Abstract
A chassis controller can identify a blade that spans more than one power plane. If power is healthy and available on all power planes then the blade may be granted permission to power on. The chassis controller validates that when a blade spans multiple power planes that the necessary power is available before permitting the blade to go to fully power operation.
Claims6
A chassis comprising:
- a plurality of slots each slot capable of receiving a blade;
- a mid-plane coupled to the plurality of slots for providing power connectors and electrical signal connectors for each slot;
- a first power module for supplying DC power to a first number of slots;
- a power module receptacle adapted for receiving a second power module for supplying DC power to a second number of slots;
- a multi-slot blade with at least one power connector for each slot occupied by the multi-slot blade, the multi-slot blade having at least one electrical signal interface for communicating with a chassis controller;
- a chassis controller electrical coupled to each slot via electrical signal interface, the chassis controller in response to insertion of the multi-slot blade determines that all slots occupied by the multi-slot blade are powered properly prior to permitting the multi-slot blade to go to full power mode.
