Each module of switching equipment of backboard breakdown   are to receive those who be inserted on backboard. If the environment is damp, short circuit of circuit board be affected with damp be affected with damp, or yuan because of the element such as high temperature, be struck by lightning damage of parts of an apparatus can cause circuit board cannot work normally. For instance: Medicinal powder hot property bad or environmental temperature brings about the temperature inside machine too high to lift, cause yuan of parts of an apparatus to burn out. In exterior power source the circumstance of normal power supply falls, if each in-house module of switching equipment cannot work normally, that may be backboard bad, encounter this kind of situation even if electric equipment maintains an engineer, be afraid also at the end of one's wits, the method of only changes namely backboard.   of wire cable breakdown actually this kind of breakdown from theoretic tell, do not attribute the breakdown of switching equipment itself, but in be being used actually, cable breakdown often causes switching equipment system or port cannot work normally, so here also breakdown of hardware of switching equipment of classify of this kind of breakdown. For instance contact is received insert incompact, the order when wire cable is made arranges a mistake non-standard perhaps, when wire cable joins, should use however with alternate line connect a line continuously, two in cable fiber-optic crisscross join, wrong circuit join brings about network annulus road to wait. From the point of the breakdown of a few kinds of hardware above, computer room environment not beautiful causes all sorts of hardware trouble extremely easily, when so we are constructing a computer room, must have done the ground connection that prevent thunder and power supply source, indoor temperature, indoor humidity first, prevent electromagnetism interference, antistatic the construction that waits for an environment, the regular job that is network equipment provides favorable environment. System of switching equipment of systematic error   is the combinative put oneself in another's position of hardware and software. There is in switching equipment interior but of refresh read-only memory, what it saves is the software system with this switching equipment indispensible place. This kind of mistake also is mixed our common Windows, Linux is same, as a result of the matter that designs at that time, put in a few flaw, when the condition is appropriate, can bring about switching equipment to be fully loaded with, the happening that loses the case such as bag, complex package. So switching equipment system offerred such as to the means such as Web, FTP will download and replace a system. Be in of course upgrade when the system, produce a mistake likely also. To this kind of problem, we need nurturance to often browse the habit of equipment manufacturer website, if new system rolls out new perhaps patch, update in time please. Configure undeserved   abecedarian to not be familiar with switching equipment, perhaps configure as a result of all sorts of switching equipment different, the member that administer often can appear when configuring switching equipment configuration is wrong. For instance VLAN differentiates incorrect bring about a network to be illogical, port is shut erroneously, switching equipment and the mode configuration that the net blocks do not match wait for a reason. This kind of breakdown discovers very hard sometimes, need certain experience to accumulate. If cannot ensure the configuration of the user has a problem, restore to give factory acquiesce to configure first please, next configuration of another pace ground. Had better be before configuration, read a manual first, this also is one of habits that net canal wants nurturance. Every switching equipment has specific installation manual, user manual, have to every kinds of module deep explain specificly. Because the brochure of a lot of switching equipment is written with English, the redo after the user with so bad English can seek advice to the engineer of supply business is specific configuration. Exterior element   because virus or the existence of the circumstance such as hacker attack, likely some lead plane sends a large number of notting agree with to add up to the data that encloses regulation to wrap to place connective port, it is beyond the mark to cause switching equipment processor busy, cause data bag to have not enough time transmit, bring about buffer excessive to give generation to lose packet of phenomenon then. Still having a kind of case is broadcast storm, it can take up not only many network bandwidth, and still will take up many CPU handles time. If the network is long be taken up by bag of data of much be on the air, nod pair of communication normally cannot on the rails, network speed can slow or break down. A net gets stuck or a port malfunctions, cause broadcast storm likely. Because switching equipment can break up conflict region only, and impartible broadcast region (differentiating below the circumstance of VLAN) , occupy communication gross when the measure that broadcast includes so 30% when, the transmission efficiency of the network can drop apparently. Summary: Because phenomenon of switching equipment breakdown is varied, eliminate step without what secure, and some breakdown often are had those who make clear is directional, can identify reach. So can according to particular case concrete analysis, no matter be what kind of breakdown,difficult issue is for the member that new to network is administered of course, if you hope,can make switching equipment trouble so eliminate ace, must accumulate experience in routine, every do well a problem is absorption go reviewing problem germ and means of settlement. Such ability complete the work that the network administers better.
