Chapter 2: Jumpers and Connectors

This chapter describes how to set the jumpers and connectors on the
NViS 2280 motherboard.

Before You Begin

• Ensure you have a stable, clean working environment. Dust and dirt can

get into components and cause a malfunction. Use containers to keep
small components separated.

• Adequate lighting and proper tools can prevent you from accidentally

damaging the internal components. Most of the procedures that follow
require only a few simple tools, including the following:

- A Philips screwdriver

- A flat-tipped screwdriver

- A set of jewelers screwdrivers

- A grounding strap

- An anti-static pad

• Using your fingers can disconnect most of the connections. It is

recommended that you do not use needle-nosed pliers to disconnect
connections as these can damage the soft metal or plastic parts of the
connectors.

• Before working on internal components, make sure that the power

is off. Ground yourself before touching any internal components, by
touching a metal object. Static electricity can damage many of the
electronic components. Humid environments tend to have less static

electricity than dry environments. A grounding strap is warranted
whenever danger of static electricity exists.

Precautions

Computer components and electronic circuit boards can be damaged
by discharges of static electricity. Working on computers that are still
connected to a power supply can be extremely dangerous.

Follow the guidelines below to avoid damage to your computer or
yourself:
• Always disconnect the unit from the power outlet whenever you are

working inside the case.

• If possible, wear a grounded wrist strap when you are working inside the

computer case. Alternatively, discharge any static electricity by touching
the bare metal chassis of the unit case, or the bare metal body of any
other grounded appliance.

• Hold electronic circuit boards by the edges only. Do not touch the

components on the board unless it is necessary to do so. Don’t flex or
stress the circuit board.

• Leave all components inside the static-proof packaging that they shipped

with until they are ready for installation.

• Use correct screws and do not over tighten screws.
