An apparatus comprising: a drive carrier assembly (DCA) including; an energy storage device having at least a portion thereof encased by a housing; and a printed circuit assembly to detect a power failure of a host computing device, wherein the printed circuit assembly has a first portion coupled to the energy storage device and a second portion coupled to a backplane of the host computing device.

Device carrier assemblies

According to some examples, solutions are provided for power distribution of input alternating current (AC) power to at least one power outlet while the input AC power is available, charging of a set of batteries by the input AC power while the input AC power is available, and power distribution of direct current (DC) power from the set of batteries to the power outlet when the input AC power is not available. For such examples, the power outlet is capable of conducting AC power and DC power to a load that is coupled to the power outlet and that can receive either AC power or DC power.

Power distribution with batteries

An example apparatus comprises a drive carrier assembly which may include a memory device, and an energy storage device having at least a portion thereof encased in a housing. In some examples, the apparatus may include a printed circuit assembly to detect a power failure of a host computing device. The printed circuit assembly, may have a first portion coupled to the energy storage device and a second portion coupled to a backplane of the host computing device.

In one example, a system for bypass switch control includes a controller coupled to a number of backup power modules and to a number of bypass switches that correspond to each of the number of backup power modules, wherein the controller activates a bypass switch when a corresponding backup power module is deactivated.

Bypass switch control

In one example, a system for parallel output of backup power modules includes a first backup power module coupled to an input and a first output of an enclosure, a second backup power module coupled to the input and a second output of the enclosure, wherein the second backup power module is coupled in parallel with the first backup power module, and a switch coupling the first backup power module and the first output of the enclosure to the second output of the enclosure.

Parallel output of backup power modules

Systems, methods, and computer-readable and executable instructions are provided for moderating a charging for a number of power resources. Moderating a charging for a number of power resources can include calculating a distinct charging window for each of the number of power resources. Moderating a charging for a number of power resources can also include selecting a first power resource from the number of power resources based on a current time and the distinct charging window for the first power resource. Furthermore, moderating a charging for a number of power resources can include charging the first power resource within the distinct charging window before charging a second power resource.

Deep-charging power resources of power resource group having identifier corresponding to range within which modulo falls based on charging time

Examples described herein relate to power distribution units (PDUs) with receptacles on one surface and branch rated circuit protection devices on an opposite surface. For example, a PDU includes a first surface including a plurality of receptacles to couple a plurality of electronic devices to the PDU. The PDU also includes a second surface, opposite the first surface, including a plurality of branch rated circuit protection devices associated with the plurality of receptacles.

According to some examples, a bay is provided to receive at least a portion of a housing of a removable device, where the bay includes a management controller to communicate a management signal to the removable device received by the bay, and a cooling mechanism to provide airflow to the removable device received by the bay. The removable device may be one that receives an optical cable, receives an electrical cable, converts a first optical signal received through the optical cable to a first electrical signal transmitted through the electrical cable, and converts a second electrical signal received through the electrical cable to a second optical signal transmitted through the optical cable.

Bay for removable device

Systems, methods, and other embodiments associated with event based correlation of power events are described. One example method includes storing a power distribution unit (PDU) event data that identifies an occurrence of a suspected power event associated with a device. The method can then provide a PDU-server correlation signal that identifies a connection between a PDU and a device.
