Switch
First Claim
1. An apparatus for a modular computer system, comprising:
- a combined switch and service processor module configured to couple to an information processing module, wherein the combined switch and service processor module includes;
a switch portion;
a service processor portion;
a data interface configured to communicate with an external management entity via a network; and
a fault management unit configured to receive fault messages generated by the switch portion and by the service processor portion, including respective fault messages generated by the switch portion and the service processor portion that relate to a same fault of the information processing module, and wherein the fault management unit is further configured to perform processing on a received fault message to determine whether to forward the received message to the external management entity via the data interface, wherein the fault management unit is configured to not forward fault messages that relate to the same fault for which the fault management unit has already forwarded a fault message to the external management entity;
wherein the apparatus is further configured to detect that the information processing module is outputting erroneous data relating to the same fault, and, in response thereto, to disable further communication of erroneous data by the information processing module.

Abstract
A combined switch and service processor module for a modular computer system is provided. The combined switch and service processor module comprises a switch portion; a service processor portion; and a data interface for communicating management information to other parts of the modular computer system. Wherein the service processor portion is operable to operate in master/slave relationship with a service processor portion of a further combined switch and service processor module of the modular computer system; and wherein the service processor portion is further operable automatically to synchronise management information with the service processor portion of the further combined switch and service processor via the data interface in accordance with the master/slave relationship.

13. A method of operating a combined switch and service processor module for a modular computer system, the combined switch and service processor module having:
-
a switch portion; a service processor portion; a data interface configured to communicate with an external management entity via a network; and a fault management unit;
the method comprising;the fault management unit receiving fault messages generated by the switch portion and by the service processor portion including a first fault message generated by the switch portion and a second fault message generated by the service processor portion, wherein the first and second fault messages relate to a same fault of an information processing module of the modular computer system; the fault management unit performing processing on a received fault message to determine whether to forward the received message to the external management entity via the data interface; the fault management unit not forwarding fault messages that relate to the same fault for which the fault management unit has already forwarded a fault message to the external management entity; the modular computer system detecting that the information processing module is outputting erroneous data relating to the same fault, and, in response thereto, disabling further communication of erroneous data by the information processing module. - View Dependent Claims (19, 20, 21, 22, 23, 26)
