    Abstract: Embodiments of the present invention provide an apparatus and a method for cabinet asset management and a cabinet system. The apparatus for cabinet asset management includes a management unit and at least one antenna board unit. The management unit sends a read signal to the antenna board unit. After receiving the read signal, the antenna board unit sends the read signal in a form of an electromagnetic wave, so that after sensing a magnetic field signal, a label within a radiation range of the electromagnetic wave sends, using an induction current, configuration information of a physical component stored in the label to the antenna board unit. After receiving the configuration information, the antenna board unit reports the configuration information to the management unit. After receiving the configuration information reported by the antenna board unit, the management unit performs data analysis processing.

    Abstract: In a system for controlling a radio base station, an out-of-band emergency channel based on a power cable is established between a baseband unit (BBU) and a remote radio unit (RRU) such that even when a unique communications interface common public radio interface (CPRI) between the BBU and the RRU is abnormal, the BBU can still effectively control the RRU using the out-of-band emergency channel. In another system for controlling a radio base station, out-of-band emergency channels based on power cables are established among multiple RRUs such that even when a unique communications interface CPRI between a BBU and a target RRU is abnormal, the BBU can still effectively control the target RRU using an out-of-band emergency channel between any RRU (a unique communications interface CPRI of the RRU is normal) and the target RRU, and the BBU can effectively control the RRU.
