Abstract
Each modular processor card of a modular electronic system carries a component defining its maximum current or power requirements. The component, which may be a resistor, capacitor, serial access memory, or the like, is accessible over a single conductor through a backplane by a power supervisor. The supervisor will determine the current/power requirements of a processor card while the card is substantially powered off. The supervisor may then weigh existing power supply resources of the modular electronic system with existing current/power demand and make a decision to allow power-up of the card if sufficient overhead is available, or, alternatively, make a decision to deny power-up of the card if insufficient additional current/power resources are available. An optional message indicating the outcome of the decision can be transmitted to a user. If the supervisor elects to power up the card, a signal sent on the conductor connecting the card to the supervisor may be used to authorize the card to power up and control circuitry to effect the power up.
