Embodiment Construction

[0021] The embodiment of the present invention realizes the test of the module by changing the connection relationship of the module interface and verifying the data.

[0022] The module and the backplane in the embodiment of the present invention include three types of module interfaces, the first type is a low-speed Complex Programmable Logic Device (Complex Programmable Logic Device, CPLD) interface, which is mainly used to determine the existence of the module; the second type is the management The information interface is usually a 100M or Gigabit Ethernet interface, which is mainly used to transmit management information; the third type is a high-speed data interface, which is mainly used for data transmission, and the transmission speed is usually above 10G / s. There are first-type and second-type module interfaces between the management module and each service module. There are the above-mentioned three types of module interfaces between the management module and each se...

Abstract

A method for testing module is disclosed in the invention to achieve the testing of the module and save testing cost. The method comprises: connecting two intraclass interfaces of the module to be tested; transmitting data through one module of the two interfaces respectively by the module to be tested; receiving data through the other module of the two interfaces by the module to be tested and judging whether the received data is the same as the transmitted data, if yes, determining that the two module interfaces are normal, otherwise, at least one of the two module interfaces is abnormal. The invention further discloses a device for carrying out the method.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and a device for testing a module. Background technique [0002] In the prior art, a module refers to standardizing the interface and size of devices with different performances but having certain functions or uses in common, and these devices are called modules. Such as figure 1 In the switch shown, numbers 1-10 mark 10 slots, among which modules have been inserted into slots 1, 3, 5, 7, and 9, while no modules exist in other slots. Users can choose appropriate modules according to their needs, and the advantage of modular equipment lies in this, which has greater flexibility and expandability, and can adapt to various needs. [0003] Modules are generally divided into management modules and business modules according to their functions. A complete modular switch requires at least one management module and one service module. But after expansion, for example, 2 ...
