The invention provides a communication management method for mid-and-high-end rack type high-capacity equipment. The communication management method includes the following steps that communication among all board cards in the mid-and-high-end rack type high-capacity equipment is determined, and the mid-and-high-end rack type high-capacity equipment is powered on and started; the mid-and-high-end rack type high-capacity equipment is powered on and operates, an out-of-band transfer protocol and an in-band transfer protocol are started, and a state machine detects the operating state of the corresponding protocol; in the stable operation process of the mid-and-high-end rack type high-capacity equipment, the out-of-band transfer protocol and the in-band transfer protocol detect each other and are switched according to the judgment conditions of the state machine. According to the communication management method for the mid-and-high-end rack type high-capacity equipment, communication and management in the distributed high-capacity equipment are effectively achieved, the problems that management message transfer is blocked, and management messages are lost are solved, and the reliability of the equipment is effectively ensured.
