Removing and Replacing a Card Cage Assembly
Step 4 Grasp the card carrier edge with one hand and place your other hand under the carrier to
support and guide it into a matching color-coded slot. Slide the card halfway into the
lower card cage slot. Avoid touching the card circuitry or any connectors.
Note When you install a clock and scheduler card or a switch fabric card in the lower
card cage make sure that you keep the card centered in the slot by applying even pressure
to both sides of the card carrier as you slide it into the slot.
Step 5 Pivot the two card ejector levers out ninety degrees away from the sides of the card carrier.
Step 6 Continue sliding the card into the slot until the card ejector levers engage the edges of the
lower card cage slot and both ejector levers begin to pivot.
Note Both types of cards have guide pins that make initial contact with the backplane
connector. After the guide pins make contact, continue pushing on the card carrier until
the card ejector levers start pivoting forward. Then use the card ejector levers to fully
insert the card in the backplane connector.
Step 7 Grasp both card ejector levers and pivot them toward the sides of the card cage until they
are parallel to the card carrier edge, to seat the card in the backplane connector. Press on
the ejector levers until they snap into the card carrier.
Step 8 Release the air deflector latch (turn the latch clockwise) and lower the air deflector down
to its stops.
Repeat Step 3 through Step 7 for the rest of the cards in the lower card cage.
Step 9 Pivot the air filter tray up so that it is flush with the front of the lower card cage and tighten
the two captive screws.
Replacing the Cards in the Upper Card Cage
This section provides the procedures for replacing the line cards, RP, and alarm card in the upper
card cage.
Replacing a Line Card in the Upper Card Cage
Perform the following steps to replace a line card in the upper card cage:
Step 1 Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets
located on the front edges of the upper card cage or to bare metal on the frame.
Step 2 Select a line card from the antistatic card mat. Check your list of occupied upper card cage
slots to determine which slot the line card goes in. Grasp the front edge of the metal card
carrier with one hand and place your other hand under the carrier to support and guide it
into the upper card cage slot.
Step 3 Carefully slide the line card carrier into the slot until the ejector levers make contact with
the front of the card cage, then stop.
