Procdures to protect equipment and data

Procdures to protect equipment and data

1. ESD

   • Electrostatic discharge (ESD)
   • ESD can cause permanent damage to electrical components.
   • to prevent ESD you can:
     • Keep all components in antistatic bags until you are ready to install them.
     • Use antistatic wrist straps when working on computers.
     • Use antistatic mat and place all components on the map.
     • restrict movement to slow antistatic electrisity

2. Climate

   • Climate affects computer equipment in a variety of ways:
     • If the environment temperature is too high, equipment can overheat.
     • If the humidity level is too low, the chance of ESD increases.
     • If the humidity level is too high, equipment can suffer from moisture damage.
   • make sure that the tempreture in the room is at a good level to ensure that there will be no damage to thecomputer components

3. spike

   • This is caused by a Sudden increase in voltage that lasts for a short period and exceeds 100 percent of the normal voltage on a line.
     • Spikes can be caused by lightning strikes
     • but can also occur when the electrical system comes back on after a blackout.
     • any sudden changes in electrical power
     • preventations

4. Brownout

   • Reduced voltage level of AC power that lasts for a period of time
     • how is it caused?
       • Brownouts occur when the power line voltage drops below 80
       • Overloading electrical circuits can cause a brownout.
       • this means if the voltage drops power than 80 the brownout will kik in
