Getting Started
What’s in This Chapter
This chapter describes warnings about the MAP/40, how to avoid electrostatic
damage to hardware items, how to unpack the kit, the importance of saving pack-
ing materials, items in the kit, and tools you need.
Heeding Warnings
Warnings and cautions appear throughout this book as needed when describing
procedures. These admonishments let you know when the actions you are about
to perform can harm you or the equipment unless you follow procedure steps as
listed.
The warnings that occur within this book are listed here as well for your informa-
tion.
!WARNING:
There is a magnet on the back of 855A adapter. Be sure that you do not
place this near the hard disk drive or new floppy diskettes.

1-2
Getting Started
!WARNING:
Notify the telephone company immediately if the MAP/100 is to be perma-
nently or temporarily disconnected from its present line/trunk circuits (Digital
circuits ONLY).
If you are turning off the power to the MAP/40 you are disconnecting from
the line/trunk circuits.
!WARNING:
If you disconnect the MAP/40 from the telephone network on a continuing
basis without letting the telephone company know, they can disconnect your
service (Digital circuits ONLY).
!WARNING:
If any of the telephone equipment is not operating properly, remove it imme-
diately from the telephone lines. Malfunctioning equipment can harm the
telephone network.
!WARNING:
Shut power off before removing the dress cover or access panel of the MAP/
40.
Perform a “soft” shutdown of the VIS operating system, if on-line, before
shutting off power to the system. See CONVERSANT Voice Information
System Version 3.1 Operations, 585-350-701, for information.
!WARNING:
Observe proper electrostatic discharge precautions when handling computer
components. Wear a ground wrist strap on your bare skin and connect to a
ground.
!WARNING:
The manufacturer(s) does not accept liability for a damaged unit if the unit is
not returned in the original packing materials and carton. The carton has
been designed to ensure product warranty and to prevent damage.
!WARNING:
Do not use the dress cover of the MAP/40 as a way to lift it.

Avoiding Electrostatic Discharge
Damage
The human body can collect thousands of volts of destructive static electricity
from ordinary activities, for example, walking on a rug, handling synthetic materi-
als, or wearing synthetic clothes. When this static electricity discharges onto
another surface at a different voltage potential, it is called
electrostatic discharge
or
ESD .
A person cannot feel ESD below approximately 3500 volts. However, only 30 volts
is needed to damage ESD-sensitive electronic components.
Circuit cards and packaging materials that contain ESD-sensitive components are
often marked with a yellow and black warning symbol. Proper grounding tech-
niques prevent the discharge of damaging static electricity from your body into
these ESD-sensitive components during handling.
There is no quick method of testing for ESD damage. Components that are dam-
aged may simply fail after a brief period of normal operation.
To avoid damaging ESD-sensitive components, follow these rules:
■Handle ESD-sensitive circuit cards only after you have attached a wrist
strap to the bare skin of your wrist. Attach the other end of the wrist strap to
a ground that terminates at the system ground, such as any unpainted
metallic chassis surface.
■Handle a circuit card by the faceplate or side edges only. Do not touch
components, leads, or connector areas (gold finger pins).
■Hold a short circuit card by the faceplate only. See Figure 1-1.
■Hold a larger circuit card as shown in Figure 1-2. Ensure palm is not in con-
tact with the board wiring side.
■Keep circuit cards away from plastics and other synthetic materials such as
polyester clothing.
■Do not hand circuit cards to another person unless that person is grounded
at the same potential level.
■Hold devices such as a hard disk, floppy drive, or cartridge tape drive as
you would a large circuit card. The ESD sensitive area of these compo-
nents is located on the bottom surface. Hold these drives on the areas rec-
ommended below.

Unpacking the Upgrade Kit
Save the shipping carton and all packing materials to use in the event the unit
needs to be returned to the manufacturer. Packing materials include anti-static
bags and bubble wrap as well as cardboard and foam inlays. If you have ordered
multiple kits, saving one carton and packing materials should be sufficient.
!CAUTION:
The manufacturer does not accept liability for a damaged unit if the unit is
not returned in the original packing materials and carton. The carton has
been designed to ensure product warranty and to prevent damage.
If you do need to return a kit, complete the yellow GBCS return repair tag and
attach it to the unit. The factory information packet included in the kit carton con-
tains the yellow return repair tag.
