Abstract: In some examples, a power adapter for sharing redundant power comprises a primary power input; a redundant power input; a redundant power supply identification signal (RPS ID) input; and a controller coupled to the RPS ID input. The controller is to direct power from the primary power input to an electronic device; direct power from the redundant power input to the electronic device, to another power adapter, or both; modify an RPS ID from the RPS ID input in response to directing power from the redundant power input to the electronic device; and output the modified RPS ID to the another power adapter.

Abstract: Example implementations relate to power supply controllers. In some examples, a controller can include instructions to: set a power threshold for a power supply coupled to a computing component when the computing component is operating in a first state, determine when the computing component is alternating from the first state to a second state, and allow the power supply to exceed the power threshold for a fixed period of time in response to the computing component alternating from the first state to the second state.

Abstract: An example of an apparatus may include an input connection to receive a pulse-width-modulated signal. The pulse-width-modulated signal may control a speed of a fan. An output connection may provide a tachometer signal to indicate the speed of the fan. A controller may provide an identification signal via the output connection. The identification signal may be provided in response to receipt of a predetermined duty cycle via the pulse-width-modulated signal. The identification signal may provide an identification corresponding to the fan.

Abstract: An example of an apparatus with an input connection to receive an input tachometer signal. The input tachometer signal may include a frequency to indicate a fan speed. A pulse width modulator may be coupled to the input connection and generate an output tachometer signal. The output tachometer signal may comprise an output frequency and a duty cycle. The output frequency may be based on the frequency of the input tachometer signal, and the duty cycle may indicate an identification corresponding to the fan.

Abstract: A mechanical interlock for securing a cover to a housing may include a cover latch coupled to a wall of a housing, and a spring biasing the cover latch in a first direction and coupled between the wall of the housing and the cover latch. The mechanical interlock may further include an arm coupled to the cover latch at a first end of the arm, and an electrical socket aperture defined within the wall of the housing juxtaposed to a second end of the arm. When the cover latch is returned to the first position via the spring after the cover is removed from the housing, the arm permits for the electrical cord to interface with the electrical socket.
