A hybrid standby power system for producing regulated DC electrical power, a method of producing such power and a telecommunications installation that employs either the system or the method. In one embodiment, the system includes: (1) a primary power input, couplable to a primary power source, that accepts primary electrical power subject to interruption, (2) a standby power input, couplable to a standby power source, that accepts unregulated standby electrical power and (3) a power converter, couplable to at least one of the primary and standby power inputs, including a rectifier that rectifies at least one of the primary and standby electrical power to provide unregulated DC electrical power and a DC--DC converter that converts the unregulated DC electrical power into the regulated DC electrical power.

The present invention provides, in one embodiment, a system for providing fuel to a backup electrical fuel cell. In this particular embodiment, the system includes a sealed fuel container having a pierceable membrane with a container seal associated therewith, an acerate tube proximate the pierceable membrane, and an actuator. The actuator is coupled to the acerate tube and automatically drives the acerate tube through the pierceable membrane to provide fluid communication from the fuel container to the fuel cell in response to a failure of a primary electrical power system. The container seal is configured to form a seal about the acerate tube when the acerate tube pierces the pierceable membrane to prevent unnecessary loss of fuel, such as methanol, from the container. In alternative embodiments, the system may also include the primary power system and a backup electrical fuel cell that is electrically coupled to the primary power system.

The present invention provides an electromagnetic interference (EMI) module cover for use in an electronics module that is configured to house electrical components that are capable of generating electromagnetic emissions that cause EMI. In one embodiment a conductive sidepanel has a resilient cantilever member formed therefrom with a fixed end that is integrally formed with the sidepanel and a movable end that is free of a module coupler, thereby allowing the resilient cantilever member to flex as the module is installed in a chassis. The resilient cantilever member has a boss that is formed proximate to the movable free end. The boss extends outward from the sidepanel a distance sufficient to provide a conductive path between the conductive sidepanel and an adjacent conductive surface when the module is installed in the chassis.

For use with an electronic equipment chassis having a module support member adapted to receive an electronic module and having a conduit containing an electrical conductor proximate the module support member, an electromagnetic interference (EMI) cover, method of manufacturing the EMI cover and electronic equipment chassis employing the same. In one embodiment, the EMI cover includes a conductive body that substantially conforms to the conduit and a boss extending from the conductive body and configured to contact a conductive case of the electronic module. The boss provides a conductive path between the conduit and the electronic module to establish a common voltage potential therebetween thereby reducing EMI emissions associated with the electronic module.

For use with a rack for supporting a first battery having first terminals and a second battery having second terminals, an interlock kit comprising a partition mount and a partition. The partition mount is couplable to the rack proximate the first battery and the second battery. The partition is coupled to the partition mount and translatable between a first battery access position that allows access to ends of the first terminals and obstructs access to the second terminals and a second battery access position that allows access to ends of the second terminals and obstructs access to the first terminals.

A chassis assembly for receiving power supply modules therein. The chassis assembly includes: (1) a cabinet, (2) an elongated bus bar assembly configured to be supported within the cabinet from a mount coupled to the cabinet, the bus bar assembly having a pair of conductors capable of receiving a terminal connector of a power supply module received into the cabinet and (3) a shelf, oriented laterally with respect to the bus bar assembly, that supports at least one power supply module received into the cabinet, the bus bar assembly being substantially free of terminal connectors and adapted to eliminate a need for support of a portion of a weight of the bus bar assembly apart from the mount.

The present invention is directed to a mounting clip for electronic components and, more specifically, to a component retention spring clip for securing electronic components to an electronic device support such as the leg of a heat sink. In one embodiment the component retention clip is comprised of a resilient strip that has an arcuate portion and first and second ends. The resilient strip is configured to encompass an electronic component and an electronic device support adjacent to the electronic component. The arcuate portion of the component retention clip contacts a portion of the electronic component, thereby partially supporting the electronic component against the electronic device support. Located at the first end of the resilient strip is a first latch configured to cooperatively engage a corresponding second latch located at the second end and retain the electronic component on the electronic device support.
