Background

When an abnormal crash condition occurs in the IT equipment such as a switch, a firewall and the like during the operation process due to various reasons such as software bug, hardware component abnormality and the like, under the condition:

1) important log information can be output on a console port to facilitate fault location, and the log information can be recorded only by connecting the console to a terminal;

2) there is a certain probability that there is no output information in the console, but exception information is fed back to some pins of the processor.

In a laboratory, information can be acquired by connecting a terminal and adopting an oscilloscope to measure pins, but in an actual use scene of a user:

11) most users do not have the condition of connecting terminals, so that key log information cannot be collected;

12) the user site does not have the condition of connecting an oscilloscope to detect the state of the abnormal pin;

the device generally has a watchdog mechanism in the field operation of a user, can reset immediately after a fault, and can be damaged immediately after the field is reset, so that the problem that quick positioning is difficult after the fault occurs is solved;

the current technology monitors the output of this console through a connection terminal or a BMC of an out-of-band management processor, and some technologies also use programmable logic to store abnormal information, but this method has the following defects:

A. the BMC monitoring, which is connected to the terminal or through the out-of-band management processor, adds extra cost, and cannot record the state of an abnormal pin;
