This guide is intended for trained technical personnel only. Do not
attempt to remove or replace a CoreBuilder 3500 10/100BASE-TX Fast
Ethernet module if you do not have the proper training from 3Com. For
training information, call 1-800-NET-3COM.
WARNING: Hazardous energy exists within the system. Use extreme
caution when you remove or replace the 10/100BASE-TX Fast Ethernet
module. Always be careful to avoid electric shock or equipment damage.
See "Safety Precautions" and "ESD Safety Information" next.
Be sure to follow all safety precautions when you replace components in
the system. To avoid electric shocks, burns, or equipment damage, read
and follow these warnings:
WARNING: When the system is on, never insert a metal object, such as a
screwdriver or a finger with jewelry, into open module slots.
WARNING: When the system is on, do not touch any connections inside
the chassis with your hands or fingers.
Electrostatic discharge (ESD) can damage components on the module.
ESD, which occurs when the module is improperly handled, can cause
complete or intermittent failures. To prevent ESD-related damage:
Always wear an ESD wrist strap connected to proper ground. Ensure
that the wrist strap makes good skin contact.
Keep the module in its antistatic shielded bag until you are ready to
install it.
Always handle the module by its edges.
Do not touch the components, pins, leads, or solder connections.
