Safety Precautions When you handle components in a CoreBuilder 9000 system, be sure
that you follow all safety precautions. To avoid electric shocks, burns, or
equipment damage, read and follow these warnings:
WARNING: This switching module must be installed, removed, or
replaced only by trained service personnel.
WARNING: Hazardous energy exists within the system. Use extreme
caution when you install, remove, or replace any module. When the
system is on:
■
Never insert metal objects such as a screwdriver or a finger with
jewelry into open module slots.

Do not touch any connections within the chassis with your hands or
fingers.
ESD Safety Information
Electrostatic discharge (ESD) can damage components of the module.
ESD, which occurs when the module is improperly handled, can cause
complete or intermittent failures on the module.
CAUTION: To prevent ESD-related damage:
