• Operate Cisco equipment safely by using it in accordance with its electrical ratings and product usage
instructions.
• Do not work alone if potentially hazardous conditions exist.
• Always unplug the power cables when performing maintenance or working on the router, unless the
replacement part is hot swappable and designed for online insertion and removal (OIR).
• Ensure that the installation of the router is in compliance with national and local electrical codes: in the
United States, National Fire Protection Association (NFPA) 70, United States National Electrical Code;
in Canada, Canadian Electrical Code, part I, CSA C22.1; in other countries, International Electrotechnical
Commission (IEC) 364, part 1 through part 7.
Compliance and Safety Information
The Cisco ASR 9000 Series Routers are designed to meet the regulatory compliance and safety approval
requirements. For detailed safety information, see:
Regulatory Compliance and Safety Information for the
Cisco ASR 9000 Series Routers.
Laser Safety
Single-mode Cisco ASR 9000 Series line cards are equipped with lasers. The lasers emit invisible radiation.
Do not
stare into open line card ports. Observe the following warning to prevent eye injury:
Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected,
avoid exposure to laser radiation and do not stare into open apertures. Statement 70
Warning
Energy Hazard
The Cisco ASR 9000 Series Routers can be configured for a DC power source. Do not touch terminals while
they are live. Observe the following warning to prevent injury.
Hazardous voltage or energy may be present on power terminals. Always replace cover when terminals are
not in service. Be sure uninsulated conductors are not accessible when cover is in place. Statement 1086
Warning
Preventing Electrostatic Discharge Damage
Many router components can be damaged by static electricity. Not exercising the proper electrostatic discharge
(ESD) precautions can result in intermittent or complete component failures. To minimize the potential for
ESD damage, always use an ESD-preventive antistatic wrist strap (or ankle strap) and ensure that it makes
good skin contact.
