In a method of detecting firmware using a first electronic device, the first electronic device comprises a first baseboard management controller (BMC). The first electronic device receives a first message of requiring the first electronic device from a host computer, to detect whether firmware of a second BMC of a second electronic device runs in a normal state. The electronic device sends a second message of requiring the second BMC to obtain whether firmware of the second BMC runs in the normal state. Once the second BMC dose not response to the second message in a first predetermined time period, the electronic device recovers the firmware of the second BMC using firmware of the first BMC.

Electronic device and method for detecting firmware of BMC

A centrifugal fan includes a fan frame (), and a stator () and a rotor () received in the fan frame. The fan frame includes a bottom base (), an opposite top cover () and a side wall () interconnecting the bottom base and the top cover. A first air inlet () is defined in the top cover and a second air inlet () is defined in the bottom base. The rotor includes a hub () and a plurality of blades () extending from an outer periphery of the hub. An air flow channel () is formed between an outer periphery of the blades and the side wall of the fan frame. A cylindrical wall () is formed around one of the first air inlet and the second air inlet to guide airflow from the first and second air inlets into the air flow channel and block the airflow in the air flow channel from flowing back towards the first and second air inlets.
