Patent ID: 7383461

Claim:
A method comprising: attempting to download computer code from a management module to a first data processing unit, the first data processing unit being one of a plurality of data processing units managed by the management module, the plurality of data processing units being coupled to the management module by a management pathway; in response to the computer code failing to properly download and thus resulting in the first data processing unit being unable to define its management pathway location on the management pathway, transmitting a failure signal from the first data processing unit to the management module using a special address on the management pathway; comparing management pathway locations of currently active data processing units with a list of all management pathway locations reserved for all of the plurality of data processing units, the currently active data processing units being from the plurality of data processing units; deducing the first data processing unit's management pathway location as being a management pathway location that is on the list of all management pathway locations but is not a management pathway location of one of the currently active data processing units; identifying a second data processing unit that does not know its management pathway location as a result of a failed computer code download; blocking communication from the management module to the second data processing unit; providing a first management pathway location to the first data processing unit; subsequently unblocking communication between the second data processing unit and the management module; and providing a second management pathway location to the second data processing unit.
