An injection/ejection mechanism is provided for mounting and dismounting of a unit in a chassis. The mechanism includes a drive screw that cooperates with a threaded barrel, the threaded barrel being rotatable for engagement and disengagement with at least one chassis component. The drive screw can be rotated in a first rotational direction to urge the threaded barrel in a first longitudinal direction against at least one chassis component for mounting of the unit and can be rotated in an opposite rotational direction to urge the threaded barrel in an opposite longitudinal direction against at least one chassis component for dismounting of the unit.

What is claimed is: 1. An injection/ejection mechanism for mounting and dismounting of a unit to a chassis, the mechanism comprising a unit having a drive screw that cooperates with a threaded barrel, the threaded barrel being rotatable for engagement and disengagement with at least one component of a chassis and the drive screw being rotatable in a first rotational direction to urge the threaded barrel in a first longitudinal direction against the at least one component of the chassis for mounting of the unit and being rotatable in an opposite rotational direction to urge the threaded barrel in an opposite longitudinal direction against the at least one component of the chassis for dismounting of the unit; wherein the unit includes a set of connectors that connect to corresponding connectors that are coupled to the chassis; wherein rotation of the drive screw in the first rotational direction is operable to urge the threaded barrel in an outward direction against the at least one component of the chassis to draw in the unit with respect to the chassis, causing the connectors for the unit to connect to the corresponding connectors that are coupled to the chassis. 2. The mechanism of claim 1, wherein rotation of the drive screw in the opposite rotational direction is operable to urge the threaded barrel in an inward direction against the at least one component of the chassis to push out the unit with respect to the chassis, causing the connectors for the unit to disconnect from the corresponding connectors that are coupled to the chassis. 3. The mechanism of claim 1, wherein a first said component of the chassis is a first wall and a second said component of the chassis is a second wall, rotation of the drive screw in the first rotational direction being operable to urge the threaded barrel against the first wall to draw in the unit with respect to the chassis and rotation of the drive screw in the opposite rotational direction is operable to urge the threaded barrel against the second wall to push out the unit with respect to the chassis. 4. The mechanism of claim 3, wherein the first wall is provided with a key-shaped hole configured to receive the threaded barrel in a first orientation of the threaded barrel, and to cause the threaded barrel to engage the first wall in a second orientation after rotation of the threaded barrel. 5. The mechanism of claim 1, comprising a lever coupled to the threaded barrel to cause rotation thereof of the threaded barrel. 6. The mechanism of claim 5, comprising a guide arranged to cause rotational movement of the threaded barrel on rotational movement of the lever and to cause linear movement of the threaded barrel with respect to the level on rotation of the drive screw. 7. The mechanism of claim 6, wherein the guide comprises at least one guide member configured to rotate with the lever and slideably mounted with respect to the threaded barrel, rotation of the lever being operable to cause the threaded barrel to rotate with the lever and the guide, and rotation of the drive screw being operable to cause the threaded barrel to slide along the guide. 8. The mechanism of claim 6, wherein the guide comprises at least one guide member configured to rotate with the threaded barrel and slideably mounted with respect to the lever, rotation of the lever being operable to cause the threaded barrel to rotate with the lever and the guide, and rotation of the drive screw being operable to cause the guide to slide with respect to the lever. 9. A field replaceable unit comprising at least one injection/ejection mechanism for mounting and dismounting of the unit in a chassis, the at least one mechanism comprising a drive screw that cooperates with a threaded barrel, the threaded barrel being rotatable for engagement and disengagement with at least one chassis component of a chassis and the drive screw being rotatable in a first rotational direction to urge the threaded barrel in a first longitudinal direction against the at least one component of the chassis for mounting of the unit and being rotatable in an opposite rotational direction to urge the threaded barrel in an opposite longitudinal direction against the at least one component of the chassis for dismounting of the unit; wherein the unit includes a set of connectors that connect to corresponding connectors that are coupled to the chassis; wherein rotation of the drive screw in the first rotational direction is operable to urge the threaded barrel in an outward direction against the at least one component of the chassis to draw in the unit with respect to the chassis, causing the connectors for the unit to connect to the corresponding connectors that are coupled to the chassis. 10. The field replaceable unit of claim 9, wherein the at least one injection/ejection mechanism includes a first mechanism and a second mechanism, the first mechanism being operable to cooperate with a chassis component at a first side of a chassis and the second mechanism being operable to cooperate with a chassis component at a second side of a chassis. 11. A chassis comprising at least one location for receiving a field replaceable unit that comprises at least one injection/ejection mechanism for mounting and dismounting of the unit in the chassis, wherein the at least one mechanism comprises a drive screw that cooperates with a threaded barrel, the threaded barrel being rotatable for engagement and disengagement with at least one component of the chassis and the drive screw being rotatable in a first rotational direction to urge the threaded barrel in a first longitudinal direction against the at least one component of the chassis for mounting of the unit and being rotatable in an opposite rotational direction to urge the threaded barrel in an opposite longitudinal direction against the at least one component of the chassis for dismounting of the unit, wherein the at least one location includes the at least one component of the chassis; wherein the unit includes a set of connectors that connect to corresponding connectors that are coupled to the chassis; wherein rotation of the drive screw in the first rotational direction is operable to urge the threaded barrel in an outward direction against the at least one component of the chassis to draw in the unit with respect to the chassis, causing the connectors for the unit to connect to the corresponding connectors that are coupled to the chassis. 12. The chassis of claim 11, wherein a first component of the chassis is a first wall and a second component of the chassis is a second wall, rotation of the drive screw in the first rotational direction being operable to urge the threaded barrel against the first wall to draw in the unit with respect to the chassis and rotation of the drive screw in the opposite rotational direction is operable to urge the threaded barrel against the second wall to push out the unit with respect to the chassis. 13. The chassis of claim 12, wherein the first wall is provided with a key-shaped hole configured to receive the threaded barrel in a first orientation of the threaded barrel, and to cause the threaded barrel to engage the first wall in a second orientation after rotation of the threaded barrel. 14. The chassis of claim 11, wherein the at least one location comprises a first said chassis component at a first side of the chassis and a second said chassis component at a second side of the chassis. 15. The chassis of claim 11, wherein said at least one location comprises a field replaceable unit received therein. 16. The mechanism of claim 1, wherein the set of connectors for the unit includes electrical connectors. 17. The mechanism of claim 1, wherein prior to rotating the drive screw to mount the unit, the connectors for the unit are not connected to the corresponding connectors that are coupled to chassis.
