An apparatus for aligning a bracket member of a circuit board assembly as the bracket member is positioned against and secured to an electronic chassis is provided. A circuit board assembly includes a circuit board operatively attached to a bracket member. The bracket member includes a first end, a second end, an outer surface and an inner surface. A gasket is longitudinally oriented along the outer surface of the bracket member. A first pin extends from the inner surface adjacent the first end, and a second pin extends from the inner surface adjacent the second end. An electronic chassis includes a top flange and a bottom flange. The top flange includes a top flange opening and the bottom flange includes a bottom flange opening. The first pin is aligned with and extends through the top flange opening and the second pin is aligned with and extends through the bottom flange opening to align the bracket member as the bracket member is positioned against and secured to the electronic chassis.

An apparatus for mounting a backplane circuit board to an electronic chassis is provided. An electronic chassis includes a first card guide assembly and a second card guide assembly. The first card guide assembly includes first and second guide pins. The first guide pin of the first card guide assembly is positioned adjacent a first end of the first card guide assembly and the second guide pin of the first card guide assembly is positioned adjacent a second end of the first card guide assembly. The second card guide assembly includes first and second guide pins. The first guide pin of the second card guide assembly is positioned adjacent a first end of the second card guide assembly and the second guide pin of the second card guide assembly is positioned adjacent a second end of the second card guide assembly. A backplane circuit board includes first and second openings to receive the first and second guide pins of the first card guide assembly and third and fourth openings to receive the first and second guide pins of the second card guide assembly. The third and fourth openings have a diameter less than a diameter of the first and second openings to allow a user to first position a bottom portion of the backplane circuit board against the second card guide assembly wherein the third and fourth openings receive the first and second guide pins of the second card guide assembly and second, to position a top portion of the backplane circuit board against the first card guide assembly wherein the first and second openings receive the first and second guide pins of the first card guide assembly to allow proper alignment of the backplane circuit board to the first and second card guide assemblies.

An apparatus for mounting a circuit board assembly to an electronic chassis is provided. A circuit board assembly includes a circuit board operatively attached to a bracket member having a first end and a second end. A first connector member is rotatably attached to the first end, and a second connector member is rotatably attached to the second end. The first connector member includes a first hook portion and a first handle portion. The second connector member includes a second hook portion and a second handle portion. The first and second hook portions each include a first surface and a second surface oriented at an angle to the first surface. The first surface of the first hook portion contacts with a first spring and the first surface of the second hook portion contacts with a second spring to orient the first and second connectors in an insertion position. The second surface of the first hook portion contacts with the first spring and the second surface of the second hook portion contacts with the second spring to orient the first and second connector members in an intermediate position and a locked position.
