ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to power distribution devices, and, in particular, power distribution devices for use within telecommunications systems, which utilize electronic chassis.
BACKGROUND OF THE INVENTION
Within the telecommunications arena, the electronic chassis of power distribution devices are usually mounted on a rack within the central telecommunications offices. These rack-mounted devices, which are intended for use within telecommunication control offices, must conform to a series of Bellcore standards, in an effort to maintain uniformity in application. One such uniform standard concerns 19.000 inch wide equipment racks. These racks are typically found in Level Four switch rooms, and are most prevalent in Northeastern United States cities, such as New York and Boston. The 19.000 inch requirement, however, does maintain a distinct drawback: The available space for data transmission circuitry (also known as the density of the electronic chassis) is drastically reduced. As a result, the efficiency of the electronic chassis is similarly reduced. However, space is available outside the periphery of the electronic chassis. Thus, if a design could be utilized to take advantage of such presently wasted space, efficiency, as well as density, can be increased tremendously. In other words, a design that could get the power and performance of the 23.000 inch rack-mounted device from a 19.000 inch rack-mounted device. Accordingly, it would be desirable to have a power distribution device attached to an electronic chassis that would resolve the above problems and still be simple and efficient to operate.
SUMMARY OF THE INVENTION
One aspect of the invention provides a power distribution apparatus including an electronic chassis, a power distribution member and a first power supply. The electronic chassis includes a front wall, a back wall and first and second side walls. The electronic chassis may further include a first opening disposed along a top portion of the first side wall and a fan tray positioned along a top member of the electronic chassis. The electronic chassis, may, for example, have a width of 19.000 inches, and is operably mounted to a 19.000 inch standard rack mount. The power distribution member is positioned within the electronic chassis between the first and second side walls. The first power supply is mounted to an outer surface of the first side wall. The first power supply may include an outer shell. The outer shell may include a bottom opening and a top opening. The first power supply may include first, second and third openings, first and second hook ends, first and second input terminals and a main power supply PC board. A second power supply may be mounted to an outer surface of the second side wall.
A further aspect of the invention provides a method of operation of a power distribution apparatus. The method includes the steps of providing an electronic chassis, a power distribution member and a first power supply. The electronic chassis includes a front wall, a back wall and first and second side walls. A first opening and a fan tray may be disposed along a top portion of the electronic chassis. The power distribution member is positioned within the electronic chassis between the first and second side walls. The first power supply is mounted to an outer surface of the first side wall. An outer shell may be disposed within the first power supply. First, second and third openings may be disposed on the first power supply. The first power supply may also include first and second hook ends, and a main power supply PC board disposed therein. A second power supply may be mounted to an outer surface of the second side wall. Power is distributed from the first power supply to the power distribution member. Power may also be distributed from the second power supply to the power distribution member. Air may be drawn up through the first power supply from the bottom opening to the top opening. Air may also be drawn into the electronic chassis through the first opening. Air may be forced out of the electronic chassis and the first power supply and through the fan tray. The first power supply may be operably electronically connected to the power distribution member. The main power supply PC board may be operably electronically connected to the first and second hook ends.
A further aspect of the invention provides a power distribution apparatus including an electronic chassis, a power distribution member and first and second power supplies. The electronic chassis is operably mounted to a 19.000 inch standard rack mount, has a width of 19.000 inches and includes a front wall, a back wall and first and second side walls. A first opening, a second opening and a fan tray may be disposed along a top portion of the electronic chassis. The power distribution member is positioned within the electronic chassis between the first and second side walls. The first power supply mounted to an outer surface of the first side wall. The second power supply is mounted to an outer surface of the second side wall. The power supplys may include an outer shell. The outer shells may include a bottom opening and a top opening. The power supplies may also include first, second and third openings, first and second hook ends, first and second input terminals and a main power supply PC board.
The invention provides the foregoing and other features, and the advantages of the invention will become further apparent from the following detailed description of the presently preferred embodiments, read in conjunction with the accompanying drawings. The detailed description and drawings are merely illustrative of the invention and do not limit the scope of the invention, which is defined by the appended claims and the equivalents thereof.
