Safety Warnings
Warning
These warnings are translated into several languages in the Regulatory Compliance and Safety

Warning
Read the installation instructions before you connect the system to its power source.
Statement 10
Warning
The ports labeled “Ethernet,” “10BaseT,” “Token Ring,” “Console,” and “AUX” are safety extra-low
voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the
BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the
telephone network voltage (TNV) circuits.
Statement 22
Warning
This unit is intended for installation in restricted access areas. A restricted access area is where
access can only be gained by service personnel through the use of a special tool, lock and key, or
other means of security, and is controlled by the authority responsible for the location.

Warning
Before working on equipment that is connected to power lines, remove jewelry (including rings,
necklaces, and watches). Metal objects will heat up when connected to power and ground and can
cause serious burns or weld the metal object to the terminals.

Warning
Only trained and qualified personnel should be allowed to install or replace this equipment.
Statement
49
Warning
During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly
