摘要:
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.

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.

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.

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.

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.

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.

In accordance with embodiments of the present disclosure, an information handling system may include a processor and an access controller communicatively coupled to the processor. The access controller may include a memory having a bootloader portion including a first memory address and a second memory address a second processor communicatively coupled to the memory. The second processor may be configured to: (i) attempt to execute the a first copy of a bootloader stored at the first memory address; (ii) in the event of a failure to execute the first copy of the bootloader, copy a second copy of the bootloader stored at the second memory address to the first memory address; and (iii) subsequent to copying the second copy to the first memory address, attempt to execute the second copy of the bootloader stored at the first memory address.

A telecommunications system includes a wireless telephone (14) and a personal computer (18) having a wireless telephone interface (24). The wireless telephone (14) is equipped with a personal computer (PC) function key (22) for activating PC controlled functionality. More particularly, when the PC function key (22) is activated, the wireless telephone (14) signals the PC it is ready to receive PC controlled functions. Thus, a menu of options may be transmitted from the PC (18) to the wireless telephone. The user clicks the desired selection to activate or interact with the corresponding program on the personal computer (18).
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.
