5.
Slide the card into the Acme Packet 4600. The physical interface card circuit
board slides into the guide rails in the NIU bay of the system chassis.
6.
Continue sliding the card into the chassis until the ejection levers meet the chassis
and start to fold inward as the NIU is inserted into the chassis.
7.
Fold both ejection levers inward toward the card to complete the NIU connection to
the motherboard. Pushing the ejection levers inward draws the physical interface
card toward the system chassis and completes the connection.
Ensure pressure is applied to the ends of the ejector (not the sliding section) when
seating the NIU/TCU.
8.
Verify the lever catch is fully engaged with the bezel.
