In fact, in theory, this kind of fault does not belong to the fault of the switch itself, but in practical application, cable failure often causes the switch system or port to not work properly, so this kind of fault is also classified as the switch hardware fault. على سبيل المثال, the connector is not tight, the order of cable production is wrong or not standardized, the cable connection should use a cross line but a direct connection, the two optical fibers in the cable are interleaved, and the faulty line connection leads to a network loop. From the above several hardware failures, the poor environment of the computer room can easily lead to various hardware failures, so when we build the computer room, we must first do a good job of lightning protection 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.
