Abstract

The invention discloses a hot plug testing device and method, wherein hot plug testing device is set between a hot plug device and a commutator, and correspondingly connects the signal line between the commutator and the hot plug device. The hot plug testing device comprises a power module for providing power form a control module; a control module for sending a switch control command to a switchmodule based on the received control command; a switch module for realizing the disconnection or connection of at least one signal line between the commutator and the hot plug testing device, whereinthe at least one signal line is selected from a LinkOk signal line, a Present signal line, a VCC signal line and a GND signal line. The device solves the problem that it is impossible to test the hotplug of the management plate / line card in an automatic testing.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a hot-swapping test device and method applied to the hot-swapping test of a management board / line card. Background technique [0002] With the rapid expansion of network scale and application fields, the network has increasingly become an indispensable part of social life, and the communication and exchange between enterprises and individuals cannot be separated from the use of the network. With the increasing dependence of enterprises on the network, the security and reliability of the network are becoming more and more important. Once the network service is unavailable, it may seriously affect the productivity and profit of the enterprise. The best way to increase network reliability is to reduce the occurrence of sporadic downtime and reduce recovery time (MTTR) after a failure. Hot-swap technology is one way to improve product reliability. [0003] Hot-plugging (Hot-pluggin...
