TL;DR: In this article, a system and method for automatically assigning addresses to agents on a system management bus in a computer system without requiring user intervention is presented, i.e., without requiring the user to manually or programmatically set physical or logical switches.
Abstract: A system and method for automatically assigning addresses to agents on a system management bus in a computer system without requiring user intervention, i.e., without requiring the user to manually or programmatically set physical or logical switches. The computer system includes a system management bus which preferably uses the I 2 C serial protocol. The bus includes at least one SMB master and a plurality of slaves for performing desired monitoring and control functions in the computer system. According to the present invention, the SMB master assigns unique addresses to each of the SMB slaves automatically and without user intervention. This provides a simpler, more efficient, and less error prone method for assigning addresses to SMB agents. In addition, the system of the present invention automatically assigns unique addresses to new devices inserted on the bus while the bus is operating and thus allows for hot pluggable devices.
TL;DR: In this article, a fault tolerant system management bus architecture for a networking chassis includes a primary path for transmission of system management information and a secondary path to relay the information in the event of failure of the primary path.
Abstract: A fault tolerant system management bus architecture for a networking chassis includes a primary path for transmission of system management information and a secondary path for transmission of system management information in the event of failure of the primary path. The primary path includes a first microprocessor controller, coupled between the first system management bus and the processor located on a networking module. The secondary path for transmission of system management information includes a second microprocessor controller system and a dual-port memory. The second microprocessor control system is coupled to the second system management bus and to the dual-port memory. The dual-port memory is also coupled to the processor located on the networking module. The dual-port memory provides the interface between the CPU in the networking module and the second microprocessor control system, thus providing isolation and allowing the memory to be accessible by either processor. Environmental information and module identification information are stored in the dual-port memory. In the event of failure of the primary transmission path, the environmental information and module identification information can be accessed and transmitted over the backup transmission path.
TL;DR: In this article, a system and method for determining power supply requirements for a plurality of servers in an information network that includes a system management bus coupled to provide information on power being utilized by the servers during operation is presented.
Abstract: A system and method for determining power supply requirements for a plurality of servers in an information network that includes a system management bus coupled to provide information on power being utilized by the servers during operation. The information from the system management bus is provided to program instructions that provide power usage values indicative of the power being utilized by the servers, determine the maximum value of the power usage values, and determine power supply requirements based on the maximum power usage. The power supply requirements include operating power and/or redundant power requirements. A warning signal is generated if adequate power is not available to the servers.

Abstract: A system and method of real-time power management for use in computer systems. The system utilization is assessed by a North bridge, and a result is transferred to a South bridge. Thereafter, through transmitting sideband signals to a voltage controller and a frequency controller by sideband pins, the North Bridge provides faster and more efficient power management performance than the system management bus (SMBUS).
