Abstract: A flow detection device comprises a fluidic input port connected to a fluidic output port via a channel and a float located within the channel. A specific weight of the float exceeds a specific weight of a fluid injected in the flow detection device. Respective locations of the fluidic input port, of the channel and of the fluidic output port on the flow detection device cause the float to rise within the channel when a sufficient flow of the fluid is injected in the flow detection device. A sensor is provided to detect a position of the float within the channel. The flow detection device may be integrated in a cooling circuit having a cooling device for an electronic device to detect an eventual lack of a flow of a cooling fluid in the cooling circuit. A status of the flow of the cooling fluid is reported to a processor.

Abstract: A cooling system comprises a container receiving a dielectric cooling liquid and electronic components immersed in the dielectric cooling liquid. A first pump causes a circulation of a first fraction of the dielectric cooling liquid in the container for convection cooling of the electronic components. A second pump withdraws a second fraction of the dielectric cooling liquid from the container and directs the second fraction of the dielectric cooling liquid toward the electronic components for direct cooling of the electronic components. A manifold fluidly connected to an outlet of the second pump receives the second fraction of the dielectric cooling liquid from the second pump. One or more outlet pipes fluidly connected to the manifold bring portions of the second fraction of the dielectric cooling liquid in thermal contact with the electronic components.

Abstract: A system provides a network interface to electronic components. The system comprises a rack, having a plurality of rack stages, each of which is configured to receive a corresponding electronic component. One peripheral component interconnect express (PCIe) connector corresponds to each rack stage and is connectable to the corresponding electronic component when received in the rack stage. The PCIe connectors are assembled in a PCIe connector group. Each PCIe connector of the PCIe connector group has a same number of active serial links. The system also comprises a network adaptor that provides a serial link termination for each active serial link of the PCIe connector group. The network adaptor comprises a communication interface for communicating with a network. The network adaptor is configured to multiplex signals exchanged between the network and the PCIe connectors of the PCIe connector group.

Abstract: A power distribution circuit for providing electric power from a plurality of power supplies to a plurality of loads comprises a combiner of power outputs of the power supplies to provide power at a given voltage to a plurality of hot swap modules that are each electrically connected to the combiner and to a power input of a corresponding load. Each hot swap module verifies one or more conditions selected from the given voltage being at least equal to a minimum voltage threshold, the given voltage not exceeding a maximum voltage threshold, and a current consumed by the load not exceeding a maximum current threshold. Each hot swap module delivers power to the power input of the corresponding load when all selected conditions are met and isolates the power input of the corresponding load from the power supplies when any one of the selected conditions is not met.

Abstract: A cooling arrangement for an electronic device comprises a primary cooling device and a secondary cooling device. The primary cooling device includes a fluidic input line receiving a cooling fluid from a cooling fluid source and a fluidic output line returning the cooling fluid toward a drain. The primary cooling device is thermally connected to the electronic device, receives the cooling fluid from the fluidic input line and transfers heat from the electronic device to the cooling fluid before returning the cooling fluid via the fluidic output line. A flow detection device monitors a flow of the cooling fluid in the primary cooling device. The secondary cooling device is thermally connected to the electronic device. A processor activates the secondary cooling device to absorb and dissipate heat from the electronic device when the flow detection device detects a lack of flow of the cooling fluid in the primary cooling device.

Abstract: Delivery of power to one or more servers is controlled by energizing a control circuit and transmitting, from the control circuit to a first power source, a first signal indicating that the control circuit is energized. After transmitting the first signal indicating that the control circuit is energized, the control circuit receives a second signal indicating that the first power source is ready to provide power. The control circuit also receives, from a server, a third signal indicating that the server is energized. Having received the second signal indicating that the first power source is ready to provide power and the third signal indicating that the server is energized, the control circuit transmit to the server a fourth signal indicating that the server may start receiving power from the first power source.
