Term Definition
power cycle
To power-cycle a device is the act of turning a piece of equipment off and then on again, via its own power switch or directly through the mains input. This could be done manually but is usually automated and can be operated remotely through another device called a Power Distribution Unit (PDU). The reasons for power cycling include having an electronic device reinitialise its configuration or recover from an unresponsive state of its mission critical functionality, such as in a crash or hang situation.
