Abstract: Apparatuses and methods are provided for locking an air-moving assembly within a chassis when in operational state. The apparatus includes a locking louver assembly having a louver(s) and locking mechanism. The louver(s) is disposed at an air inlet or outlet of the air-moving assembly, and pivots between operational and quiesced orientations, dependent on presence or absence, respectively, of airflow through the air-moving assembly. The locking mechanism includes a keying element(s) affixed to the louver(s) to pivot therewith, which includes an elongated key(s) oriented in a first direction when the louver(s) is in operational orientation, and a second direction when in quiesced orientation. A key-receiving element(s) is associated with the chassis and includes a key opening(s) which receives and accommodates movement of the elongated key(s) between the first and second directions, and prevents removal of the air-moving assembly from the chassis with the key(s) oriented in the first direction.

Abstract: Apparatuses and methods are provided for blocking removal of an air-moving assembly from a chassis when in operational state. The apparatus includes a protective louver assembly having a louver(s) and an interlock element(s). The louver(s) is disposed at an air inlet or an air outlet of the air-moving assembly, and pivots between an operational and a quiesced orientation, dependent on presence or absence, respectively, of airflow through the air-moving assembly. The interlock element(s) is associated with the louver(s) to pivot with the louver(s) between the operational orientation and the quiesced orientation. In the operational orientation, the interlock element(s) blocks, at least in part, access to at least one fastener securing the air-moving assembly within the chassis, and thereby prevents removal of the air-moving assembly from the chassis when in the operational state.

Abstract: Apparatuses and methods are provided for blocking removal of an air-moving assembly from a housing when in operational state. The apparatus includes a protective louver assembly having a louver(s) and an interlock element(s). The louver(s) is disposed at an air inlet or an air outlet of the air-moving assembly, and pivots between an operational and a quiesced orientation, dependent on presence or absence, respectively, of airflow through the air-moving assembly. The interlock element(s) is associated with the louver(s) to pivot with the louver(s) between the operational orientation and the quiesced orientation. In the operational orientation, the interlock element(s) blocks, at least in part, access to at least one fastener securing the air-moving assembly within the housing, and thereby prevents removal of the air-moving assembly from the chassis when in the operational state.

Abstract: Apparatuses and methods are provided for preventing removal of an air-moving assembly from a chassis when in operating state. The apparatus includes an interlock assembly having a slide element and one or more interlock elements. The slide element is slideably coupled to the air-moving assembly and resides in a first position when the air-moving assembly is in the operating state, and is slidable to a second position when the air-moving assembly is in a quiesced state. The slide element prevents removal of the air-moving assembly from the chassis in the first position, and allows removal of the air-moving assembly from the chassis in the second position. The interlock element(s) is associated with the slide element and prevents sliding of the slide element from the first position to the second position when the air-moving assembly is in the operating state.
