Safety Precautions When you install or replace 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: Allow only trained service personnel to install, remove, or
replace an EME.
WARNING: Hazardous energy exists within the system. Use extreme
caution when you install, remove, or replace an EME. 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 system.
ESD, which occurs when the EME is improperly handled, can cause
complete or intermittent failures.
CAUTION: To prevent ESD-related damage:
Always wear an ESD wrist strap (not provided) when you handle a
module, ensuring that the strap makes good skin contact and is
properly grounded.
Keep the EME in its antistatic bag until you are ready to inspect or
install it.
