Daughter card assembly (106) includes a circuit board (120) having a leading edge (131) and a trailing edge (132) and leading and trailing connectors (122, 124) mounted to the circuit board via the leading edge and the trailing edge. The leading and trailing connectors have mating ends (127, 128) that face in different directions along a board plane (160). The daughter card assembly also includes a support wall (130) that is coupled to the circuit board and extends orthogonal to the circuit board. The support wall has a wall opening (370) therethrough. The trailing connector is positioned on the circuit board such that the mating end substantially aligns with the wall opening. The daughter card assembly also includes a retention shroud (140) that projects from an exterior surface of the support wall. The retention shroud defines a shroud passage (306) that aligns with the wall opening. The shroud and wall openings form a receiving passage for receiving at least one of the trailing connector or a corresponding cable connector that mates with the trailing connector.
