DETAILED DESCRIPTION

[0018] Preferred embodiments and their advantages are best understood by reference to FIGS. 1A through 4B, wherein like numbers are used to indicate like and corresponding parts.

[0019] For the purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, entertainment, or other purposes. For example, an information handling system may be a personal computer, a PDA, a consumer electronic device, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include memory, one or more processing resources such as a central processing unit (CPU) or hardware or software control logic. Additional components or the information handling system may include one or more storage devices, one or more communications ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more buses operable to transmit communication between the various hardware components.

[0020] For the purposes of this disclosure, information handling resources may broadly refer to any component system, device or apparatus of an information handling system, including without limitation processors, buses, memories, input-output devices and/or interfaces, storage resources, network interfaces, motherboards, integrated circuit packages; electro-mechanical devices (e.g., air movers), displays, and power supplies.

[0021] FIGS. 1A and 1B illustrate an example 1U air mover 100, in accordance with embodiments of the present disclosure. FIG. 1A illustrates air mover 100 in a first configuration, while FIG. 1B illustrates air mover 100 in a second configuration.

[0022] As shown in FIGS. 1A and 1B, air mover 100 may include a body 102, a cable 104 of wires electrically coupled to and extending from body 102, and air mover holders 106 mechanically coupled to each end of body 102.

[0023] Body 102 may include the main components of air mover 100, including an impeller for moving air, a motor for driving the impeller, electric components, electronic components, and other components, and a housing for housing the various components.

[0024] Cable 104 may comprise a plurality of electrically-conductive wires for carrying electrical energy for powering air mover 100, for carrying electronic signals for controlling operation of air mover 100, and/or for carrying electronic signals representative of telemetry information of air mover 100. One end of cable 104 may terminate into body 102, while the other end of cable 104 may terminate into a connector 112.

[0025] Air mover holders 106 may be sized and shaped to conform to features of air mover 100 and a chassis of an information handling system chassis to guide an air mover 100 into such information handling system chassis. As shown in FIGS. 1A and 1B, each air mover holder 106 may include a cable management feature 108 formed therein that may serve as a guiding and/or retention feature for cable 104. For example, in the first configuration, cable management feature 108 of one air mover holder 106 may be used to guide and retain cable 104 in a particular position, while in the second configuration, cable management feature 108 of the other air mover holder 106 may be used to guide and retain cable 104 in a particular position. Accordingly, a wire exit direction for air mover 100 may be easily configurable based on the orientation of air mover 100 within a chassis and location of a corresponding electrical connector to which connector 112 is to be coupled.

[0026] Also as depicted in FIG. 1A, one or both of air mover holders 106 may include keying features 110. Each keying feature 110 may include an interference feature configured to mechanically interact with a corresponding interference feature of an information handling system chassis when an attempt is made to insert air mover 100 in an orientation different than that of the proper airflow direction of such air mover 100.

[0027] FIGS. 2A and 2B illustrate an example 2U air mover, in accordance with embodiments of the present disclosure. FIG. 2A illustrates a front of air mover 200, while FIG. 2B illustrates a rear of air mover 200.

[0028] As shown in FIGS. 2A and 2B, air mover 200 may include a body 202 and an air mover holder 206 mechanically coupled to body 202.

[0029] Body 202 may include the main components of air mover 200, including an impeller for moving air, a motor for driving the impeller, electric components, electronic components, and other components, and a housing for housing the various components.

[0030] Air mover holder 206 may be sized and shaped to conform to features of air mover 200 and a chassis of an information handling system chassis to guide an air mover 200 into such information handling system chassis. As shown in FIGS. 2A and 2B, air mover holder 206 may include a cable channel 204 and cable management features 208 at each end of cable channel 204. Air mover holder 206 may be mechanically coupled to body 202 such that a cable (which may be identical or similar to cable 104, described above) may extend from body 202 into channel 204. Channel 204 may thus serve as a guiding feature for such cable. Likewise, each cable management feature 208 may serve as a guiding and/or retention feature for a cable of air mover 200. For example, in a first configuration, a first cable management feature 208 may be used to guide and retain a cable in a particular position, while in a second configuration, the other cable management feature 208 may be used to guide and retain the cable in a particular position. Accordingly, a wire exit direction for air mover 200 may be easily configurable based on the orientation of air mover 200 within a chassis and location of a corresponding electrical connector to which a connector of a cable is to be coupled.

[0031] Also as demonstrated in FIGS. 2A and 2B, the combination of body 202 and air mover holder 206 may create one or more keying features 210. For example, as shown in FIG. 2A, an offset between an edge of body 202 and air mover holder 206 may create a keying feature 210 such as a void or channel on one the front side of air mover 200 shown in FIG. 2A, while a similar feature is not present on the back side of air mover 200 as shown in FIG. 2B, and instead, an interfering feature 214, such as a corner of air mover holder 206, may be present. Accordingly, when air mover 200 is placed in a proper airflow orientation in a chassis, keying feature 210 may allow passage of air mover 200 by an interfering feature of a chassis, while when air mover 200 is placed in an improper airflow orientation in the chassis, keying feature 214 may interact with a corresponding interfering feature of the chassis to prevent full insertion of air mover 200 into such chassis.

[0032] FIG. 3A illustrates a front view of an example air mover gantry 300 with an air mover 100A properly inserted into air mover gantry 300, in accordance with embodiments of the present disclosure. FIG. 3B illustrates a rear view of example air mover gantry 300 with air mover 100B improperly inserted into air mover gantry 300, in accordance with embodiments of the present disclosure.

[0033] Air mover gantry 300 may include a portion of an information handling system chassis configured to receive and house air movers 100. Air mover gantry 300 may be positioned within a chassis and/or otherwise configured with appropriate mechanical features based on whether air mover gantry 300 will reside in a server in a hot-aisle configuration or a cold-aisle configuration. Depending on its configuration in either a hot-aisle configuration or a cold-aisle configuration, air mover gantry 300 may include interference features 302 that may interact with keying features 110 of air mover holders 106 to ensure proper insertion of air movers 100 in the proper airflow direction of the configuration of air mover gantry 300. For example, as shown in FIG. 3A, because air mover 100A is being inserted properly into air mover gantry 300, air mover 100A may be fully inserted in air mover gantry 300 due to air mover 100A being inserted in its proper orientation relative to air mover gantry 300. On the other hand, as shown in FIG. 3B, keying features 110 of air mover holders 106 of air mover 100B may mechanically interact with interference features 302, thus preventing full insertion of air mover 100B in the improper orientation with respect to air mover gantry 300.

[0034] FIG. 4A illustrates a top view of an example air mover gantry 400A and air mover 200 in a hot-aisle configuration, in accordance with embodiments of the present disclosure. In such configuration, air mover gantry 400A may have features unique to its hot-aisle configuration, for example configuration indicator 402A and an interference feature 404A extending from configuration indicator 402A. Due to lack of mechanical interference between keying feature 210 and interference feature 404A, air mover 200 may be fully inserted into air mover gantry 400A in the orientation shown in FIG. 4A.

[0035] FIG. 4B illustrates a top view of an example air mover gantry 400B and air mover 200 in a cold-aisle configuration, in accordance with embodiments of the present disclosure. In such configuration, air mover gantry 400B may have features unique to its cold-aisle configuration, for example configuration indicator 402B and an interference feature 404B extending from a portion of air mover gantry 400B. Due to lack of mechanical interference between keying feature 210 and interference feature 404B, air mover 200 may be fully inserted into air mover gantry 400B in the orientation shown in FIG. 4B.
