Abstract
A method and apparatus are provided for controlling delivery of electrical power to a hot swappable device. In a system that accepts hot swappable devices, a sensing circuit is provided to detect the hot swappable device being inserted into the system. The sensing circuit provides a signal indicative of the hot swappable device being inserted and a controller blocks delivery of system voltage to the hot swappable device for a preselected duration of time.
Claims21
A system, comprising:
- means for detecting a device being inserted into the system;
- means for blocking delivery of an electrical signal to the inserted device for a first preselected duration of time.
A method, comprising:
- detecting a device being inserted in a system;
- and
- blocking delivery of an electrical signal to the inserted device for a first preselected duration of time.
A system, comprising:
- a sensor adapted to detect a device being inserted into the system;
- a controller adapted to block delivery of an electrical signal to the inserted device for a first preselected duration of time.
An apparatus, comprising:
- a printed circuit board;
- a sensing circuit adapted to detect a device being electrically coupled to the printed circuit board and provide a first signal indicative thereof;
- a controller associated with the printed circuit board, the controller being adapted to receive the first signal and block delivery of electrical power to the device for a first preselected duration of time.
A system, comprising:
- a sensor adapted to detect a hot swappable device being inserted into the system;
- a controller adapted to block delivery of system voltage to the hot swappable device for a first preselected duration of time.
An apparatus, comprising:
- a printed circuit board having a connector adapted to receive a device therein;
- a sensing circuit adapted to detect the device being coupled to the connector and provide a first signal indicative thereof;
- a controller associated with the printed circuit board, the controller being adapted to deliver electrical power to the connector a preselected duration of time after receiving the signal from the sensing circuit.
