Jumper Setting

EBC 340 User’s Manual 12
This chapter of the User’s Manual describes how to set jumpers.
Note: The procedures that follow are generic for all EBC340.
2.1 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.
2.2 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 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

EBC 340 User’s Manual 13
ready for installation.
Use correct screws and do not over tighten screws.
2.3 Setting Jumpers
A jumper is the simplest kind of electric switch. It consists of two metal pins and a cap. When
setting the jumpers, ensure that the jumper caps are placed on the correct pins. When the
jumper cap is placed on both pins, the jumper is SHORT. If you remove the jumper cap, or place
the jumper cap on just one pin, the jumper is OPEN. Please see the following illustrations
The illustrations on the right
show a 2-pin jumper. When the
jumper cap is placed on both
pins, the jumper is SHORT. If
you remove the jumper cap, or
place the jumper cap on just
one pin, the jumper is OPEN.
Open (Off) Short (On)
These illustrations show a
3-pin jumper. Pins 1 and 2 are
SHORT.
