Safety Warnings for Cisco Network Modules
The following safety warning statements apply to all hardware procedures involving Cisco network
modules for Cisco access routers. Translations of these warnings are available in the
Cisco Network
Modules and Interface Cards Regulatory Compliance and Safety Information
document, which ships
with all individual Cisco network module orders, and is also available online.
Warning
Before working on a chassis or working near power supplies, unplug the power cord on AC units;
disconnect the power at the circuit breaker on DC units.
Statement 12
Warning
Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with
both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent
damage to the chassis and components, never attempt to lift the chassis with the handles on the
power supplies or on the interface processors, or by the plastic panels on the front of the chassis.
These handles were not designed to support the weight of the chassis.
Statement 194
Warning
Only trained and qualified personnel should be allowed to install or replace this equipment.
Statement 1030
Warning
Ultimate disposal of this product should be handled according to all national laws and
regulations.
Statement 1040
The following warnings apply in Australia:
Warning
Do not touch the power supply when the power cord is connected. For systems with a power
switch, line voltages are present within the power supply even when the power switch is OFF and
the power cord is connected. For systems without a power switch, line voltages are present within
the power supply when the power cord is connected.
Statement 4
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.
