Set both edges of the RP or line card carrier into the card slot carrier alignment
Step 4
grooves on either side of the card cage.
Caution Do not allow the line card to rest partially inserted into the slots as this will
damage the EMI shielding on the RP or line card in the slot directly below.
Pivot the ejector levers away from each other; rotate each ejector lever outward
Step 5
away from the faceplate.
Grasp the edges of the metal card carrier with both hands to support and guide the
Step 6
RP or line card into the slot alignment grooves in the card cage.
One edge of the card carrier faceplate is lined with an EMI-preventive gasket
Caution
consisting of many raised, conductive contacts. Be careful not to damage the
gasket contacts, because a damaged card carrier gasket can result in reduced EMI
performance.
Use both thumbs to slide the card carrier into the RP or line card slot until the
Step 7
ejector levers make contact with the front of the card cage, then stop.
Grasp the two RP or line card ejector levers and pivot them toward the card
Step 8
faceplate until they are perpendicular to the faceplate; this action will seat the RP
or line card in the backplane connector.
Note
Tighten the captive screws on each side of the card faceplate to prevent the RP or
Step 9
line card from becoming partially dislodged from the backplane and to ensure
proper EMI shielding.
Note
Repeat Step 1 through Step 9 for any additional replacement RPs or line cards,
and then proceed to the next section.

The line card will not boot properly if not fully seated.
The line card captive screws must be tightened to meet EMI specification
standards.
