Magnetism, Shock and Vibration | Dell 2100/200, 2100/180 manual

•Ensure that all expansion slots are covered either by a card-mounting bracket or by a metal filler bracket and that each drive bay has a drive and/or a metal insert installed. These brackets and metal inserts are available from Dell.

•Ensure that the screws on all peripheral cable con- nectors are securely fastened to their corresponding connectors on the back of the computer.

•Always use shielded cables with metal connector shells for attaching peripherals to the computer.

To prevent the possibility of RFI from a computer affect- ing TV reception, follow these guidelines:

•Keep any TV set at least 6 ft away from the com- puter system.

•Use cable TV when possible.

•Use a directional outdoor TV antenna.

•Attach line filters to the TV set.

•Use 75-ohm coaxial cable for the TV set rather than twin-lead antenna wire.

•If interference occurs, rotate the computer or the TV set 90 degrees.

Magnetism

Because they store data magnetically, diskettes and hard- disk drives are extremely susceptible to the effects of magnetism. Diskettes should never be stored near mag- netic sources such as the following:

•Monitors

•TV sets

•Printers

•Telephones with real bells

•Fluorescent lights

Shock and Vibration

Excessive shock can damage the function, external appearance, and physical structure of a system. Each Dell system has been designed to operate properly after with- standing a minimum of six consecutively executed shock pulses in the positive and negative x, y, and z axes. Each shock pulse can measure up to 5 gravities (G) for up to

11 milliseconds (ms). In storage, the system can withstand shock pulses of 20 G with a velocity change of 1397 millimeters (mm) per second (55 inches per second).

Excessive vibration can cause the same problems as men- tioned earlier for shock, as well as cause components to become loose in their sockets or connectors. Systems can be subject to significant vibration when being transported by vehicle or when operated in an environment with machinery that causes vibration.

Each Dell system, when operating, is designed to with- stand 0.25 G (half-sine wave) at a sweep of 3 to 300 hertz (Hz) for 15 minutes. In storage, the system can withstand 0.5 G at 3 to 300 Hz for 15 minutes.

Power Source Interruptions

Computer systems are especially sensitive to variations in voltage supplied by the AC power source. Over- voltage, undervoltage, and transients (or spikes) can erase data from memory or even cause components to fail. To pro- tect against these types of problems, power cables should always be properly grounded and one or both of the follow- ing methods should be used:

•Use one of the power protection devices described in the following section, “Power Protection Devices.”

•Place the system on a dedicated power circuit (rather than sharing a circuit with other heavy electrical equipment). In general, do not allow the system to share a circuit with any of the following:

—Kitchen appliances

—Copier machines

—Air conditioners

—Vacuum cleaners

—Space heaters

—Power tools

—Teletype machines

—Adding machines

—Laser printers

—Facsimile machines

—Any other motorized equipment
