Described is a label cassette for mounting to the front side of an enclosure and for holding and displaying a label used to identify a configuration of that enclosure. The label cassette includes a transparent cover, a tray, and a hinge mechanism. The tray has a pair of guide rails for engaging respective guide structures on the enclosure to align the label cassette for attachment to the enclosure, a capture mechanism to secure the label cassette to the enclosure, and a label surface to hold a label. The hinge mechanism attaches the transparent cover to the tray and permits rotation about an axis parallel to the back edge of the transparent cover. Mounted to a ledge that extends from the front of the enclosure, the label cassette does not occupy vertical space or interfere with connectors, cables, or airflow vents on the front of the enclosure.

What is claimed is: 1. A label cassette for an electronics enclosure with guide structures on opposite sides of a cassette surface having an opening therein, the label cassette comprising: a transparent cover having a back edge; a tray having a base for providing a label surface for holding a label, the base being bounded on opposite sides by side shoulders, each side shoulder having a guide rail extending laterally along an exterior surface of that side shoulder, the base having an opening formed therein with a flexible capture mechanism disposed in the opening, the flexible capture mechanism having an unattached first end and a second end that is attached to the base, the unattached first end having a projection that extends out of the opening in the base, wherein as the guide rails slide through the guide structures of the electronics enclosure the cassette surface of the electronics enclosure encounters and urges the projection towards the opening in the base until the projection enters the opening in the cassette surface, whereupon the flexible capture mechanism returns to an unflexed position that secures the projection within the opening in the cassette surface; and a hinge mechanism rotatably attaching the transparent cover to the tray for rotation about an axis substantially parallel to the back edge of the transparent cover. 2. The label cassette of claim 1, wherein the transparent cover has two side edges, each side edge having a protrusion extending therefrom and wherein each side shoulder of the tray has an indentation for receiving one of the protrusions of the transparent cover when the label cassette is closed. 3. The label cassette of claim 1, wherein the hinge mechanism comprises: a hinge pin disposed parallel to the back edge of the transparent cover; and a hinge pin retainer disposed on a back edge of the tray. 4. The label cassette of claim 1, wherein the flexible capture mechanism comprises a flexible beam having a hooked end to enter and engage the opening in the cassette surface of the electronics enclosure. 5. The label cassette of claim 1, further comprising: at least one tab extending from a front edge of the tray; and at least one recessed region in a front edge of the transparent cover to accept the at least one tab when the label cassette is closed. 6. The label cassette of claim 1, wherein each side shoulder of the tray has a top portion and the transparent cover has an exterior-facing surface that lies flush with the top portion of each side shoulder when the transparent cover is in the closed position. 7. The label cassette of claim 1, wherein the tray has a raised front edge extending between the side shoulders of the tray, the raised front edge of the tray being lower in height than the side shoulders of the tray. 8. The label cassette of claim 7, wherein each side shoulder has a curved front portion and the transparent cover has a curved front portion that couples to the raised front edge of the tray when the transparent cover is in the closed position. 9. The label cassette of claim 8, wherein the curved front portion of the transparent cover lies flush with the curved front portions of the side shoulders of the tray when the transparent cover is in the closed position. 10. An electronics enclosure, comprising: a base; an electronics module supported by the base, the electronics module having a panel that is substantially perpendicular to the base; a label cassette holder comprising an external ledge extending from the base past the panel of the electronics module, the ledge having a cassette surface with an opening formed therein and having a guide structure disposed along one side of the cassette surface; and a label cassette having: a transparent cover having a back edge; a tray with a base for providing a label surface for holding a label, the base being bounded on opposite sides by side shoulders, one of the side shoulders having a guide rail extending laterally along an exterior surface of that side shoulder, the base having an opening formed therein with a flexible capture mechanism disposed in the opening, the flexible capture mechanism having an unattached first end and a second end that is attached to the base, the unattached first end having a projection that extends out of the opening in the base, wherein, as the guide rail slides through the guide structure, the cassette surface of the electronics enclosure encounters and urges the projection towards the opening in the base until the projection enters the opening in the cassette surface of the ledge, whereupon the flexible capture mechanism returns to an unflexed position that secures the projection within the opening in the cassette surface; and a hinge mechanism rotatably attaching the transparent cover to the tray for rotation about an axis substantially parallel to the back edge of the transparent cover. 11. The electronics enclosure of claim 10, wherein the transparent cover has two side edges each having a protrusion extending therefrom and wherein the tray has a pair of shoulders disposed at opposite ends of the label surface, each shoulder having an indentation configured to receive the protrusions in the side edges of the transparent cover when the label cassette is in a closed configuration. 12. The electronics enclosure of claim 10 wherein the tray is substantially parallel to the front ledge when secured thereto. 13. The electronics enclosure of claim 10, wherein the hinge mechanism comprises: a hinge pin disposed parallel to the back edge of the transparent cover; and a hinge pin retainer disposed on a back edge of the tray. 14. The electronics enclosure of claim 10, wherein the capture mechanism comprises a flexible beam having a hooked end to enter and engage the opening in the cassette surface of the ledge. 15. The electronics enclosure of claim 10, further comprising: at least one tab extending from a front edge of the tray; and at least one recessed region in a front edge of the transparent cover to accept the at least one tab when the label cassette is closed. 16. The electronic enclosure of claim 10, wherein each side shoulder of the tray has a top portion and the transparent cover has an exterior-facing surface that lies flush with the top portion of each side shoulder when the transparent cover is in the closed position. 17. The electronic enclosure of claim 10, wherein the tray has a raised front edge that is lower in height than the side shoulder of the tray. 18. The electronic enclosure of claim 17, wherein each side shoulder has a curved front portion and the transparent cover has a curved front portion that couples to the raised front edge of the tray when the transparent cover is in the closed position, the transparent cover lying flush with the curved front portion of each side shoulder of the tray when the transparent cover is in the closed position. 19. The electronic enclosure of claim 10, wherein the ledge is substantially perpendicular to the panel of the electronics module.
