CiscoASR 9000 Series Aggregation Services Router Hardware Installation Guide
Chapter1 Preparing for Installation
Safety Guidelines
•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 9000Series 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:
Warning
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
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.
Warning
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
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.
Note Check the resistance value of the ESD-preventive strap periodically. The measurement should be
between 1 and 10 megohms.
