摘要： An information handling system has the capability of securing serial console redirection via serial-over-LAN (SOL) by using a baseboard management controller (BMC) and a baseboard serial controller. The BMC may be coupled to the baseboard serial controller over a DCD and/or GPIO bus. De-assertion of the data carriage detect (DCD) signal from the BMC to the baseboard serial controller may cause the OS console to logout the user session. If the BMC does not support a DCD signal then a general purpose input-output (GPIO) signal from the BMC may be used instead. Most operating system (OS) consoles will logout a user session when a de-asserted DCD (or GPIO) signal is detected.

摘要： A system and method is disclosed in which the buses and physical characteristics of a server computer are monitored through server management software. A data structure for a monitored characteristic or group of characteristics is created and stored in a repository of data structures for other monitored devices and attributes within the server computer. As events, such as failure and pre-failure events, occur on one or more of the monitored attributes, the event is recorded in an event log. Using the server management software, monitoring commands can be issued by the baseboard management controller to each monitored bus to check the status of the attribute or device.

摘要： A hot insertion system for assigning system resources of a computer system to a hot inserted adapter circuit such as a device mounted on a PCI adapter card. The adapter circuit is hot inserted to the computer system via a connector such as a slot connector. Apertures of a system resource such as I/O address space, memory address space, and interrupt numbers, are reserved for each computer bus of the computer system. The devices located on the computer bus are assigned portions of each system resource aperture in a top down configuration. A system resource assignment routine finds the lowest assigned address of a system resource aperture to determine whether the aperture has enough assignable capacity for a hot inserted adapter circuit. If enough assignable capacity exists, then the system resource assignment routine assigns a portion of each system resource aperture located below lowest assigned address to the adapter circuit.

摘要： A communications system for multiple computer system management circuits to enable remote management of the computer systems via a remote management system. The management circuits are operably coupled to a remote connector circuit via a communications bus (e.g. a bus conforming to the RS-485 communications standard). The remote connector circuit can be implemented on a daughter card of one of the computer systems. The remote connector circuit includes modem circuitry for providing operating information on operating conditions of the computer systems to a remote management system and for receiving operating commands to be provided to the management circuits wherein the computer systems initiate operations (e.g. rebooting and power cycle) in response to receiving the commands. The RS-485 bus is configured in a daisy chain configuration to allow for a simplified addition of new computer systems to the bus.

摘要： A system for enabling remote console redirection on a computer system having a remote monitor connector circuit located on a different computer bus than a local monitor connector circuit. In one example, a remote monitor connector circuit located on a PCI computer bus generates system management interrupts (SMIs) via an interrupt controller to a system processor of a computer system such as a server. In response to a SMI, the system processor invokes an interrupt handler to determine the source of the interrupt. In response to determining that the SMI was generated by the remote monitor connector circuit, the system processor places the video data being provided to a local monitor connector circuit (such as a graphics accelerator conforming to the Accelerated Graphics Port interface standard) into a shared memory location accessible by both the system processor and the remote monitor connector circuit. The remote monitor connector circuit provides the video data to a remote monitor via e.g. a telephone network for display on the remote monitor. The remote monitor connector circuit generates the SMIs periodically during a startup routine until a graphical mode operating system boots up.
