AMC CARRIER FACEPLATES
A faceplate for AMC carriers is fabricated from extruded aluminum using a combination of extruded cross-sectional features and machined features to achieve the structural and functional characteristics of an AdvancedTCA faceplate. The extruded aluminum faceplate significantly improves on sheet-metal alternatives while substantially conforming to the AdvancedTCA specification.

the extruded material having at least one machined feature adapted for assembly into the AMC carrier.
14 . The extruded faceplate of claim 13 wherein the tapered edge includes at least one tapered side to facilitate insertion of the AMC carrier into a chassis.
15 . The extruded faceplate of claim 13 wherein the tapered edge includes a taper to facilitate attachment to a plurality of offset fingers extending from a sheet metal carrier cover.
16 . The extruded faceplate of claim 15 further comprising the sheet metal carrier cover, the sheet metal carrier cover attached to the extruded faceplate with at least two of the offset fingers on each side of the tapered edge.
17 . An extruded faceplate comprising:
an extruded material having a length sized for use as a faceplate for an AMC carrier, the extruded material having a front side that forms an outside surface of the AMC carrier and a rear side that forms an interior surface of the AMC carrier;
the extruded material having a cross-sectional shape including at least one profile feature adapted for assembly into the AMC carrier; and
the extruded material having an opening machined therein extending from the front surface to the rear surface, the opening shaped and sized to receive an AMC module and the opening including a beveled edge oriented to guide insertion of the AMC module into the opening through the front surface.
18 . The extruded faceplate of claim 17 further comprising at least one notch formed in an edge extending rearward from the rear surface, the notch providing two opposing lateral supports for a card guide positioned behind the extruded faceplate.
19 . The extruded faceplate of claim 17 further comprising an attachment leg extruded into the cross-sectional shape and extending rearward from the rear surface, the attachment leg adapted to secure a card guide strut in a position to support a carrier cover.
20 . A card carrier comprising:
a faceplate formed of an extruded material having a length sized for use in an AMC carrier, the faceplate having a front side that forms an outside surface of the AMC carrier and a rear side that forms an interior surface of the AMC carrier, the front side and the rear side connected by a top edge and a bottom edge to form a cross-sectional shape including at least one profile feature adapted for assembly into the AMC carrier, the extruded material further including at least one machined feature adapted for assembly into the AMC carrier, the faceplate forming a front of the card carrier;
a first carrier cover formed of sheet metal and removably and replaceably attached to the top edge of the faceplate, the first carrier cover forming a top of the card carrier;
