Dell OptiPlex N and OptiPlex NX Systems User’s Guide

Magnetism

Because they store data magnetically, hard-disk drives 
are extremely susceptible to the effects of magnetism.

Speakers

Audio speakers can be a source of magnetic energy if 
they are not properly shielded. Speakers used in music 
systems are typically enclosed in wooden cabinets, which 
provide no magnetic shielding. Multimedia speakers for 
computer systems are magnetically shielded inside a 
metallic case and are thus the only type of speakers rec-
ommended for use with multimedia computer systems.

Shock and Vibration

Excessive shock can damage the function, external 
appearance, and physical structure of a system. Excessive 
vibration can cause the same problems as excessive 
shock does and can cause components to become loose in 
their sockets or connectors. Systems can be subjected 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 a left side (for vertical orientation using the 
optional stand) and bottom half-sine pulse with a change 
in velocity of 50.8 centimeters per second (cm/sec) 
(20 inches/sec). In storage, the system can withstand a 
26,478-cm/sec

2

 (27-gravities) faired square wave with a 

velocity change of 508 cm/sec (200 inches/sec).

Power Source Interruptions

Computer systems are sensitive to variations in voltage 
supplied by the AC power source. Overvoltage, under-
voltage, and transients (or spikes) can erase data from 
memory or even cause components to fail. To protect 
against such problems, power cables should always be 
properly grounded, you should use a power protection 
device, and you should place the system on a circuit that 
does not contain any heavy electrical equipment.

Your network administrator should verify your power 
source and network cables; however, you should ensure 
that your system is connected to a dedicated power cir-
cuit and that it is not sharing a circuit with any of the 
following:

Kitchen appliances

Copier machines

Air conditioners

Vacuum cleaners

Space heaters

Power tools

Teletype machines

Adding machines

Any other motorized equipment

Another threat to a system’s supply of power is surges or 
blackouts caused by electrical storms. Whenever 
possible, turn off the computer and any peripherals and 
unplug them from their power sources during 
thunderstorms.

If a blackout occurs

even a temporary

 

one

turn off the 

system immediately and disconnect it from its power 
source. Leaving the system on may cause problems when 
the power is restored; all other appliances left on in the 
area can create large voltage spikes that could damage the 
system.

P

ower Protection Devices

Various levels of power protection are available for your 
system.

Surge Protectors

Surge protectors prevent voltage spikes, such as those 
caused during electrical storms, from entering a system 
through the AC power source. These devices are avail-
able in a variety of types and usually provide a level of 
protection commensurate with the cost of the device.
