• Appendix E, Installation Checklist provides a checklist to ensure
that all necessary procedures have been completed. Use of the
installation checklist is required to ensure a quality installation, all
completed tasks should be checked off and those not completed
should be duly noted as to the reason why. This checklist should
be turned in as part of your job complete paperwork.
• Glossary provides definitions for telecommunication acronyms

Safety Information and Instructions
Safety Labels This document may contain safety labels in the form of DANGER,
WARNING, and CAUTION statements.
These admonishments have the following definitions:
DANGER
...........................................................................................................................................................................
DANGER shows the presence of a hazard that will cause death
or severe personal injury if the hazard is not avoided.
WARNING
...........................................................................................................................................................................
WARNING shows the presence of a hazard that can cause death
or severe personal injury if the hazard is not avoided.
CAUTION
...........................................................................................................................................................................
CAUTION shows the presence of a hazard that will or can cause
minor personal injury or property damage if the hazard is not
avoided. Caution is also used for property-damage-only
accidents. This includes equipment damage, loss of software, or
service interruption.
The alert symbol appears throughout this document to alert the
user to these safety labels.

Electrostatic Discharge
ESD Considerations
CAUTION
Industry experience has shown that all integrated circuit packs
can be damaged by static electricity that builds up on work
surfaces and personnel. The static charges are produced by
various charging effects of movement and contact with other
objects. Dry air allows greater static charges to accumulate.
Higher potentials are measured in areas with low relative
humidity, but potentials high enough to cause damage can occur
anywhere.
In order to prevent damage by electrostatic discharge the following
precautions should be observed when handling circuit packs:
• Assume all circuit packs contain solid state electronic components
that can be damaged by ESD.
• When handling circuit packs (storing, inserting, removing, etc.) or
when working on the backplane, always wear a grounded wrist
strap such as the one shown in Figure 1, Static Control Wrist Strap
(page xxi) or wear a heel strap and stand on a grounded, static
dissipating floor mat. If a static dissipating floor mat is used, be
sure that it is clean to ensure a good discharge path.
• Handle all circuit packs by the faceplate or latch and by the top
and bottom outermost edges. Never touch the components,
conductors, or connector pins.
• Observe warning labels on bags and cartons. Whenever possible,
do not remove circuit packs from antistatic packaging until ready
to insert them into slots.
• If possible, open all circuit packs at a static safe work position,
using properly grounded wrist straps and static dissipating table
mats. If a static dissipating floor mat is used, be sure that it is clean
to ensure a good discharge path.
• Always store and transport circuit packs in static safe packaging.
Shielding is not required unless specified.
• Keep all static generating materials such as food wrappers,
plastics, and styrofoam containers away from all circuit packs.
Upon removal from bay, immediately put circuit packs into static
safe packages.
• Whenever possible, maintain relative humidity above 20 percent.
