Problems solved by technology

[0004] 1. When using a blade server to perform functional tests on the PCI-E expansion backplane, there are a large number of human-computer interaction testing tasks, which is not only inefficient, but also often results in test failures due to errors in human judgment.
[0005] 2. When using a blade server to test the function of the PCI-E expansion backplane, it is necessary to cooperate with the startup of the blade server, which will lengthen the test time of the PCI-E expansion backplane, thereby affecting the production cost and product quality
[0006] 3. When using a blade server to test the function of the PCI-E expansion backplane, since the blade server is quite expensive, it is necessary to obtain an additional blade server for testing, which will increase the cost of hardware acquisition

Embodiment Construction

[0033] The following will clearly illustrate the spirit of the present invention with the accompanying drawings and detailed descriptions. After those skilled in the art understand the embodiments of the present invention, they can be changed and modified by the techniques taught in the present invention without departing from the present invention. spirit and scope.

[0034] Traditionally, when performing a functional test on a passive backplane (such as a high-speed peripheral component contacting an expansion backplane, later called a PCI-E expansion backplane), an active computer (active device, such as a blade server) is required to conduct a functional test at the same time. , the passive backplane can be tested only after the blade server wakes up the passive backplane after starting up and provides a suitable working environment for the passive backplane to know whether the passive backplane is qualified.

[0035] Such as figure 1 as shown, figure 1 A schematic block...

Abstract

The invention relates to a passive back plane testing module and a passive back plane testing method thereof. The testing module comprises a circuit board and a micro-processing unit, wherein the testing module is electrically connected with a passive back plane and a monitoring device respectively; and the micro-processing unit is positioned on the circuit board and electrically connected with the passive back plane and the monitoring device, and when testing the passive back plane, supplies power to the passive back plane by a general purpose input / output interface, initializes the passive back plane by a programmed input / output interface, tests the passive back plane by a system management bus interface and feeds a testing result back to the monitoring device.

Description

technical field [0001] The invention relates to a test module, in particular to a test module for a passive backplane and a method for testing the passive backplane. Background technique [0002] Since the high-speed peripheral component interconnection (Peripheral Component Interconnect Express, PCIExpress later referred to as PCI-E) expansion backplane is a passive component, it needs an external power supply and a start signal before it can be initialized to work. Therefore, the traditional PCI-E expansion The function test of the backplane (raiser card) must be carried out with a blade server at the same time, so that after the PCI-E expansion backplane is connected to the blade server, it can be woken up by the blade server after it is turned on. The blade server will test the power supply, signal and protocol functions of the PCI-E expansion backplane to know whether the PCI-E expansion backplane is qualified. [0003] However, when the blade server is used to perform...
