Abstract: A port status synchronization method, related device, and system, where a physical layer (PHY) device or an external processor connected to the PHY device determines whether a first service interface of the PHY device changes, and when the first service interface changes, controls a second service interface of the PHY device to restart auto-negotiation and sends, using the second service interface, an auto-negotiation advertisement packet to a first device connected to the second service interface in order to trigger the first device to synchronize, according to the auto-negotiation advertisement packet, a status of the second service interface and a status of the first service interface such that performing port status negotiation and synchronization between a link layer (media access control (MAC)) device or the first device and the PHY device using a service interface is achieved, without a need of disposing a management data input/output (MDIO) interface.
Abstract translation: 端口状态同步方法，相关设备和系统，其中连接到PHY设备的物理层（PHY）设备或外部处理器确定PHY设备的第一服务接口是否改变，并且当第一服务接口改变时，控制 所述PHY设备的第二服务接口重新开始自动协商，并且使用所述第二服务接口向连接到所述第二服务接口的第一设备发送自动协商广告包，以便触发所述第一设备同步，根据 自动协商广告包，第二服务接口的状态和第一服务接口的状态，使得在链路层（媒体访问控制（MAC））设备或第一设备和PHY之间执行端口状态协商和同步 实现了使用服务接口的设备，而不需要配置管理数据输入/输出（MDIO）接口。

Abstract: A method, apparatus and storage medium for starting up peripheral component interconnect express (PCIE) device are provided. According to the method, a basic input/output system (BIOS) attempts to verify firmware of a PCIE device to determine whether the firmware of the PCIE device is tampered with. Moreover, the BIOS may only start up a PCIE device with firmware that succeeds in the verification. Therefore, a computer device is prevented from starting up a PCIE device with firmware that is tampered with, thereby reducing the security risk caused by the PCIE device to the computer device.

Abstract: A connector (100) and a communications device is disclosed. The connector includes a connector body (41) and three connecting ends disposed on the connector body. M signal interfaces (51a) inside a first connecting end (42) are in communication with M signal interfaces (51b) inside a second connecting end (43) in a one-to-one correspondence. The first connecting end is connected to a backplane connector (32) on a backplane (31). The second connecting end is connected to one end (45a) of a transmission cable (45), and the other end (45b) of the transmission cable is connected to a communications component (46) on a target board (33a). The backplane is configured to implement communication between X boards (33), and the target board is any one of X boards, where M≥1 and X≥1. A third connecting end (44) is configured to secure the connector body to the target board.
