This application provides a router. A shielding portion is formed by extending outward an end of a housing where a rotary shaft seat is disposed. The rotary shaft seat is disposed on a side of the shielding portion facing a back of the housing. An end of the shielding portion away from the housing extends to at least a side of the rotary shaft seat away from the housing, so as to shield a front of the rotary shaft seat. In this way, the rotary shaft seat is invisible in a conventional viewing angle, that is, a viewing angle from a front of the router.

Methods and systems automatically protect radio network equipment in extreme weather conditions such as sand-storms or snow-storms. A pair of phase-shift material grids having different orientations is installed at an air intake of the radio network equipment. One of the grids is powered to open or close the air intake according to a current amount of air-carried particles entering the radio network equipment and a temperature inside the radio network equipment. The current amount of air-carried particles entering the radio network equipment may be detected by a piezoelectric sensor.

A system includes an alarm processing module that is configured to receive a plurality of alarm signals that are generated based on conditions associated with an electronics cabinet. Each of the plurality of alarm signals has an alarm state and an ambient state associated therewith. The alarm processing module is further configured to generate an alarm notification signal in response to at least one of the plurality of alarm signals being in the alarm state.

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.

The present invention includes a mobile data power and lighting distribution station (10) and a data, power and lighting distribution system (250). The Station (10) has a plurality of power over ethernet sources (114, 136, 156) for powering LED lights (178, 190, 192, 204) and for providing 240 V AC power via charging station 216 and conversion module 228. Station 10 also communicates data/network connectivity for communicating with IP enabled devices including cameras (196), sensors (198, 166, 200) and for communicating and controlling access control systems (202). Station 10 is controlled via touchscreen (116) or remotely via web based interface made available via local wireless network (118) or via a telecommunications network (126) including the internet (128). The invention also encompasses driverless LED light fixtures controlled directly from the station (10) as well as DALI enabled Ethernet powered LED light fixtures.

A cable management system for a network cabinet has first and second server equipment rails, first and second air dams, and a front cable support. The server equipment rails are mounted to a base frame of the network cabinet such that the server equipment rails extend from the base frame towards a front of the network cabinet. The air dams are mounted to the base frame of the network cabinet such that the air dams extend from the base frame towards opposing sides of the network cabinet. The front cable support has a generally U-shaped tray that is connected to the first and second server equipment rails such that the tray extends across a front of the network cabinet, transverse to the server equipment rails.
