Before You Begin - Nexcom PEAK 7220VL2G User Manual

This chapter of the User's Manual describes how to set jumpers.
Note: The procedures that follow are generic for all of the PEAK735 models

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 environment 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 the 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 (such as the PEAK7220VL2G board) 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.
