  • Patent number: 10657080
    Abstract: A system and method for insuring efficiency of a serial link between a host server and a switch is disclosed. A fabric switch has upstream ports associated with a serial link. A fabric controller is coupled to the switch. A host server includes a BIOS and a management controller. The host server has ports coupled to the serial link ports via cables to form lanes of the serial link. A memory is accessible by the controller and the management controller. The management controller reads an expected speed and width of the serial link from the memory. The BIOS determines an actual speed and width of the serial link. The management controller sends an error message if the actual speed and width do not match the expected speed and width.

  • Patent number: 7519069
    Abstract: An IP address updating system and related method is applied to a network server having a management controller for the management controller to update IP installation information. The system includes an acquiring module, a comparing module and an updating module. The method first detects MACs of NICs attached to the network server and LAN channels of the management controller, and then compares the MACs of the NICs with the MACs of the LAN channels. When a MAC of one of the NICs is matched with a MAC of one of the LAN channels, installation fields of the matched LAN channel are updated with IP installation information of the matched NIC. Therefore, a system manager needs not to update the IP address time after time any more, and the network server has better efficiency of management.

    Abstract: An automatically setting method and related system for a network communications system having a remote console is disclosed. The method provides a network serving equipment having a management controller, and connects a network serving equipment through the network communications system to the remote console. The method sets the network serving equipment in a PXE mode, and sends request instructions to request IP address to the remote console after the network serving equipment is actuated, to acquire corresponding IP address. The network serving equipment sends IP request instructions to the remote console to request corresponding network parameter setting program. Then the network serving equipment executes the network parameter setting program instruction, and sets IP address parameters of the management controller according to the acquired IP address accordingly.

  • Patent number: 7370038
    Abstract: A stereographic network monitoring system is provided to display a stereographic representation of an abnormal unit in a controlled device monitored via a network, wherein the stereographic representation shows the abnormal unit and its relative position, so that a supervisor can be clearly informed the relative position of the component inside the controlled device and promptly take appropriate measures to remedy. This system includes a monitoring server, a database, at least a controlled device, a network unit and a display unit. The monitoring server is connected to the database and controlled device via the network unit. When the controlled device sends an abnormal message to the monitoring server, it can retrieve the device stereogram and basic data of the unit components of the controlled device for display in the displaying unit.

  • Publication number: 20070234032
    Abstract: A system and method for chassis management is proposed. The chassis management system includes at least one server unit, a first control unit, a second control unit, and a system management bus. The system management bus connects the first control unit and the second control unit to the server unit, so as to enable the first control unit and the second control unit to manage operating conditions of the server unit. One of the first control unit and the second control unit sends a request to search for a master controller. If, within a predetermined period of time the system management bus fails to indicate a master controller address on the system management bus in response to the request, then one of the first control unit and the second control unit is configured to function as the master controller, conversely one of the first control unit and the second control unit is configured to function as the slave controller.

  • Publication number: 20060228223
    Abstract: A system and a method for control of fan rotational speed are applied in an electronic device with a fan for temperature adjustment. The electronic device at least records a first fan rotational speed of the fan when a temperature of the fan is higher than a predetermined temperature interval and a second fan rotational speed of the fan when the temperature of the fan is lower than the temperature interval. A fan rotational speed during operation of the fan is recorded. The electronic device detects a temperature of an exothermic object being adjusted by the fan, and outputs a temperature parameter. The electronic device determines whether the temperature parameter belongs to the temperature interval and accordingly adjusts the fan rotational speed of the fan. The system and method make change of the fan rotational speed less sensitive to oscillations in system temperature and prolong the lifetime of the fan.
