초록 ▼

A cam handle assembly for use with a modular information handling system components includes a latch with first protrusion and a second protrusion. The first protrusion is sloped such that when the sloped portion of the first protrusion contacts a portion of a rack or chassis, the latch is urged to a recessed position that will allow the cam handle to move between its closed and open position. The second protrusion on the latch is formed to engage an interface aperture that is formed in the cam handle. The interaction between the latch protrusions, the cam handle and the rack encourage proper operation of the cam handle to install an information handling system component within a rack.

What is claimed is: 1. An information handling system comprising: a modular information handling system component; a cam handle having an interface aperture formed therein, the cam handle coupled to the modular information handling system component and rotatable between a closed position and an open position; a latch having a first protrusion and a second protrusion, the latch movable between an engagement position and a recessed position; the first protrusion having a sloped portion operable to urge the latch to the recessed position when the first protrusion interacts with a portion of an information handling system rack; and the second protrusion formed to engage the cam handle interface aperture. 2. An information handling system according to claim 1 wherein the latch comprises a leaf spring. 3. An information handling system according to claim 1 wherein the modular information handling system component comprises a power supply. 4. An information handling system according to claim 1 wherein the modular information handling system component comprises a modular fan assembly. 5. An information handling system according to claim 1 wherein the recessed position of the latch allows the cam handle to rotate between the open position and the closed position. 6. An information handling system according to claim 1 wherein the second protrusion comprises a sloped portion formed such that interaction with a portion of the interface aperture urges the latch to the recessed position, thereby allowing the cam handle to rotate from the closed position to the open position. 7. An information handling system according to claim 1 wherein: the interface aperture comprises a notch formed therein; and the second protrusion having a lip extending therefrom and sized to fit within the notch. 8. An information handling system according to claim 7 further comprising the notch operable to prevent movement of the latch from the engagement position to the recessed position while the cam handle is in the closed position. 9. An information handling system according to claim 1 wherein: the cam handle further comprises a first arm and a second arm extending therefrom; the first arm extending from an edge of the modular information handling system component when the cam handle is in the closed position, thereby preventing complete insertion of the modular component into a rack system; the second arm offset from the first arm and formed such that a portion of second arm extends from the edge of the modular information handling system when the latch is positioned in the open position, such that the modular information handling component is selectively positioned with respect to the rack system. 10. An information handling system according to claim 9 wherein the first arm is positioned with respect to the second arm such that, after the modular component is positioned in the selected position, movement of the cam handle from the open position to the closed position causes the first arm to contact a portion of the rack, thereby urging the modular information handling system into a fully inserted position within the rack. 11. A cam assembly for use with an information handling system component comprising: a cam handle having an interface aperture formed therein, the cam handle formed to couple to a portion of an information handling system component such that the cam handle is rotatable between a closed position and an open position; a latch having a first protrusion and a second protrusion, the latch movable between an engagement position and a recessed position; the first protrusion having a sloped portion operable to urge the latch to the recessed position when the first protrusion interacts with a portion of an information handling system rack; and the second protrusion formed to engage the cam handle interface aperture. 12. A cam assembly according to claim 11 wherein the latch comprises a leaf spring. 13. A cam assembly according to claim 11 wherein the recessed position of the latch allows the cam handle to rotate between the open position and the closed position. 14. A cam assembly according to claim 11 wherein the second protrusion comprises a sloped portion formed such that interaction with a portion of the interface aperture urges the latch to the recessed position, thereby allowing the cam handle to rotate from the closed position to the open position. 15. A cam assembly according to claim 11 wherein: the interface aperture comprises a notch formed therein; and the second protrusion having a lip extending therefrom and sized to fit within the notch. 16. A cam assembly according to claim 15 further comprising the notch operable to prevent movement of the latch from the engagement position to the recessed position while the cam handle is in the closed position. 17. A method for installing an information handling system component within a rack system comprising: rotatably coupling a cam handle to a modular information handling system component such that the cam handle rotates between a closed position and an open position; forming an interface aperture in the cam handle; and providing a latch having a first protrusion and a second protrusion, the latch movable between an engagement position and a recessed position, the first protrusion having a sloped portion operable to urge the latch to the recessed position when the first protrusion interacts with a portion of an information handling system rack and the second protrusion formed to engage the cam handle interface aperture. 18. A method according to claim 17 wherein providing the latch comprises providing a leaf spring. 19. A method according to claim 17 further comprising moving the latch to the recessed position thereby allowing the cam handle to rotate between the open position and the closed position. 20. A method according to claim 17 wherein the second protrusion comprises a sloped portion formed such that interaction with a portion of the interface aperture urges the latch to the recessed position, thereby allowing the cam handle to rotate from the closed position to the open position.
