Abstract: An electronic device has a user interface to control operations of at least one Ethernet network switch in a computer device to manage networking operations of the computer device. Connecting ports provided by the Ethernet network switch are divided into one or more types; ID codes are set to correspond to the types; sequentially different ID codes are assigned to the corresponding types of ports, and the ID codes are displayed on the user interface. The connecting ports provided by the Ethernet network switch are connected to at least one server blade, at least one management module or at least one network switch, and the user interface is a text-based user interface.

Abstract: A method for updating firmware in a microprocessor in a computer system is disclosed. The microprocessor has an application memory, a load memory and a cache, and a firmware updating program and a firmware testing program are stored in the load memory. Every time the computer system is turned on, the firmware testing program checks whether the firmware is correct; if the firmware is not correct, a user interface can be used to inform the user and the firmware updating process is repeated until the firmware is updated. As a result, the firmware updating process is ensured to be complete and correct to avoid halting of the computer system due to faulty firmware.
