensure that the card is correctly aligned 
with the backplane connector, the card connector pins make contact with the backplane in the correct 
order, and the card is fully seated in the backplane. A card that is only partially seated in the backplane 
can cause the router to hang and subsequently crash.

Simultaneously pivot both ejector levers toward each other until they are perpendicular to the line card 
faceplate. This action firmly seats the card in the backplane.

Use a 3/16-inch flat-blade screwdriver to tighten the captive screw on each end of the line card faceplate 
to ensure proper EMI shielding and to prevent the line card from becoming partially dislodged from the 
backplane. 

To ensure adequate space for additional line cards, always tighten the captive installation screws on each 
newly installed line card before you insert any additional line cards. These screws also prevent accidental 
removal and provide proper grounding and EMI shielding for the router.

Install the cable-management bracket. 

Install the interface cables. 

 

The illustrations in this section show various line cards, but the line card cable-management bracket 
installation procedure is the same regardless of the specific line card.

When inserting a card, make

sure the ejector lever hooks

catch the lip of the card cage.
