Abstract
Devices, systems, and methods for managing chassis of data processing systems are disclosed. The chassis may be managed by reversibly attaching them to structural members such as rails. When so attached, the chassis may be fixedly held in a position. To facilitate access to an interior of the chassis, the chassis may be detached from the structural member and moved to a maintenance position. To detach the chassis from the structural member, the chassis may include a latch assembly. The latch assembly may include features to inform and remind technicians or other persons of the existence, or lack thereof, of various lines connecting the chassis, and components positioned in the chassis, to other components.
Claims20
A data processing system, comprising:
- a chassis to house hardware components, the hardware components comprising a cooling system;
- an ear of the chassis, the ear of the chassis comprising:
- a reserved area, and
- a latch area;
- a latch assembly positioned with the latch area and fixedly attached to the chassis, comprising:
- a latch comprising:
- a first portion mechanically coupled to translate between a first position and a second position with respect to a second portion of the latch;
- the second portion of the latch, the second portion comprising an indicator that is adapted to indicate an attachment state of the cooling system to an external component outside of the chassis via one or more structural elements, the attachment state indicating whether the cooling system is physically connected to or physically detached from the external component via the one or more structural elements;
- a pivot mechanically coupled to the second portion, the pivot being adapted facilitate rotation of the first portion and the second portion between the second position and a third position;
- and
- an interference portion adapted to:
- prevent the latch from rotating while the first portion is in the first position;
- and
- allow the latch to rotate while the first portion is in the second position.

A chassis, comprising:
- an ear, comprising:
- a reserved area, and
- a latch area;
- and
- a latch assembly positioned with the latch area and fixedly attached to the chassis, the chassis being configured to house hardware components that comprise a cooling system, and the latch assembly comprises:
- a latch comprising:
- a first portion mechanically coupled to translate between a first position and a second position with respect to a second portion of the latch;
- the second portion of the latch, the second portion comprising an indicator that is adapted to indicate an attachment state of the cooling system to an external component outside of the chassis via one or more structural elements, the attachment state indicating whether the cooling system is physically connected to or physically detached from the external component via the one or more structural elements;
- a pivot mechanically coupled to the second portion, the pivot being adapted facilitate rotation of the first portion and the second portion between the second position and a third position;
- and
- an interference portion adapted to:
- prevent the latch from rotating while the first portion is in the first position;
- and
- allow the latch to rotate while the first portion is in the second position.
11 more elements
A latch assembly, comprising:
- a latch, wherein the latch assembly is fixedly attached to a chassis of a data processing system, the chassis being configured to house hardware components that comprise a cooling system, the chassis further comprising an ear that comprises a reserved area and a latch area, the latch assembly being fixedly attached to the chassis within the latch area,
- and the latch comprises:
- a first portion mechanically coupled to translate between a first position and a second position with respect to a second portion of the latch;
- the second portion of the latch, the second portion comprising an indicator that is adapted to indicate an attachment state of the cooling system to an external component outside of the chassis via one or more structural elements, the attachment state indicating whether the cooling system is physically connected to or physically detached from the external component via the one or more structural elements;
- a pivot mechanically coupled to the second portion, the pivot being adapted facilitate rotation of the first portion and the second portion between the second position and a third position;
- and
- an interference portion adapted to:
- prevent the latch from rotating while the first portion is in the first position;
- and
- allow the latch to rotate while the first portion is in the second position.
