CHAPTER 2: Setting Up and Getting Started

Preparing power
connections
Protecting from power source problems
During a power surge, the voltage level of electricity
coming into your computer can increase to far above
normal levels and cause data loss or system damage.
Protect your computer and peripheral devices by
connecting them to a
surge protector
, which absorbs
voltage surges and prevents them from reaching your
computer.
An
uninterruptible power supply
(UPS) supplies
battery power to your computer during a power
failure. Although you cannot run your computer for
an extended period of time with a UPS, a UPS lets you
run your computer long enough to save your work and
shut down your computer normally.
Connecting to a
broadband modem or
network
You can connect your computer to a broadband (cable
or DSL) modem or to a wired Ethernet network.
Warning
High voltages can enter your computer through both the
power cord and the modem connection. Protect your computer by
using a surge protector. If you have a telephone modem, use a surge
protector that has a modem jack. If you have a cable modem, use
a surge protector that has an antenna/cable TV jack. During an
electrical storm, unplug both the surge protector and the modem.
Important
Your computer has a built-in Ethernet (network) jack.
