2.5.1 Maintenance Practices

Learn methods to maintain PC equipment in order to extend component life expectancy.

Create a Proper Environment

• keep the temperature at 70-74 degrees Fahrenheit
• keep the humidity levels at 40-70%
• ensure that computer rooms have separate and redundant cooling systems
• use a positive pressure system in computer rooms
• frequently clean systems that operate in dirty, smoky, or dusty environments

Electromagnetic-Interference

• use shielded cables
• run your cabling in conduits

Radio-Frequency-Interference

• try moving to a wireless operation that works in 5 GHz (gigahertz)

Magnetic-Interference

Any data stored on magnetic data, like CD & DVD Drives or tape recordings is at risk of corruption from any source of a magnetic field:

• speakers
• motors
• fans
• space heaters (shocking) Try moving to a:
• solid state drive
• USB flash drive

Cleaning Computers

Maintain Idle Computers

• after receiving a shipped system:
  • let the unpackaged system sit at room temperature for ~6 hours, to allow condensation to evaporate
• use covers and cases to protect equipment that's not in use
• use cable ties and anchors to keep cabling organized
• regularly perform backups of important data
• make sure that the airflow is going the right way.
  • if internal fans are installed backwards, it can negate the cool airflow and cause the system to overheat during use.
