A data center includes a floor; a side wall configured to partition a space above the floor into a room; a plurality of server columns arranged in a row direction on the floor, each of the plurality of server columns including a plurality of servers that are arranged to form a column in a column direction; an inclined ceiling that increases in height from a first side toward a second side in the column direction; and a first cable tray configured to hold a first cable, the first cable tray being provided in a space below the inclined ceiling on the first side in the column direction, and extending along the row direction.

A communication system may include a first chassis having first and second side walls and adapted to slidably receive therein a plurality of cassettes. A first cable hanger assembly may have a first side edge hingedly coupled to the first side wall of the first chassis, the first cable hanger assembly including a plurality of first hangers adapted to support cables thereon. An axis of rotation of the first cable hanger assembly may be substantially orthogonal to a direction in which the plurality of cassettes are slideable. The cable hanger assembly may be rotatable from a first position to a second position so that during rotation from the first position to the second position, the plurality of first hangers move toward front faces of the plurality of cassettes.

A cabinet is provided, including a case and a fin element. The case has at least one opening. The fin element is disposed in the case and is adjacent to the at least one opening and includes a main body and a plurality of fins, wherein the fins are disposed on the main body and face the at least one opening.

To achieve multiple benefits, a high speed computing system is configured in a hierarchical manner with flexibility and re-configurability concerns maximized. This begins with a particular cabinet architecture which is specifically designed to accommodate various needs and considerations. The cabinet or rack is designed to receive various chassis assemblies depending on the particular needs and or functions involved. These may include a compute chassis, a switch chassis, or a rectifier chassis, which can be incorporated into the cabinet. Within each chassis, specific components are then inserted, with each of these components being in a subsystem configuration. For example, the compute chassis is specifically designed to receive a number of compute blades. Similarly, the switch chassis is designed to receive a number of switch blades. Lastly, the rectifier chassis is configured to receive a number of rectifiers. Collectively, the multiple blades and chassis are all configured to cooperate with one another in an efficient manner. While various subassemblies are utilized, the cabinet or rack does accommodate certain centralized functions such as cooling and power distribution.

Telecommunications closures and systems and associated methods of moving or lifting the telecommunications closures. The closures are provided with one or more protruding gripping features which can be gripped by hand and/or with a tool in order to move or lift the closure without having to grip a telecommunications cable entering the closure.

Disclosed is an audio processing system that includes various audio signal inputs and outputs for producing distributed audio signals for use in audio processing and related applications. The digital and/or analog audio signal processing system includes a rack/chassis containing a central routing card, a plurality of slots for receiving modules and a plurality of inputs and outputs for receiving and producing various processed audio signal inputs and outputs.

A noise reduction door related to a noise reduction device in order to resolve a problem that the noise reduction door cannot meet a requirement for different noise reduction effects and different air duct resistance. The noise reduction door includes a T-shaped mechanical part, two fan-shaped mechanical parts, and a door plate. The T-shaped mechanical part and the fan-shaped mechanical part are connected to the door plate using a detachable connection mechanical part. The T-shaped mechanical part is located on a central axis of the door plate, and the two fan-shaped mechanical parts are respectively located on two sides of the T-shaped mechanical part. Therefore, the fan-shaped mechanical part on the door plate may be changed to have different installation positions and installation manners in order to obtain noise reduction doors in different forms. The embodiments of the present disclosure are applied in cabinet noise reduction.
