Abstract:
1. A remote server management controller, comprising: an Input/Output processor (IOP) that is adapted to communicate with a managed server via a communication interface; a failsafe register that is adapted to receive an IOP reset request via the communication interface; a failsafe boot timer adapted to initiate a countdown when the failsafe register receives an IOP reset request; a plurality of registers associated with the IOP, the plurality of registers being adapted to be accessed by the IOP and to be accessed via the communication interface, the plurality of registers being adapted to be placed in a locked condition in which access to the plurality of registers via the communication interface is prevented, the plurality of registers being adapted to be placed in an unlocked condition in which access to the plurality of registers via the communication interface is permitted; wherein the IOP is adapted to be placed in a reset condition if the IOP does not clear the IOP reset request from the failsafe register and disable the failsafe boot timer before the countdown expires, and wherein the plurality of registers are placed in the unlocked condition if the IOP is placed in the reset condition; and wherein the IOP is adapted to be placed in an operational condition if the IOP does clear the IOP reset request from the failsafe register and disable the failsafe boot timer before the countdown expires, and wherein the plurality of registers are placed in the locked condition if the IOP is placed in the operational condition.
