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.
Release the air deflector latch (turn the latch clockwise) and lower the air deflector down

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.
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.
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.
Carefully slide the line card carrier into the slot until the ejector levers make contact with
the front of the card cage, then stop.
