Abstract: 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.

Abstract: Systems and methods for providing instant-on functionality on an embedded controller are disclosed. A method of providing instant-on functionality on a controller comprises an initial state, an intermediate state and a final state. The initial state comprises installing a first responder code, enabling the first responder code and enabling a timer interrupt service routine. The intermediate state comprises registering the first responder code as a timer interrupt service routine. The timer interrupt service routine initiates periodic processing. The final state comprises registering a steady-state interrupt service routine.

Abstract: Communications between a host information handling system and its management controller sent through a shared LOM are re-directed at the LOM from communication through a network to instead communicate directly between the host information handling system and management controller. A management module compares destination addresses of packets sent from the host information handling system and the management controller with host information handling system and management controller network addresses stored on the LOM. Packets having destination address that match a host information handling system or management controller network address are redirected from communication across the network to communicate directly between the host information handling system and management controller.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An information handling system receives management information from a network, such as IPMI information, with plural network interface cards of the information handling system in a teaming configuration. Upon detecting management information, a network interface card issues an SMBus alert to a management processor of the information handling system. A team module running on the management processor reads the status of the network interfaces to identify the network interface associated with the alert and reads the management information from the network interface. Management information sent to the network is sent through a predetermined one of the network interfaces to ensure that, if teaming gets deactivated at the switch, there will not be multiple NICs with the same BMC MAC address transmitting to the switch.

Abstract: An information handling system has the capability of matching UART baud rates and other serial data parameters between a system UART and baseboard management controller (BMC) UART used for serial-over-LAN (SOL) access to the information handling system via an Ethernet connection, either locally or remotely by a user, administrator, maintenance technician, etc. The BMC may snoop set-up data sent to the control register(s) of the system UART, look up a corresponding baud rate from a baud rate table of the BMC and set the BMC UART to match the system UART baud rate and other serial data parameters so that SOL access to the information handling system is available no matter what baud rate and/or serial data parameters an application may have programmed the system UART configuration registers. The BMC may snoop system UART data over a simple data bus such a low pin count (LPC) bus.

Abstract: An application programming interface (API) enables a telephone to utilize the hardware resources of a computer that is connected to the telephone in a master/slave relationship that causes the computer to function in the manner of a peripheral to the telephone. Specifically, the telephone attached to the computer can utilize the relatively large memory capacity of the attached computer to store excess telephone-specific data and can utilize the relatively high sophistication of the processing capability of the connected computer to perform intensive data processing operations. The API allows the functionality of the telephone to be extended without requiring a telephony-equipped computer.
