Abstract: A method for controlling a fan module mounted in a region of a server rack. The method is implemented by a controller unit including a RMC and a region controller that corresponds to the region, and includes: receiving by the region controller temperature data from the server; determining by the region controller whether the RMC operates in a normal state; when the determination is affirmative, transmitting by the region controller the temperature data to the RMC, and controlling by the RMC a fan speed of the fan module according to the temperature data; and when the determination is negative, controlling by the region controller the fan speed according to the temperature data received from the server.

Abstract: A method for recovering a basic input/output system (BIOS) image file of a computer system is provided. The method includes steps of: controlling a switch unit of the computer system to switch from a first state to a second state when the BIOS image file is to be updated; reading a current BIOS image file so as to store the same as a backup; controlling the switch unit to switch back to the first state; determining whether a command is received within a first predetermined time period when the BIOS image file is successfully updated to a new version of the BIOS image file; and when negative, controlling the switch unit to switch to the second state and writing the backup of the current version of the BIOS image file.

Abstract: When a baseboard management controller (BMC) is used to control a fan speed of a fan unit of a server by executing a firmware with fan parameter data stored in one temporary storage region, the fan parameter data is updated by receiving fan parameter update data and storing the fan parameter update data in another temporary storage region, and updating the fan parameter data using the fan parameter update data after determining that the received fan parameter update data is valid.

Abstract: A method for ascertaining an IP address and a MAC address of a unit under test (UUT) mounted in a rack server includes: assigning and providing an IP address to the UUT when receiving a request for an IP address which includes the MAC address of the UUT; storing the IP address thus assigned and the MAC address as a set in a mapping table; transmitting boot configuration data to the UUT when receiving a request for boot-up; determining whether the UUT is running an operating system; and designating the IP address thus assigned which corresponds to the MAC address in the mapping table as a static IP address when it is determined that the UUT is running the operating system.

Abstract: A method for controlling firmware update of a set of serially coupled expanders is implemented by a host computer. The host computer checks whether or not none of the expanders is in a condition of updating firmware. The host computer permits transmission of the firmware update file to a to-be-updated expander when the determination is affirmative.
