Card Actuation Lever for Single Channel Fiber Optic Cards

      Disclosed is a mechanism that provides controlled insertion and
extraction of a fiber-optic channel card into and out of a hot
pluggable card on board package.  The mechanism provides for a
positive retention of the card upon installation and is operable
without the need to remove the protective or wrap plug from the
optical module.

      In Fig. 1, the card 1, fiber-optic module 2 with protective
plug 3, and retention plate 4 are clamped together with four screws.
The lever 6 is riveted 7 to the retention plate, thus forming a pivot
point.  Upon actuation, the lever 6 rotates about the riveted pivot
point 7 causing the forked end 8, which mates with a corresponding
feature 9 (Fig. 2) in the card cage, to drive the card in or out of
the package and connector.

      Fig. 3 illustrates the path of the lever around the protective
plug during actuation.  The tab 10 on the lever engages with the
opening 11, forming a positive lock upon card installation.
