Abstract: A dimmer switch system for dimming a load includes a master dimmer structured to be electrically connected to a power source and the load and to control dimming of the load by regulating power provided from the power source to the load, and at least one accessory dimmer structured to be electrically connected to the master dimmer via a traveler conductor. The master dimmer is structured to generate a first control signal on the traveler conductor to indicate a type of the master dimmer, and the at least one accessory dimmer is structured to selectively enable or disable one or more functions of the at least one accessory dimmer based on the type of the master dimmer.

The master dimmer includes a first visual load status indicator structured to emit light in a plurality of colors. The at least one accessory dimmer includes a second visual load status indicator structured to emit light in a plurality of colors, and is structured to set a color of light emitted by the second visual load status indicator based on a first control signal generated by the master dimmer on the traveler conductor, and to generate a second control signal on the traveler conductor.

Abstract: A data center rack door having a curved permeable member is disposed vertically along a front-face of a data center rack. The curved permeable member provides an increase in surface area that provides for additional openings, increasing airflow through the data center rack. The curved permeable member also provides an increase in volume of space in the data center rack.

Abstract: A telecommunication panel may comprise a chassis configured to receive insertable Digital Signal Cross-connect (DSX) modules and a backplane connected to the chassis. The DSX module is compact to fit into the telecommunication panel. A ratio of the number of the insertable 6-port DSX modules over the backplane surface area at least about 0.37 modules per square inch is achieved. The DSX module may include a printed circuit board and a light emitting diode (LED) light pipe on the printed circuit board to minimize the width of the DSX module. The DSX module may be inserted into the telecommunication panel horizontally or vertically so that the telecommunication panel receives a maximum number of DSX modules.

Abstract: Telecommunications equipment racks are described which are configured to occupy a minimum surface area, offer substantial strength while allowing substantial access to the interior of the rack. In one embodiment, a rack features a plurality of secondary and primary load bearing posts which are configured to allow substantial access to the interior of the rack. The rack may be further configured with a plurality of mountings to engage a plurality of telecommunications equipment within the interior of the rack.

Abstract: A modular telecommunications device that may be configured with a variety of connector types that enable any telecommunications equipment to route signals through the telecommunications device. The device includes a quad jack frame, a main printed circuit board and an interchangeable back plate that can be replaced by another interchangeable back plate that includes a different connector type. A secondary printed circuit board is included in the interchangeable back plate. The incoming power to the device is provided to the main printed circuit that distributes power throughout the device.
