A switch cabinet arrangement and method with at least one IT rack or switch cabinet housing and with at least one cooling device, which has an air-liquid heat exchanger for cooling components accommodated in the IT rack or switch cabinet housing with cooled air, wherein the air-liquid heat exchanger includes a first flow for cooled liquid and a first return for heated liquid, wherein the cooling device includes a liquid-liquid heat exchanger, to the second flow of which the first return of the air-liquid heat exchanger is connected.

A computing device is secured in an enclosure by a locking mechanism. The locking mechanism includes a jaw, a transmission lever, and an arm. The jaw is configured to abut a portion of the enclosure for holding the computing device. The transmission lever includes an arm pivot at one end and an actuating pivot at the opposite end. The arm is configured to rotate open and closed about the arm pivot and be selectively decoupled from the transmission lever. When the arm is coupled to the transmission lever, opening the arm causes the transmission lever to rotate open about the actuating pivot. Rotating open the transmission lever about the actuating pivot releases the jaw from the portion of the enclosure, and allows the computing device to be removed from the enclosure.

A fiber distribution hub configured to house a patch panel includes a plurality of walls forming a chamber, a first shelf attached to a first wall of the plurality of walls in the chamber, a first track supported by the first shelf, and a frame body configured to support the patch panel and to be coupled with the first shelf via the first track. The frame body is configured to shift along the first track between a stored position, a front-exposed position, and a back-exposed position.

A bracket may include a structural portion including at least one relatively rigid first material, and a sealing portion including at least one relatively elastic second material. The bracket may also include a first receiver including a first retainer portion configured to be coupled to an end of a first frame member, and a first sealing interface configured to provide a substantially fluid-resistant seal between a portion of the end of the first frame member and the first receiver. The corner bracket may also include a second receiver substantially parallel to the first receiver and including a second retainer portion configured to be coupled to an end of a second frame member, and a second sealing interface configured to provide a substantially fluid-resistant seal between a portion of the end of the second frame member and the second receiver. The bracket may be incorporated into a cabinet frame.

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 telecommunication cabinet with anti-theft function includes a cabinet body, a cabinet door, a fan module, and a plurality of coupling parts. The cabinet body includes a cabinet and a telecommunication module. The cabinet door covers the cabinet body and is provided with a snap hole. A bottom side of the cabinet door is provided with an installation opening. The fan module includes multiple fans and an elastic clip, and the elastic clip is provided with a bump. When the fan module is placed into the cabinet door from the installation opening, the bump is positioned in the snap hole. The fan module is coupled to the bottom side of the cabinet door.

In accordance with some aspects of the disclosure, a modular telecommunications patch panel system is shown and described. The panel can include a mounting frame extending between a first end and a second end, the mounting frame defining a plurality of apertures for receiving telecommunications components, a first mounting ear forming a snap-fit connection with the mounting frame first end, in a first orientation, and a second mounting ear, identical to the first mounting ear, forming a snap-fit connection with the mounting frame second end, in a second orientation.

A locking mechanism for securing a computing device in an enclosure includes a jaw, a transmission lever, and an arm. The jaw is configured to abut a portion of the enclosure for holding the computing device. The transmission lever includes an arm pivot at one end and an actuating pivot at the opposite end. The arm is configured to rotate open and closed about the arm pivot and be selectively decoupled from the transmission lever.

Rotating open the transmission lever about the actuating pivot releases the jaw from the portion of the enclosure, and allows the computing device to be removed from the enclosure.

An example small cell telecommunication structure includes a cabinet opening both on a first side and on a second side. The first side of the cabinet is disposed opposite to the second side. A structural backplane is provided within the cabinet. The structural backplane is made of a single slotted and tabbed flat sheet formed into a first sidewall, a back wall, and a second sidewall. The first sidewall is parallel to the second sidewall, and both the first and second sidewalls are perpendicular to the back wall. An electronics enclosure is provided within the cabinet, having an interior space formed by the first and second sidewalls and the back wall of the structural backplane for housing telecommunications equipment. A power panel is disposed on the second side of the cabinet for providing electrical connections for the telecommunications equipment.
