Technical field
The present invention relates to the power technology of the electronics or the communications field, specifically refer to a kind of system that discerns the veneer redundant power supply.
Background technology
In the power supply design of some product, because the device integrated level on some veneer is than higher, can't place power supply, can only be its power supply by the connector on the motherboard by other veneer, perhaps owing to reliability requirement height to power supply, need other veneer to provide the power supply Hot Spare for it, power to board B as the veneer A among Fig. 1, the veneer A among Fig. 2 provides the power supply Hot Spare for board B.But because described board B is matched in system, and other veneer can be inserted in the plate position at board B place in system, so whether how to discern board B fast and effectively is configured, and for its power supply or Hot Spare is provided, and do not influence the operate as normal of other veneer of system, become the gordian technique that improves the product reliability power supply.
For improving the reliability of product power supply, following two kinds of schemes commonly used in the prior art:
First kind, fixing veneer position, promptly making by fixing veneer position needs the veneer of power supply can only be inserted on the specified slot position, and other veneer can not be inserted on this plate position.
Obviously, above-mentioned first kind of scheme has following shortcoming:
1, owing to after the veneer stationkeeping, can only plug in the veneer that needs power supply,, dispose dumb so when not disposing described veneer, this veneer position can only be vacant, causes the waste of veneer position.
2, poor operability if other veneers are inserted in the position of the veneer that needs power supply by mistake, then can cause other veneers to damage, as seen, and the poor operability of described first kind of scheme.
Second kind, the connector that links to each other on other veneers and the motherboard is defined as sky, principle is: because power supply is to transmit by the connector on the motherboard, if so on other veneer with motherboard on the connector that links to each other be defined as sky, even other veneers are inserted in the position of the veneer that needs power supply, also can damage other veneers by mistake.
Though in second kind of scheme, the veneer configuration is more flexible, but still has following shortcoming:
1, because the part connector on other veneer is defined as sky, causes the wasting of resources;
2, this part connector can only be walked power supply on the motherboard that is defined, and can not walk other signal, and utilization factor is low.
