Abstract: A system and method of using a baseboard management controller (BMC) to detect a fault on a communication bus. The BMC is connected to and monitors the operation of the communication bus. The BMC automatically detects a communication bus hang and reports bus hang to the host. The BMC attempts to access the communication bus. If the BMC can access the communication bus, the BMC then resets all of the devices connected to the communication bus. The BMC then attempts to contact components connected to the devices. If a component is not accessible via its communication device, the BMC blocks the channel used by the component and reports that information. Once the BMC detects that the component has been removed, the BMC attempts to recover the channel via the I2C/SM bus for use by the computer network.

Abstract: A system for offloading management controller traffic includes a data port, an out-of-band port, and a leaf switch. The leaf switch includes a switch application-specific integrated circuit (ASIC) and an unmanaged chip directly connected to the switch ASIC. The switch ASIC is configured to direct data traffic to the data port and offload baseboard management controller (BMC) traffic to the unmanaged chip. The unmanaged chip is configured to direct the BMC traffic to the out-of-band port.

Abstract: The present technology provides a system and method for smartly resetting a hang device of a server system based upon a Wake-on-Lan (WoL) message and status of the hang device. The system comprises a management device, a switch, a physical layer (PHY) coupled to a network, a network interface (NIC), a monitoring device and a delay circuit. The PHY is coupled to the network to receive network packets that includes a WoL message. The monitoring device is configured to receive status information from the management device and the WoL message, and reset the management device based upon received information.

Abstract: A method of monitoring I2C bus status using a Baseboard Management Controller (BMC) and a hardware watchdog (HW) circuit is provided. The method includes detecting, using the HW circuit, a failure of an I2C bus and determining if the HW circuit can auto reset I2C devices on the I2C bus. The method also includes, if it is determined that the HW circuit can auto reset the I2C devices on the I2C bus, resetting, using the HW circuit, the I2C devices, and if it is determined that the HW circuit cannot auto reset the I2C devices on the I2C bus, reporting, using the HW circuit, detected failure to the BMC. The method further includes processing, using the BMC, the detected failure.

Abstract: A system and method for logging error data from a central processing unit on a computer system using a dedicated crash dump device, is disclosed. The central processing unit has a management engine. The central processing unit sends an error signal. The dedicated crash dump device is coupled to the central processing unit to receive the error signal. A storage device is coupled to the crash dump device. The crash dump device sends a request to the central processing unit for error data. The crash dump device receives error data from the central processing unit. The crash dump device stores the error data in the storage device.

Abstract: A computing device includes a first component comprising a magnetic field sensor with a sensing region and a second component comprising a magnetic portion. The computing device also includes a controller communicatively coupled to the magnetic field sensor. In the computing device, the second component is movable between a first position relative to the first component, and one or more second positions relative to the first component, whereby the magnetic portion is positioned in the sensing region when the sensing portion is in the first position. The magnetic field sensor is configured for generating one or more first signals in response to detecting the magnetic portion within the sensing region. The controller is configured for generating a second signal in response to the first signals indicating the second component is in the first position.
