<p>A mounting system for facilitating removal and replacement of circuit cards in a card cage includes a carrier (100) having a generally planar shape and having a plurality of location holes (102) therethrough. A first circuit card edge support (108) is disposed at the bottom edge of the carrier (100). A first anchor assembly (502) includes a first circuit card locator (300) and a fastener system (400). The first circuit card locator (300) is removably mounted to the carrier (100) by the fastener system (400), a portion of which passes through one of the location holes (102) in the carrier (100). The first circuit card locator (300) is equipped with a support ledge (302) and a hold-down tab (304) for engaging opposite sides of a circuit card while the first circuit card edge support (108) engages an edge of the circuit card. A second anchor assembly (506) includes a post (310) oriented generally perpendicular to the plane of the carrier (100) and passes at least partially through a tooling hole (508) in the circuit card. A second circuit card edge support (108) may also be disposed at the bottom edge of the carrier (100). Alignment tabs (110) are disposed at the bottom edge of the carrier (100) and pass partially through a clearance slot (808) in the backplane (800). Guide blocks (700) on the backplane (800) better position the alignment tabs (110). Detent bumps (710) on the guide blocks (700) engage detent holes (112) on the alignment tabs (110), indicating when the carrier (100) is correctly positioned. <IMAGE></p> |
