Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0030] Such as figure 1 As shown, the device for simulating hot plugging of interface cards includes a mother card and an interface card for data communication with the mother card through a data bus. The mother card includes a processor CPU and a hot-swappable analog module, such as a CPLD (Complex Programmable Logic Device, a complex programmable logic device), and the hot-swappable analog module is connected to the interface card through a power supply enable signal line; The data bus is connected to the interface card; among them, the CPLD is used to judge the type of the data bus between the mother card and the interface card. ; When the data bus does not support violent hot swapping, after the processor loads the driver program of the interface c...

Abstract

The invention provides a device and a method for simulating interface card hot-plugging. A hot-plugging analog module arranged on a master card is used for timing control of on and off of an interface card, in-place signals when the hot-plugging analog module is in physical hot plugging-in and interrupt signal change when the hot-plugging analog module is in physical hot pulling-out, so that physical hot plugging of the analog interface card is completed, the problem that equipment is easily damaged due to manual repeated physical hot plugging in a physical hot plugging test of a system is avoided, and the problem of extremely high workload on development and test links is solved.

Description

technical field [0001] The invention relates to the technical field of communication equipment testing, in particular to a device and method for simulating hot plugging of interface cards. Background technique [0002] With the rapid expansion of the network scale and application fields, people's dependence on the network is increasing, and the security and reliability of the network are becoming more and more important. Once the network service is unavailable, the loss that may be caused is immeasurable. The best way to increase network reliability is to reduce the occurrence of occasional downtime and reduce recovery time (MTTR) after a failure is dealt with. Hot-swap technology is one way to improve product reliability. [0003] Hot-plugging (Hot-plugging or Hot Swap) refers to allowing users to take out and replace damaged boards without shutting down the system or cutting off the power supply, thereby improving the system's ability to recover from disasters in a timely...
