Abstract: A message is simultaneously broadcast to multiple systems on a 1-wire bus. A first addressed communication session is established between a microprocessor and a first 1-wire I/O expander via a 1-wire bus, where the first 1-wire I/O expander is electrically coupled to a first system. The first 1-wire I/O expander is placed into “fast access mode”, and then removed from the 1-wire bus by opening a switch to the 1-wire bus. A second addressed communication session is established between the microprocessor and a second 1-wire I/O expander before the switch recloses, where the second 1-wire I/O expander is electrically coupled to a second system. The second 1-wire I/O expander is then placed into “fast access mode”. In response to the timer expiring and the switch reclosing, an unaddressed message is broadcast from the microprocessor to the first and second systems via the first and second 1-wire I/O expanders.

Abstract: A method and computer program product secure a hot-swap data storage device against being manually physically removed from an operable position within a chassis bay of a computer system. The hot-swap data storage device is released to be manually physically removed from the operable position within the chassis bay of the computer system in response to determining that the data storage device is not active. The hot-swap data storage device may, for example, be secured and released using an electronically-actuated lock.

The terminating resistor assembly provides an elongate conductive bus bar and a plurality of conductive branches, wherein each conductive branch is in electronic communication with the elongate conductive bus bar through a resistor, wherein each conductive branch has a distal end disposed for contacting a signal pin within a memory module socket installed on a printed circuit board. A distal end of each conductive branch is inserted into a window on the connector shoulder adjacent to the slot of an empty memory module socket and engages a plurality of signal pins within the socket in response to the absence of a memory module in the slot. The plurality of signal pins engage contact pads on the memory module and are pushed out of contact with the conductive branch in response to the presence of a memory module in the slot.
