Study Notes
- Material Safety Data Sheets (MSDS) provide proper disposal information for components.
- MSDS is required by the United States Department of Labor Occupational Safety and Health Administration (OSHA).
- MSDS may also be referred to as Safety Data Sheets (SDS) in other parts of the world.
- MSDS provides documentation on how to properly dispose of hazardous chemicals in batteries, display devices, toner cartridges, and more.
- Batteries used in laptops and UPSs are hazardous waste and should be disposed of properly.
- Toner cartridges often have recycling programs with return labels for sending back used cartridges.
- Always reference the MSDS to ensure proper disposal of components if unsure.
Ideal Environment Considerations
- Computing devices constantly create heat, so they should be in a cooled environment.
- High humidity can cause condensation and problems with electronic devices.
- Low humidity encourages electrostatic discharge.
- 50% humidity and lower is ideal.
- Equipment should not be placed in a closet that is not ventilated.
UPS (Uninterruptible Power Supply)
- A UPS is a power source that is always available, even during a main power loss.
- Battery backups provide continuous power.
- A standby UPS is always connected to main power and switches to battery backup when power is lost.
- A line interactive UPS is always connected to main power and also has connectivity to the internal battery reducing transition time to battery power.
- An on line UPS is always connected to the battery eliminating the need to switch over during power loss.
- Available features include auto shutdown, battery capacity, number of outlets, and phone/network line suppression.
Surge Suppressors
- Surge suppressors filter spikes or low voltage situations.
- Surges can be caused by storms or power grid changes.
- Surge suppressors divert extra voltage to the ground.
- Suppressors filter out noise on the electrical line.
- Joule ratings indicate the amount of voltage a suppressor can stop during a spike (600+ joules is ideal).
- Ensure the suppressor supports the total number of amps.
- Underwriters Laboratories (UL) tests suppressors for voltage let-through ratings (lower voltage is better).
