For some business with premises such as cafes, retail, business enterprises rely on networks, lightning loss by the loss of more than just hardware, and the suspension of business caused by the network or contact the inconvenience caused by business interruption,can not be estimated.In fact, many network has a very good idea for mine, but most corporate executives prevention awareness in this regard is not in place, that is not necessary and can not be related to preventive measures.In fact, lightning events often occur in areas such as southern and eastern China the two most provinces, whether in urban or rural, even if the router placed in the room, the probability of being struck by lightning, or pricey.In many cases coupled with lightning, often accompanied by ADSL cat, switch or other equipment is damaged, so spend several hundred dollars for prevention, is necessary.
A simple example: fiber-optic network is generally not afraid of lightning, but the metal shield is not grounded, the server room's power supply is grounded, but the power switch of each floor are not grounded, it is not installed lightning protection devices, switches,The entrance on the network has not received mine, hit by lightning over-voltage caused when the pair will be very easy to damage the equipment.
Thunder and rain, the user first, power lines pose a threat, and second, ADSL broadband lines, lightning strikes can cause induced currents on the one hand, and thus the power generated in the strong electrical pulse and surge, which led directly to the routing equipment damage.In addition, the pair also have a strong sense in the current, or even directly hit by lightning, which led directly to the router LAN interface, or even damage the router.
Lightning damage to the router
Lightning reached the LAN or WAN, the powerful energy of the energy received in the first outbreak of electronic components, we can see a charred, small components are also related to a charred, it is generally more energy, directly affected by the lightning attacks.
If less energy and therefore less likely to damage components, for the larger components can not hurt, so you can see some small parts near the charred phenomenon.
Do not see a problem with it.Since the internal circuits of electronic components is very small, so although only very minor exterior looks charred, but often within the lines have been destroyed.Even more frightening is that, in addition to the focus of the components, some components may look totally can not tell, but the internal circuit is close to destruction.
Overview of the router Lightning Protection
Said earlier, thunder and rain, on the router, power lines pose a threat to the First, Second, ADSL broadband lines, according to the 2, we take some effective lightning protection measures.
1, lightning protection hardware:
Install power mine house is very necessary, not only to prevent being struck by lightning bad router, but also for other appliances lightning effect.If the cottage, be sure to install a lightning rod, which can effectively prevent lightning strike, if it is building, to check whether a lightning rod work.Also, check whether the outdoor power lines exposed situation, whether well-insulated connectors.
Lightning protection is a very important part of earth.Currently, most computer users do not pay attention to the ground.A good grounding, static electricity and lightning can produce voltage turn away to protect the security of computer equipment.Although a lot of computer power plug is the three-grounded outlet, but the ground is usually empty, just a display.To this end, the proposed ground alone computer users, a good choice for three-phase grounded plugs, which can greatly reduce the computer when lightning strikes and ADSL broadband equipment, routers and other damage.
2, the deployment of broadband lightning protection measures:
Currently, there are already some on the market for broadband Modem mine products, users can purchase products, the suitability of the purpose of mine.Lightning protection products on the market quite a mixed bag, do not rule out some of mine under the banner of the name but not mine-protected product, the user must pay attention to the time of purchase.
In addition to ADSL Broadband Modem lightning protection products, users can purchase call mine.Lightning protection is installed in the phone splitter in front of the ADSL signal on it.Mine when to buy phone, be sure to go to regular stores to buy, but also to save the invoice, but the quality of relations if it is found, you can find businesses for damages.
Analysis of lightning processing:
1 line from the telephone line by lightning
This phenomenon is most common, accounting for 74% of the overall lightning.Happens is that lightning from the ADSL phone line to play in, first hit to the ADSL cat call to the router's WAN port, eventually leading to the components within the router is broke.Pull the phone cord from the outside, the most they hang in the air, it is easy to become a lightning hit the target, so what happens is the largest.High-voltage lightning energy, along the lines come in, damage to different devices all the way until the ground or the consumption of energy have been exhausted.
Users should start against such a lightning start, first of all should look at a nearby phone line, whether at a high place, or has outstanding objects, it is easy to become a lightning target, that this situation should be promptly carried out repair and improvement, please call Board.In addition, the need for lightning protection for the line to buy mine-terminal location of the telephone line access, to protect all internal network devices.Mine terminals can effectively offset the lightning energy, even if the offset can not be completed, at most only wounded ADSL cats, can not damage other equipment.
2, from the local area network lines by lightning
This happens less, about 21% of the overall lightning.Happens is that line from the LAN to play in, is likely to first switch broken, call to the router's LAN port, and then broke the components inside the router.This happens usually in the area or home users across the floor of a building or line out the situation exposed in this case because the network cable may be suspended, a lightning strike directly to the target; or no direct hit, but close to the metal becausewiring, such as iron pipes, railings, resulting induction, the same LAN can jump high to pressure lines.
Exposed for the LAN line users, which should also guard against lightning.First, to avoid the lines vacated through it, so easy to become a lightning target, a method is converted into wireless network bridge, or insulating pipe extension from the ground or the wall alignment.Second, the alignment is best to avoid large areas or near the metal lines, to prevent the occurrence of jumping power, the innocent are hurt.
Some of the LAN cable to lightning strikes because of lightning in the local area network wiring pipe lines by the induction occurs, which must be prepared to building ground line.To relieve Leiduan Zi, under the switch must be connected easily lightning line to protect the switches and routers.If an older building or poorly grounded, it must be all or only protect access routers, switches and routers connected to.
3 lines from the power line by lightning
This happens very rare, accounting for only a median probability of lightning, about 5%.This is because the buildings will now generally be grounded, can lightning strike away.Happens is that lightning hit came from the power outlet, the power switch part of the line broke.This damage is less damage, the latter will be introduced.As lightning strikes the line must come from the router, so opportunity small.Induction occurred more frequently come in the case of local network lines.But the power cord is also the case among some of induction.Generally higher than the old buildings, such as a lightning rod in the set will not have this situation.
This, of course, be prevented from power lines, a practice to be observed for the whole building to improve the ground situation.Another is the use of lightning in the inserted row, or to prepare the ground row inserted in order to effectively rule out the energy.After the installation of power lines is considered lightning terminal, the relative power of the lightning terminal is more expensive.
Mine is like insurance, if the first were made to avoid large losses, business site users should be considered.Users should observe the layout of the network cable line, determine whether the related initiatives.
