Setting Up the System 2-5
System Care
The system is a durable system built for dependable use. With protective
measures and proper care, you can prevent problems and promote the
successful operation and long life span of the system.
Protecting Your System From Damage
There are several ways that you can protect the system from possible
damage. NECC strongly recommends the following protective measures.
!
Connect a surge suppressor between the system and a grounded wall
outlet. A surge suppressor protects the system from sudden transient
increases and decreases in electrical power.
Be sure to connect all peripherals, such as a printer, to the surge
suppressor. The surge protector should be the only device that you
plug into the wall outlet.
!
Avoid repeated power-on cycles. These subject the system
components to temperature variations and stress.
!
Disconnect the system from telephone and power lines when an
electrical storm threatens. If you have a fax/modem, lightning can
travel in on the phone line and damage both the fax/modem and the
system unit. Lightning can also travel in on power lines and damage
the LCD panel and system unit.
!
Be sure that system power is off before connecting or disconnecting a
cable (USB devices do not require powering down the system when
connecting). Never make cable changes when the system power is on.
Doing so can damage the system and its peripherals.
!
Use BIOS Setup utility options to protect against viruses (see
Chapter 3). You should also use the Network Associates VirusScan
protection software provided with the system to protect the system
from viruses.
If you plan to use software programs other than NECC-supplied
software, NECC strongly recommends that you take the necessary
steps, such as virus checks, to protect the system.
