Recovery can be easy or it can be difficult. Power hits can be fairly easily mitigated if you have decent surge protection and UPS. Working with 1000 customers who refused to turn off their computers and unplug them every afternoon when we had a thunderstorm got us pretty good with surge protection. Most of that knowledge world wide came from Florida. The only recent hardware failuresI could attribute to powerline are a gfi outlet and a device that had some operational issues even after a factory reset and reconfiguration. The only surge protection we have is built into the mains panel. Most of my devices are inexpensive and easily replaceable. I can't justify the cost of individual surge protectors. Surge protection goes farther than simply plugging in a few protectors. For most of the country, that may work for you but we get an ass kicking thunderstorm just about every day for half the year. Our biggest problems in the 80's was Colorado. Lots of lighting, and the disk controller we had had a **** power supply. Pass transistors that passed ever line glitch through. We never really had a problem in the computer room. It was always cash registers, ATMs and remote terminals that got fried. Pretty much anything with a wire coming in from outside or long unprotected wires in the building. Motels, mall stores with multiple locations in the mall and terminals running between buildings were the worst. We lost Macy's California Point of Sale terminals to IBM because your sales guy was smarter. Our sales guy tole Macy's that the data lines had to go via conduit because of the fluorescent lights. IBM guy said their did not need conduit. He knew the fire department required conduit. Smarter. |
