A card retention system comprises a chassis and a bracket provided to
secure to the chassis by a first retention member. The first retention
member is selectively oriented in one of a first position and a second
position. The first position limits lateral movement of the bracket. The
second position limits lateral and vertical movement of the bracket. A
second retention member may also be provided on the chassis to
resiliently engage the bracket to limit vertical movement of the bracket
on the chassis.
