A space creating shower liner can have a window with a hoop fin rotatably and removably engaging a shower rod, a plurality of stiffening folds providing partial stiffness to the window, and a height less than a distance from the shower rod to a tub. Further, a liner can be removably engaged to the window, comprising a liner height less than the distance from the shower rod to the tub. The hoop fin causes the window and the liner to rotate about the shower rod, and the height and the liner height is greater than or equal to the distance from the shower rod to the tub.

An example electrical connector includes a magnetic core embedded in the overmold and encircling conductive paths therein and a Hall-effect sensor embedded in the overmold and configured to sense a magnetic field of the magnetic core. The Hall-effect sensor generates an output that indicates whether or not the supply current flowing through the connector matches the return current flowing through the connector, and this output may be used to detect stray-current faults in which current bypasses the connector to return via alternative paths such as through a device chassis. The connector may include one or more supply wires embedded in the overmold, one or more return wires embedded in the overmold, one or more supply terminals embedded in the overmold and terminating the supply wires, and one or more return terminals embedded in the overmold and terminating the return wires. The magnetic core embedded in the overmold may encircle (a) the supply terminals or the supply wires or both, and (b) the return terminals or the return wires or both.

Systems and methods are provided for providing thermal protection to a power backplane printed circuit board. A distributed hotspot detection grid is included in the printed circuit board, the distributed hotspot detection grid comprising a plurality of passive temperature sensors spread across the printed circuit board to measure temperature increases. The plurality of passive temperature sensors are connected to a detection circuit for comparing signals from the passive temperature sensors to a reference signal. If the temperature increases on the PCB, electrical characteristics of at least one passive temperature sensor will change, resulting in a change of the input signal to the detection circuit. When the threshold is exceeded (indicating a potential short circuit or hotspot), the detection circuit outputs a shut down signal to the one or more power supplies connected to the of the backplane printed circuit board, to avoid catastrophic damage to the printed circuit board.

Various examples described herein provide for determining a first data input/output (I/O) type of a computing device module and a second data I/O type of an I/O switch module, where the computing device module and the I/O switch module are coupled through a backplane system that includes a retimer. In response to the first data I/O type matching the second data I/O type, a connection between the computing device module and the I/O switch module may be permitted or prevented via the retimer.

Example implementations relate to a server node shutdown. For example, a system includes a control module and a secondary power supply. The control module includes a detect engine to detect an even that triggers a sequenced shutdown of a server node and prevent execution of the sequenced shutdown and execution of a data transfer. The control module also includes an initiate engine to initiate a data backup process, by a basic input/output system (BIOS) of the server node, to write data from a volatile memory location of the server node to a non-volatile memory location of the server node. The secondary power supply is to support the data backup process.

Server node shutdown

Various examples described herein provide for causing operation of a cooling system of a computing device to be adjusted (e.g., reduced or disabled) during at least a portion of a backup operation, where data is copied from volatile memory of the computing device to non-volatile memory of the computing device. Some examples can be implemented with respect to a type 10 (T10) non-volatile dynamic inline memory module (NVDIMM) configuration.

According to an example, a server may include a housing including a bottom portion, a first node defined by first and second printed circuit assemblies, and a second node defined by third and fourth printed circuit assemblies.

A test and diagnostics circuit, methods and systems are described. An example test and diagnostics circuit includes a controller and a power monitor coupled to the controller. A load switch on the test and diagnostics circuit selectably implements a load from among multiple load values to test a computing and/or data storage system. The test and diagnostics circuit includes circuitry connecting the controller, the power monitor and the load switch to receive a test enable signal from a non-dedicated pin in a non-volatile dual inline memory module (NV-DIMM) slot to implement a test operation on the system.

Example implementations relate to a parallel backup power supply. For example, a parallel backup power supply system can include a plurality of backup power supply cells that support a plurality of loads. Each of the backup power supply cells can include a charging module to charge an associated backup power supply cell among the plurality of backup power supply cells and a cell controller. The cell controller is to can be configured to control the charging module and communicate with a management module. The parallel backup power supply system can also include the management module to activate each of the plurality of backup power supply cells to provide backup power in parallel to the plurality of loads as each of the plurality of backup power supply cells is fully charged.

Examples herein disclose receiving a communication indicating a number of loads supported by multiple nodes and determining an amount of power available at a backup power source. Based on the determination of the amount of power, the examples disclose delivering power to the multiple nodes from the backup power source.

Example implementations relate to combined backup power. For example, a system for combined backup power can include a combined backup power supply (CBPS) coupled to a node and a plurality of loads supported by the node. The CBPS can include an uninterruptible power supply (UPS) and a backup power supply coupled to the UPS to act as redundancy for the UPS.

An example may include a battery module, and a back-up power control module to determine a back-up power demand of a host device and selectively enable an output of power from the battery module to the host device if the battery module has a power capacity greater than the back-up power demand.

In one example, a processor may include a processor core with a central processing unit as well as a processor cache separate from the processor core. The processor may also include flushing circuitry. The flushing circuitry may identify a power loss event for the processor. In response, the flushing circuitry may selectively power the processor by providing power to the processor cache but not to the processor core. The flushing circuitry may further flush data content of the processor cache to a non-volatile memory separate from the processor.
