Abstract
An example device includes a physical interface to connect to a system. The device also includes a power source to deliver power to a diagnostic portion of the system via the physical interface. The diagnostic portion draws a small amount of power. The power source delivers the power based on the system not receiving power from an internal source. The device also includes a reporting engine to communicatively couple to the system via the physical interface. The reporting engine retrieves an indication of whether a cable in the system is connected.
Claims14
A system comprising:
- a cable to connect to a connector;
- a connection detection engine to detect whether the cable is connected to the connector;
- a first power source to power the system, including the connection detection engine;
- a power rail to electrically couple the connection detection engine to a second power source, wherein the second power source is to power the connection detection engine when a voltage rail from the first power source is unpowered and wherein the connection detection engine is to detect whether the cable is connected to the connector based on a static potential on a conductor in the cable;
- and
- a power isolation engine to prevent the second power source from providing power to the first power source and a plurality of components electrically coupled to the first power source.
A method, comprising:
- supplying power from a secondary power source to a diagnostic portion of a system, the diagnostic portion drawing a small amount of power, wherein supplying the power comprises supplying the power based on the system receiving a lack of power from a primary power source;
- and
- detecting, using the power from the secondary power source, a status of a cable connection internal to the system, the detecting based on a static potential on a conductor in the cable.
A device comprising:
- a physical interface to connect to a system;
- a power source to deliver power to a diagnostic portion of the system via the physical interface, the diagnostic portion drawing a small amount of power, the power source to deliver the power based on the system not receiving power from an internal source;
- and
- a reporting engine to communicatively couple to the system via the physical interface, the reporting engine to retrieve an indication from the diagnostic portion of whether a cable in the system is connected based on a static potential on a conductor in the cable.
