Troubleshooting Process of Industrial Switch We Should Follow

Industrial Switch is also called industrial Ethernet switch, that is, Ethernet communication equipment applied to industrial Internet and industrial digital intelligent control field. Because of the standard TCP/IP network, it has good openness, wide application, high performance and high reliability, Ethernet communication technology has become the main communication standard in industrial control field.

Industrial switches are mainly used in electric power, factory automation, coal mine automation technology, urban rail, wind power generation and other industries, followed by metallurgical industry, crude oil and petrochemical industry, road traffic control automation technology, fully automatic house control system, oil and gas field control automation technology, hydropower plant control automation technology, machine room monitoring system software, water conservancy project supervision, Environmental protection supervision and other industrial automation fully automatic sites.

With the continuous expansion of the application field of the industrial switch, the industrial switch encounters various fault conditions. If there is no definite troubleshooting process, it will waste a lot of manpower, material resources and time, and even cause safety accidents. Therefore, in order to better provide evidence for troubleshooting, we can conduct in-depth analysis according to the following standards and details when analyzing the failures of industrial switches:

1. From far to near

Port control module ->leveling cable ->leaky line ->a line， like the switch, check one by one, and remove the remote fault first.

2. From outside to inside

If there is a fault in the industrial switch, we can first identify it from various external display lights, and then check whether there is a problem with the corresponding components inside according to the fault signs. For example, the POWER LED signal light indicates that the power supply is normal. If it is off, it indicates that there is no power supply; LINK LEDs are light yellow, indicating that the connection is currently working at 10Mb/s; emerald green indicates that it is 100 Mb/s; when it is off, it indicates that there is no connection; when it flashes, it indicates that the port is manually closed by the administrator; RDP LED indicates redundant power supply; MGMT LED indicates the manager control module. Regardless of whether the fault can be determined from the outside, it is necessary to log in to the industrial switch to determine the actual fault and implement the corresponding troubleshooting countermeasures.

3. From soft to hard

No one wants to take a screwdriver to dismantle the industrial switch for no reason before talking about the failure of the industrial switch. Therefore, during the inspection, the system settings or systems are always checked first. If the mobile phone software cannot be solved, it is the hardware configuration. For example, if a port is not easy to use, we can first check whether the port to which the user is connected is not in the corresponding VLAN, or whether the port is turned off by another administrator, or for other reasons. If you eliminate many possibilities in the operating system and configuration, you can probably guess the real problem - hardware configuration failure.

4. Target

When encountering complicated industrial switch faults, it is necessary to first eliminate them from simple practical operation. If the problem cannot be solved, consult a professional engineer. This can speed up troubleshooting and improve work efficiency.

Following the above troubleshooting process of industrial switch, we can improve efficiency, effectively save labor resources, avoid waste of people and property, and avoid some safety production problems.
