摘要:
An auxiliary power control system for enabling a software command that a management controller sends to the power supply to shut down auxiliary power. Such a power control system enables an AC cycle without needing to physically remove an AC power cord and provides additional power savings when a system is not in use. In certain embodiments, the auxiliary power control system includes a paradigm of a main power state, an auxiliary power state and a sub-auxiliary state. In this system many of the power states and wake vents apply to the auxiliary power state in addition to the main power state.

An escape sequence coded in power commands from a system controller, such as a BMC, to a cooling fan controller directs the cooling fan to send identification information coded in tachometer readings to the system controller for use by an information handling system. Electronic confirmation of the cooling fan identification ensures compatibility of the information handling system and cooling fan at initial manufacture or subsequent repair. Communication of information over existing power and tachometer wires supports the electronic confirmation without adding additional communication lines. Further, once a communication link is established between an information handling system controller and a cooling fan, other functions are enabled, such as a reflash of the cooling fan controller firmware.

A method is provided for wireless communication. The method includes communicating from a first unit to a second unit a plurality of transition signals. Each of the transition signals has a sequential value. The method further includes transitioning the first unit and the second unit from a first state to a second state simultaneously based on the sequential values of the transition signals.

System and methods for controlling power delivery to system components are disclosed. A controller is communicatively coupled to a point-of-load converter through a first communication path and a shared memory is communicatively coupled to the point-of-load converter through a second communication path. A third communication path communicatively couples the controller and the shared memory. Control data is communicated from the controller to the point-of-load converter through the first communication path and measurement data is written from the point-of-load converter to the shared memory through the second communication path. The controller is operable to read the measurement data from the shared memory through the third communication path.

A communication system includes a storage operable to host an operating system and a management controller configured to directly communicate with the operating system. The management controller directly communicates with the operating system through a communication channel free of an intermediate agent. The management controller is operable to asynchronously send management information to the operating system over the communication channel. The management controller is also operable to asynchronously receive management information from the operating system over the communication channel.

In one embodiment, an information handling system may include a processor, a display that may provide a user interface allowing a user to select one or more system utilities to be accessed, memory that may include a plurality of memory partitions storing a plurality of system utilities, and a management controller. During a configuration of the information handling system, the management controller may receive a request from the user via the user interface to access one or more selected system utilities; identify one or more memory partitions storing the one or more selected system utilities; and cause the display to display one or more user-selectable icons corresponding to the one or more identified memory partitions to provide the user access to the one or more identified memory partitions.
摘要:
A method of using BIOS information can include exporting first BIOS information from a first information handling system. The method can further include initiating a boot sequence for the second information handling system and importing second BIOS information into a second information handling system after initiating the boot sequence and before initiating an operating system, wherein the second BIOS information is associated with the first BIOS information. The method can further include initiating an operating system of the second information handling system after importing the second BIOS information. The first and second BIOS information may be the same, or the second BIOS information may be derived from the first BIOS information. The first and second information handling systems may be the same or different. In one embodiment, the first BIOS information can be translated into a text file for editing before using the second BIOS information during a boot sequence.
摘要:
A system and method and method for filtering communications at a network interface controller is provided. The network interface controller is coupled to a baseboard management controller through a sideband communications channel. The network interface controller filters packets to the baseboard management controller on the basis of the address within the packet that identifies the device that caused the packet to be generated. The network interface controller transmits to the baseboard management controller only those packets that were generated in response to a command issued by the baseboard management controller.

A method and system are provided for synchronizing wireless communication devices. The method and system involve providing a first unit and a second unit for communication over a wireless communication link. Further, an identical identifier is assigned to the first and second units. Also, a data message is constructed having control data. The data message includes a plurality of data bytes and a portion of the control data corresponds to the identifier. The data message is split into a plurality of message portions and the message portions are transmitted from the first unit to the second unit. The message portions are received at the second unit. Control data from the message portions is assembled to form a control message at the second unit. The identifier portion of the control message is compared with the identifier assigned to the second unit. When the identifier portion of the control message matches the identifier assigned to the second unit, the second unit enters an in-synchronization state. When the identifier portion of the control message is different from the identifier assigned to the second unit, the second unit enters an out-synchronization state. At least one prior control message is searched for the identifier assigned to the second unit when the second unit is in the out-synchronization state. A matching identifier is synchronized with when the matching identifier is found in the prior control messages. When the prior control messages are free of the identifier, the second unit resynchronizes with the first unit.
