Maintaining the System

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 bells
Fluorescent lights

Excessive shock can damage the function, external appearance, and physical struc-
ture of a system. Each Dell system has been designed to operate properly even after
withstanding a minimum of six consecutively executed shock pulses in the positive
and negative x, y, and z axes (one pulse on each side of the system). Each shock pulse
can measure up to 50 gravities (G) for up to 2 milliseconds (ms). In storage, the sys-
tem can withstand shock pulses of 92 G for 2 ms.
Excessive vibration can cause the same problems as mentioned 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 withstand 0.25 G (half-sine wave) at
a sweep of 3 to 200 hertz (Hz) for 15 minutes. In storage, the system can withstand
0.5 G at 3 to 200 Hz for 15 minutes.
