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 modular
