Embodiment Construction

[0035] In order to effectively detect the hot-swappable module during the hot-swappable process and reduce the impact on the host and other devices on the line where the hot-swappable module is located, the embodiment of the present invention provides a hot-swappable module state detection method , system, device and network equipment, before the hot-swappable module communicates with the host, the method pre-communicates with the hot-swappable module through the hot-swappable state detection device, sends a detection message to the hot-swappable module, and according to the hot-swappable The timing sequence of the signal output by each pin of the plug-in module is judged whether the output signal of each pin is normal. Only when the output signal of each pin is normal, the connection between the hot-swappable module and the host is controlled, thereby effectively reducing the impact on the host. The impact of the hot-swappable module improves the safety of other devices on the...

Abstract

The invention discloses a method, system, device and network equipment for detecting the state of a hot-plug module, which solves the problem that the existing hot-plug module causes impact to a host and other devices on lines of the hot-plug module in the hot-plug process. The method comprises the following steps: by sending a corresponding detection message to a hot-plug module, acquiring signals output by each pin after the hot-plug module processes the detection message; and according to the time sequence of the stored signals output by each pin, judging whether the time sequence of the signals output by each pin to the detection message meets all the set requirements, and controlling the hot-plug module to be connected with a central processor of the host if so. Whether the output ofeach pin is normal is judged according to the time sequence of the signals output by each pin of the hot-plug module, and the hot-plug module is controlled to be connected with the central processor of the host as long as the output of each pin is normal,, so that the impact to the host is effectively reduced, and the safety of other devices on the lines of the hot-plug module is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, system, device and network equipment for detecting the state of a hot-swappable module. Background technique [0002] The hot-swappable module has been widely used in network equipment because it can be plugged and unplugged arbitrarily when the host is powered on and working normally. form. [0003] While the hot-swappable module is convenient to use, it also brings some problems. Since the hot-swappable module is plugged and unplugged when the host is powered on and working normally, it is directly connected to the host to form a path after insertion. The line where the host is located is affected, which may cause the line where the host is located to be powered off, or cause the device on the line where it is located to burn out. In the prior art, in order to avoid the impact of the inrush current, a corresponding protection circuit is provided. When the cu...
