Other Safety/Operation Standards

The following are some of the other environmental influences that may affect L Class servers.

Vibration

Continuous vibration can cause a slow degradation of mechanical parts and, when severe, can cause data

errors in disc drives. Mechanical connections such as printed circuit assembly (PCA) connectors, cable

connectors, and processor backplane wiring can also be affected by vibration.

Flammable Materials

Fundamental safeguards for computer systems should include a site well away from any sources of potential

damage. The system should not be installed or operated in an environment where there is a risk of fire or

explosion due to the existence of highly flammable gases, volatile liquids, or combustible dust.

Airborne Contaminants

Airborne contaminants and particles of a certain size and hardness can damage your computer system,

particularly disc drives. Corrosive gases and/or solvent vapors such as those from liquid spirit duplicating

equipment and wet-process photo copiers can also cause damage. Some of the most common contaminants are

dust, smoke, ash, eraser debris, food crumbs, and salty air.

Electrostatic Discharge

If there is an abnormally high level of static electricity at your computer system's location (15 KV or higher),

anyone can cause "sparking" upon contact with the equipment. Carpeting and/or low humidity is a major

source of static electricity, especially in dry and cold climates. Static electricity can often be significantly

reduced by using a humidifier.

NOTE Hewlett-Packard recommends a heat evaporating-type humidifier and strongly advises against

using a cold water atomizer type humidifier

Other ways to minimize electrostatic discharge are by using specially grounded mats in front of the computer

system or by treating carpeting with anti-static spray. If spray is used, apply it while the system is turned off.

Sprays are very temporary and must be reapplied frequently.

CAUTION Anti-static spray is not recommended because it gets into the system intake filter and coats the

circuitry.
