Abstract
A system comprises plural electronic modules, at least one interconnect structure and plural power supplies. The electronic modules communicate over the interconnect structure. The system further comprises plural redundant manager modules to perform management tasks with respect to the at least one interconnect structure and the power supplies.
Claims22
A system comprising:
- plural electronic modules;
- interconnect structures, the electronic modules to communicate over the interconnect structures;
- plural power supplies;
- plural redundant manager modules to perform management tasks with respect to the interconnect structures and the power supplies, wherein the management tasks performed with respect to the power supplies include monitoring health of the power supplies by the manager modules;
- and
- each of the manager modules to control reset of a respective one of the interconnect structures.

6 more elements
A method for use in a system having plural electronic modules interconnected by at least one interconnect structure, wherein the system has plural power supplies, the method comprising:
- performing management tasks with respect to the at least one interconnect structure and the power supplies using plural redundant manager modules, wherein a first of the manager modules is to provide enable signals to respective first power modules in the power supplies, and wherein a second of the manager modules is to provide enable signals to respective second power modules in the power supplies;
- operating the plural manager modules independently of each other such that handshaking among the plural manager modules is not performed;
- and
- after failure of one of the plural manager modules, at least another one of the plural manager modules continuing to perform management tasks with respect to the at least one interconnect structure and at least one of the power supplies to enable continued operation of the system,
- wherein the at least one interconnect structure comprises controllers to perform switching tasks over an interconnect circuit to enable communication between the electronic modules, wherein performing management tasks with respect to the controllers comprises each manager module controlling reset of a respective controller.
2 more elements
A method for use in a system having plural electronic modules interconnected by at least one interconnect structure, wherein the system has plural power supplies, the method comprising:
