Abstract

Various embodiments of an electronic system and method for removing a power module from an electronic system are provided. The electronic system includes a power module that supplies power to a load and is movable along an axis from an enabling position to a disconnected position. The electronic system also includes a release control that restricts the movement of the power module along the axis when the power module is moved beyond a disabling position located between the enabling position and the disconnected position.

Claims

1. An electronic system comprising:

a first power module that supplies power to a load external to the first power module through an output voltage connector in an enabling position, the first power module supported by a chassis through a front panel of the chassis and is movable extractable from the chassis along an axis from the enabling position in which a signal connector and the output voltage connector are connected to a disconnected position in which the first power module is disconnected from the load without removal of the front panel from the chassis, the chassis being external to the first power module; and

a release control that restricts the movement of the first power module along the axis after the first power module is moved past a disabling position in which the first power module is triggered by disconnection of the signal connector to reduce the power supplied to the load while the first power module remains connected to the load through the output voltage connector when restricted by the release control, the disabling position located between the enabling position and the disconnected position in which the signal connector and the output voltage connector are disconnected, wherein the release control does not restrict the movement of the first power module from the enabling position to the disabling position, the release control comprising a protrusion that contacts the chassis causing the first power module to stop when the first power module is moved along the axis to a position between the disabling position and the disconnected position.

2. The electronic system of claim 1, further comprising:

a second power module that supplies power to the load and is in electrical communication with the first power module; and

wherein the second power module is configured to increase power to the load when the first power module is moved to the disabling position.

3. The electronic system of claim 1, wherein:

the first power module comprises the signal connector and the output voltage connector, the length of the signal connector being shorter than the length of the output voltage connector; and

the release control restricts the movement of the first power module along the axis when the signal connector is disconnected and the output voltage connector is connected to the load.

4. The electronic system of claim 1, wherein the power output provided by the first power module is less than about 90% or less of an operating voltage of the electronic system when the first power module is disconnected from the load.

5. The electronic system of claim 1, wherein the release control further comprises a spring configured to urge the protrusion of the release control toward the chassis.

6. An electronic system comprising:

a first power module that supplies power to a load external to the first power module through an output voltage connector in an enabling position, the first power module supported by a chassis through a front panel of the chassis and is movable extractable from the chassis along an axis from the enabling position in which a signal connector and the output voltage connector are connected to a disconnected position in which the first power module is disconnected from the load without removal of the front panel from the chassis; and

a release control that restricts the movement of the first power module along the axis after the first power module is moved past a disabling position in which the first power module is triggered by disconnection of the signal connector to reduce the power supplied to the load while the first power module remains connected to the load through the output voltage connector when restricted by the release control, the disabling position located between the enabling position and the disconnected position in which the signal connector and the output voltage connector are disconnected, wherein the release control does not restrict the movement of the first power module from the enabling position to the disabling position, and the release control comprises a protrusion that contacts the first power module causing it to stop when the first power module is moved along the axis to a position between the disabling position and the disconnected position.

7. The electronic system of claim 6, wherein the release control further comprises a recess in the power module configured to contact the protrusion at the position between the disabling position and the disconnected position.

8. An electronic system comprising:

a first power module that supplies power to a load external to the first power module through an output voltage connector in an enabling position, the first power module supported by a chassis through a front panel of the chassis and is movable extractable from the chassis along an axis from the enabling position in which a signal connector and the output voltage connector are connected to a disconnected position in which the first power module is disconnected from the load without removal of the front panel from the chassis; and

a release control that restricts the movement of the first power module along the axis after the first power module is moved past a disabling position in which the first power module is triggered by disconnection of the signal connector to reduce the power supplied to the load while the first power module remains connected to the load through the output voltage connector when restricted by the release control, the disabling position located between the enabling position and the disconnected position in which the signal connector and the output voltage connector are disconnected, wherein the release control does not restrict the movement of the first power module from the enabling position to the disabling position, and the release control comprises a rack and a pinion that come into contact with one another after the first power module is extracted past the disabling position causing the first power module to decelerate when it is moved along the axis between the disabling position and the disconnected position.

9. An electronic system comprising:

a first power module that supplies power to a load external to the first power module through an output voltage connector in an enabling position, the first power module supported by a chassis through a front panel of the chassis and is movable extractable from the chassis along an axis from the enabling position in which a signal connector and the output voltage connector are connected to a disconnected position in which the first power module is disconnected from the load without removal of the front panel from the chassis;

a release control that restricts the movement of the first power module along the axis after the first power module is moved past a disabling position in which the first power module is triggered by disconnection of the signal connector to reduce the power supplied to the load while the first power module remains connected to the load through the output voltage connector when restricted by the release control, the disabling position located between the enabling position and the disconnected position in which the signal connector and the output voltage connector are disconnected, wherein the release control does not restrict the movement of the first power module from the enabling position to the disabling position; and

a clinch that prevents disengaging a release of the release control power module without restriction of the movement of the first power module, wherein the release control restricts movement of the first power module along the axis by causing the first power module to stop.
