International Classification:

H05H 720

US Classification:

361724, 361727, 361790, 248 65, 360 978

Abstract:

A system to mount several electronic devices within a one EIA unit high rackspace is presented. The system includes a mounting chassis that is securely fastened to a standard 19â EIA electronics rack. The chassis includes dividers that define at least two full length ports in which the electronic devices are slidably engaged. Furthermore, each port defined by the mounting tray includes hot-pluggable, blind-mate sockets to receive corresponding hot-pluggable, blind-mate connectors upon each electronics package. These packages are engaged and disengaged to and from the ports within the rack at will, thus allowing for more servers to be efficiently and accessibly stored within the confines of a 1-U rackspace with interchangeability than was previously possible.

International Classification:

H05K 500

US Classification:

361687

Abstract:

A DC distribution module for a power supply unit is modular and facilitates thermal cooling of the unit. The power supply unit preferably includes a housing in which one or more power supply modules and the DC distribution module can be inserted. The DC distribution module preferably comprises two power conductors laminated and bonded to a ground conductor. The DC distribution module is relatively thin compared to the power supplies inserted into the power supply unit. By being relatively thin, the DC distribution module, which may carry substantial amounts of current, does not substantially interfere with air movement through the power supply unit for thermal cooling purposes.

International Classification:

G06F 116

US Classification:

361725, 361683, 361733, 3122232

Abstract:

A power supply unit includes a housing in which one or more power supply modules can be inserted and a modular AC input section. The modular AC input section preferably attaches to the distal end of the housing from where the power supply modules are inserted. The AC input section includes one or more circuit breakers, connectors and wiring connecting the breakers to the connectors. The connectors preferably comprise blind mating connectors that mate with corresponding connectors on the rear surface of the power supply modules. The AC input section is screwed to the power supply housing or attached through some other suitable means. The AC input section is modular in the sense that it can be easily and quickly removed from the power supply unit and replaced with another section. This permits upgrades and repairs to be made in a quick, cost effective manner.

International Classification:

A47F 7/00

US Classification:

211 26, 2111311, 3123344

Abstract:

A rail mounting arrangement for supporting a computer component, such as a server, in a rack includes a pair of support rails and slide rail assemblies supported by the support rail. The support rails are identical and include a pair of mounting regions on either side of a longitudinal axis. The slide rail assemblies have a lower profile than the support rails and may be mounted on either of the mounting regions. The slide rail assemblies are secured to the server and present a low profile, permitting greater access to internal components within the server housing for servicing. The support rails are recessed in the rack to reduce the space occupied by the rail system in the region of the rack in which the server is supported.

US Classification:

174 50, 174520, 361679, 3122231

Abstract:

The described embodiments relate to electronic devices. One exemplary device includes a pair of sidewall components extending between respective top portions and bottom portions, the bottom portions lying in a plane that extends between the bottom portions. The device also includes a bottom component joined with and extending between the bottom portions, wherein the bottom component has a non-loaded disposition relative to the plane and a loaded disposition relative to the plane, and wherein at least a portion of the bottom component is closer to the plane in the loaded disposition than in the non-loaded disposition.

International Classification:

A47F 700

US Classification:

211 26

Abstract:

In a rack-mounted computer system a server unit drawer structure is mounted between spaced pairs of front and rear corner support channel portions of the server cabinet using a pair of specially designed slide support brackets, each positioned on a different side of the drawer structure and extending completely between its associated pair of front and rear corner support channels. Front ends of the brackets have vertically spaced alignment tabs that are complementarily received in openings in side flange portions of the front corner channels and serve to precisely align the front bracket ends, and thus the front end wall of the drawer structure, with the cabinet framework in both horizontal directions. The front and rear ends of the brackets are secured to their associated support channels with threaded fasteners. The drawer is slidably mounted on the installed brackets using a conventional telescoping slide structure having a front end portions secured to opposite side walls of the drawer, and rear end portions secured to the brackets.

US Classification:

Abstract:

A series of hard disk drives are anchored to the top sides of perforated metal plates disposed above the top sides of molded plastic support trays in parallel relationships therewith. Sets of spaced apart elastomeric cushioning members have upper portions captively retained between each metal plate and its associated plastic tray, and lower portions projecting downwardly beyond the tray. Small connector circuit boards are anchored to rear end portions of the metal plates, and opposite side edge portions of the plates are slidably insertable into guide channel members within a cage structures to create a hot plug connection between the circuit boards and corresponding hot plug connectors on a rear wall of the cage. Ramped alignment projections formed on the opposite plate side wall portions automatically compensate for vertical and horizontal dimensional variations in the tray supporting portions of the cage; the elastomeric members function to reduce handling shock transmitted to the mounted disk drives; and the metal plates form underside EMI shielding structures for the mounted disk drives.
