Dust and Particles, Corrosion | Dell 2100/180, 2100/200 guide

Dust and Particles

A clean operating environment can greatly reduce the negative effects of dust and other particles, which act as insulators and interfere with the operation of a system’s mechanical components. Also, in addition to regular cleaning, you should follow these guidelines to deter con- tamination of the computer equipment:

•Do not permit smoking anywhere near the system.

•Do not permit food or drink near the system.

•Use dust covers when the system is not in use.

•Keep all diskettes in a closed diskette box when not in use.

•Close windows and outside doors to keep out air- borne particles.

Corrosion

The oil from a person’s fingers or prolonged exposure to high temperature or humidity can corrode the gold-plated edge connectors and pin connectors on various devices in the computer. This corrosion on computer connectors is a gradual process that can eventually lead to intermittent failures of electrical circuits.

To prevent corrosion, you should avoid touching contacts on boards and cards. Protecting the system from corro- sive elements is especially important in moist and salty environments, which tend to promote corrosion. Also, as a further deterrent to corrosion, the system should not be used in extreme temperatures, as explained in “Tempera- ture” discussed earlier in this appendix.

ESD

ESD results from the buildup of static electricity on the human body and certain other objects. This static elec- tricity is often produced by simple movements such as walking across a carpet. ESD is a discharge of a static electrical charge, which occurs when a person whose body contains such a charge touches a component in the computer. This static discharge can cause components, especially chips, to fail. ESD is a problem particularly in dry environments where the relative humidity is below

50 percent. To reduce the effects of ESD, you should observe the following guidelines:

•When working inside the computer, wear a wrist grounding strap. If a wrist grounding strap is unavailable, touch an unpainted metal surface on the chassis periodically to neutralize any static charge.

•If at all possible, stand on a concrete floor while working inside the computer.

•Use an antistatic floor mat when working inside the computer.

•If it is necessary to work in a carpeted area, spray the carpet with an antistatic spray and allow it to dry before beginning to work inside the computer.

•Keep components in their antistatic packaging until they are installed.

•Avoid wearing clothing made of wool or synthetic materials.

Electromagnetic and Radio Frequency Interference

Electromagnetic interference (EMI) and radio frequency interference (RFI) from a computer can adversely affect devices such as radio and television (TV) receivers oper- ating near the computer. Radio frequencies emanating from a computer system can also interfere with cordless and low-power telephones. Conversely, RFI from high- power telephones can cause spurious characters to appear on the system’s monitor screen.

RFI is defined as any EMI with a frequency above

10 kilohertz (kHz). This type of interference can travel from the computer to other devices through the alternat- ing current (AC) power cable and power source or through the air like transmitted radio waves. The Federal Communications Commission (FCC) publishes specific regulations to limit the amount of EMI and RFI emitted by computing equipment. Each Dell system meets these FCC regulations.

To reduce the possibility of EMI and RFI, follow these guidelines:

•Operate the system only with the computer cover installed.
