Method and apparatus for providing early warning of extraction of module under power
Abstract:
An apparatus includes a connector configured to be electrically coupled to electrical circuitry. The connector has multiple pins, including one or more first pins and one or more second pins. The one or more second pins longer than the one or more first pins. The apparatus also includes a signal generator configured to detect disconnection of the one or more first pins prior to disconnection of the one or more second pins and generate a signal in response to detecting the disconnection of the one or more first pins. The connector could also include one or more third pins longer than the one or more second pins. The first pin(s) can create an electrical path from the signal generator to ground, the second pin(s) can provide a supply voltage to the electrical circuitry, and the third pin(s) can electrically couple the electrical circuitry to ground.
