Module fault processing

- May 03, 2018 -

The switch is composed of many modules , such as stacking modules , management modules ( also known as control modules ) , expansion modules , etc . These modules have a small probability of failure , but once problems arise , there is a significant economic loss . If the module is connected , there is a pair of optical interfaces . If the expansion module is an optical fiber connection , there is a pair of optical interfaces . If the expansion module is an optical fiber connection , it is necessary to check whether the cable is in the correct position , whether there is parity , whether there is a data stream control , etc . When connecting the expansion module , it is necessary to check whether the communication mode is matched , such as whether to use a full - duplex mode or a half - duplex mode .
