A connector system includes a first connector configured to be electrically connected to a predetermined device required for air discharge and to introduce air discharged from the predetermined device into the first connector, a first connection line surrounding a first cable electrically connected to the first connector, one side of the first connection line being connected to the first connector, and a second connector connected to an opposite side of the first connection line and electrically connected to the first cable, wherein the first connector, the first connection line, and the second connector are configured to communicate with each other such that the air introduced into the first connector is discharged through the second connector after passing through the first connection line.

An apparatus (1) comprising hardware equipment (3) having hardware components (10) enclosed by a chassis (2) having a front side (2A) and a rear side (2B), and auxiliary equipment (5) movable within the chassis (2) along at least one transportation rail (7) with a non-linear trajectory extending in horizontal plane between a first position at the front side (2A) of the chassis (2) and a second position behind the hardware equipment (3) at the rear side (2B) of the chassis (2), wherein a part of the hardware components (10) is at least temporarily removable from the chassis (2) or movable within the chassis (2) to provide space (11) for moving the auxiliary equipment (5) within the chassis (2) along the at least one transportation rail (7) between the first and second position.

A fan tray, for a fan module of a network device chassis, may include an inner assembly that includes an inner cassette, one or more fans connected to the inner cassette, a first latch connected to the inner cassette and configured to removably connect to an outer assembly of the fan tray, and a fan controller connected to the inner cassette and configured to control operation of the one or more fans. The outer assembly may be configured to receive and retain the inner assembly, and may include an outer cassette with one or more openings configured to communicate with the one or more fans, a second latch connected to the outer cassette and configured to removably connect to a rear portion of the network device chassis, and an adaptor connected to the outer cassette and configured to connect and provide power to the fan controller.

Apparatuses and methods are provided for protectively covering an air inlet or outlet of an air-moving assembly. The apparatus includes a protective cover assembly, which includes a retractable cover and a spring-biasing mechanism. The retractable cover transitions between a retracted state, when the air-moving assembly is operatively positioned within the chassis, and in extended state, when the air-moving assembly is withdrawn from the chassis. In retracted state, the retractable cover is retracted away from the air inlet or outlet, and in extended state, the retractable cover covers, at least partially, the air inlet or outlet. The spring-biasing mechanism is coupled to the retractable cover and biases the retractable cover in the extended state when the air-moving assembly is withdrawn from the chassis, and compresses to allow transition of the retractable cover to the retracted state as the air-moving assembly is inserted into operative position within the chassis.

In one embodiment, a modular electronic system includes a front panel comprising openings for receiving a plurality of modules, a removable fan tray comprising a plurality of fans for cooling one or more of the modules with airflow entering the modular electronic system at the front panel when the plurality of fans are operating, and a fan tray channel for receiving the fan tray and positioning the fans in a row generally parallel to the front panel. The channel extends from one of the openings in the front panel and is contained within a horizontal plane in the modular electronic system.

A network device includes a shelf configured to support interface cards on a front side; a control module including a first frame and a printed circuit board disposed to the first frame, wherein the control module is configured to connect on a rear side of the shelf; and a cooling module including a second frame and cooling fans disposed to the second frame, wherein the second frame is configured slidingly connect to the first frame on the rear side of the shelf.

In one embodiment, an apparatus includes a fan tray comprising a plurality of fans for cooling modules within a modular electronic system with airflow from a front of the modular electronic system to a back of the modular electronic system, and a hinge member for connecting the fan tray to a front panel of the modular electronic system with the fans positioned in front of the modules. The fan tray is rotatable on the hinge member for movement away from the front panel to allow for replacement of one of the modules.

A fan gantry includes a frame structure, a supporting structure, a cover body and a thumb screw. The frame structure includes two side walls and a first connecting plate. The side walls define some spaces therebetween. Each side wall has an opening. The openings stagger with the spaces. The first connecting plate is disposed on one side wall. The supporting structure includes two structural plates opposite to each other and connected between the side walls. The structural plates define a channel aligning with the openings and allowing some electric cables to penetrate through. The cover body connects with the frame structure to cover the channel. The thumb screw is disposed on a second connecting plate of the cover body. When the cover body covers the channel, the second connecting plate abuts against the first connecting plate, and the thumb screw locks to the first connecting plate.

In one embodiment, an apparatus includes a module for installation in a modular electronic system. The module generally comprises a subassembly for insertion into a front opening in a chassis of the modular electronic system or removal from the front opening in the chassis and an adapter comprising a first interface for mating with the subassembly and a second interface for mating with the modular electronic system. The adapter remains in the chassis during removal of the subassembly from the front opening in the chassis and the module is configured for insertion into a rear opening in the chassis or removal from the rear opening in the chassis with the subassembly coupled to the adapter.

An equipment enclosure free air cooling assembly includes an air outlet arranged to deliver air to inside an equipment enclosure and an air inlet arranged to receive air from outside the equipment enclosure. An air flow pathway is provided through which air entering the air inlet must pass to reach the air outlet. An adjustable screen assembly has a screen filter element. An adjustment mechanism is operable to selectively utilize different regions of the screen filter element for filtering air passing through the air flow pathway at different times.
