Preparation At The It Information Tech Dept Saves Electronic Failure
There once was a foolish company owner who while demanding that his computer system
with it highly private and confidential government information could go nowhere near the internet plugged his computer network intoa computer fax machine ,attached to a DSL line. Its all for convenience he demanded. I only plug in the line for a minute.
Why does this time bring so much trouble? On top of that massive summer storms are foretold by excessive temperatures.The heat surges in turn cause massive amounts of people to turn on their energy robbing air conditioners in one short brief time period. It is not unlike a million people in New York City all leaving their TV at commercial break time , when the ads come on the tube , going to the washroom and reducing the city water supply pressure in one brief snap. All this increased used of power in one jolt can either lead to brownouts , power sags and immediate surges on the line when those units power up , cool their areas and their thermostats place these air conditioners units back into their hibernation or rest modes - where they use minimal power. It's one dangerous situation and a disaster in the wings for an areas computer and electronic systems. As more and more people use these appliances, power utilities adjust their voltage output, sometimes causing erratic power sags and spikes, which are extremely dangerous for computer hardware as well as software. Power utilities also tend to become more conservative to avoid another outage like that which happened in the hot August summer of 2003.
Its not only storms such as tornadoes which cause ac power line abnormalities.In the rest of the world add in tsunami's earth quakes and even powerful winter storms up north in Canada disrupting hydro power lines and whole electric grid systems leading to surges and tweaks on conditioned power lines.Add in even the threat of terrorist attacks on power installations and you have a quagmire and environmental disasters in the offing. The unique geography of the U.S. Listen to the Coast to Coast Radio Show with host Art Bell , and you will learn that massive storms and floods are on the greatest increases of all.Its as if the end of the world is coming - soon. Tornadoes by their very nature are highly unpredictable even with the latest weather monitoring technologies.
Powerful storms be they tsunamis , hurricanes or even winter blizzards north from Canada can all do the similar power grid serious blips and bleeps. Most affected are the utility lines usually leading to lengthy unexpected blackouts?
As well last years hurricane season was a record breaker with a barrage of named storms, causing the National Hurricane Center to resort to the Greek Alphabet ever. It was also the first season since 1851 to have three categories of five storms. (Katrina, Rita, Wilma).
Tornadoes are accompanied with thunder and lightning. Lighting can cause serious damage on electrical appliances and computers in particular. With each flash containing about 1 billion volts and between 10 and 20 thousand amps of current and an ability to transfer through wiring or plumbing it has the potential to destroy everything in its path, of course including your irreplaceable Computer and Software Collection.
Everyone is at risk. The National Oceanic and Atmospheric Administration (NOAAA) reports and average of 20 million clouds to ground flashes have been detected every year since 1989.
However, not all is grim. These times present excellent opportunities to employ protective devices in order to secure you.
It is important first of all to purchase a proper surge protection device and have it fully installed. These are in various types;
a) Power bars with a simple switch. These are widely used thanks to their availability and affordability. However the switch is just that, a switch, not a surge protector. They hardly offer any protection to your devices.
b)Simple Surge Protection devices. These are better than the switches but though slightly effective, are limited by the fact that the surge protection is afforded by simple Silica sand. With time and moisture (usually no more than a year) the surge protection is highly diminished, exposing you to risk, mostly without your knowledge. Uninterrupted backup power devices differ not so much in their electronics but by the capacity of their internal lead acid battery. More expensive deices have a larger and heavier battery.You can usually judge this by simple heaviness, size and bulk.Surge protection devices can be usually be judged by the costliness of the product line. Better devices have electronic components and switches.They are more costly to buy , often not on sale pricesand offer substantial relief insurance promises.The levels of capacity of protection. measured in terms of joules or watts should be clearly labeled on the retail package and stamped on the underside , or top-side of the device as well. Remember again that you must replace them every year.
APC uninterrupted power units. There are no shortage of brands or models available. Uninterrupted power supplies utilize an integral built in battery. The batteries are the old solid types - acid and lead.These are the types of batteries which are used solidly in automobiles.
You can always count on your car battery , as long as it in good condition to start up your car , spring ,winter , summer or fall.They hold a lot of power and they hold it for a long time. As your APC unit is plugged into the ac socket in your wall , the unit silently and slowly charges. The lead batteries in these APC units are relatively heavy due to the dense and solid nature of their lead metal components.What makes the difference in APC units and their price variations are the size ,weight and thus expense of the batteries used.Lead acid batteries are relatively expensive both to make , purchase and heavy to ship. The more capacity you need , the heavier and larger the unit and more expensive as well. Choose the capacity of power storage that you feel you need and recquire. The main difference in the cost of these units is not the model line but rather the size and expense of the internal lead acid battery of the APC electrical power storage and safetyunits. These are more expensive and far much better than the two mentioned above. They can serve for a longer period depending on specifications. Make sure that it is rated well above peak power use not lower power use.
d) Uninterrupted Power Supply (UPS). It is a device which maintains a continuous supply of electric power to connected equipment by supplying power from a battery when utility power is not available. Typically most UPC ( uninterrupted power supply( units and systems have two rows of plug ins. One will be marked "Uninterrupted Power Supply" , the other "Basic Surge Protection".The distinction is most important.The surge protection affords good surge protection against power-line surges.The UPS function will run the plugged in units off the internal battery of the UPC or APC.Critical components as well as the most essential electonic components should and must be run off these settings.Less essential components not.Why are not all rows of plug-ins linked to the interior battery . There is a simple answer.If all plugs were battery supported a much larger and costly battery would be required unnecessarily.As well the power run time would be reduced for no real good reason or use.Its more efficient and cost effective in this manner.Its all good and proper product planning and consolidation of effect and efforts. When a power failure or abnormality occurs, the UPS will effectively switch from utility power to battery power keeping your appliance safe from surges and possible damage. While they are not limited to any particular type of equipment, they are typically used to protect computers. When installing this valuable backup component - the uninterrupted battery backup supply , in your computer network go the extra step and install the included powered shut down software system onto the controlling pc. If software has been lost of simply misplaced it can easily be downloaded from the manufacturers website. Most vendors include versions of the automated safe shutdown programs for a variety of popular operating systems including Windows NT, 2000 , Microsoft Server 2000, 2003 , 2007, Microsoft Vista products , The Mac OS 7,8,9 and X operating system as well as the various distributions and distros the Linux and Unix operating systems.As well you should find included in the APC retail carton a USB plug in device to connect the UPC uninterrupted power supply unit to the UPC power control master computer to afford a simple yet coordinated computer networks shutdown. All in all to spend less initially , and think that the purchaser cheated the tax man up front or the gods of chance is poor economy overall.
You don't have to wait suffer when that tornado or that summer heat comes. Plan ahead to prevent all threats of disaster and inconvenience to your computer systems.
