Abstract
A system for standby power control in a multiple power supply environment is provided. The system includes a plurality of power supplies. Each power supply has a standby voltage output, and has a standby voltage enable signal input. A signal line connects to each power supply at the respective standby voltage enable signal input. A resistance is connected between the signal line and a system reference. The plurality of power supplies are configured such that the resistance determines a number of power supplies that must be available before the standby voltage outputs are activated by the power supplies.
Claims18
A system for standby power control in a multiple power supply environment, the system comprising:
- a plurality of power supplies, each power supply having a standby voltage output and having a standby voltage enable signal input;
- a signal line connected to each power supply at the respective standby voltage enable signal input;
- a resistance connected between the signal line and a system reference;
- and
- wherein the plurality of power supplies are configured such that the resistance determines a number of power supplies that must be available before the standby voltage outputs are activated by the power supplies.
A blade system comprising:
- a blade enclosure;
- a plurality of power supplies disposed in the blade enclosure, each power supply having a standby voltage output and having a standby voltage enable signal input;
- a signal line connected to each power supply at the respective standby voltage enable signal input;
- a resistance connected between the signal line and a system reference;
- and
- wherein the plurality of power supplies are configured such that the resistance determines a number of power supplies that must be available before the standby voltage outputs are activated by the power supplies.
