Switch fault types and analysis methods

Switch fault types and analysis methods 1. Switch fault classification switch faults can generally be divided into hardware and software faults. The hardware mainly involves power supply, backplane, port, and module faults. Www.2cto.com 1. Check whether the power lamp is flashing by checking whether the power lamp is faulty. If the power lamp is off, the power module is faulty. Protection measures: the ups power supply (uninterruptible power supply) can be used to provide stable power supply, and lightning protection measures can be taken at the same time. 2. If the device fails to communicate normally after the port is changed, the port is damaged. Www.2cto.com 3. The module of the backplane Faulty Switch is inserted on the backplane. If the environment is wet, the circuit board is short-circuited by the tide, or the components are damaged due to high temperature, lightning, and other factors, the circuit board will not work properly. For example, if the heat dissipation performance is poor or the ambient temperature is too high, the temperature in the machine increases and the components are burned out. When the external power supply is normal, if the internal modules of the switch cannot work normally, the backboard may be broken. In this case, even the electrical maintenance engineer may not be able to handle this problem, the only way is to change. Conclusion: from the above several hardware faults, poor data center environments can easily lead to various hardware faults, so when we build data centers, we must first build the anti-ray grounding and power supply, indoor temperature, indoor humidity, anti-electromagnetic interference, anti-static and other environments to provide a good environment for the normal operation of network equipment.
