Keep your system components away from radiators and heat sources and do not block cooling vents.
Do not spill food or liquids on your system components and never operate the product in a wet
environment.
Do not push any objects into the openings of your system components. Doing so can cause fire or
electric shock by shorting out interior components.
Position system cables and power supply cable carefully. Route system cables and the power supply
cable and plug so that they are not stepped on or tripped over. Be sure that nothing else rests on your
system component cables or power cable.
Do not modify power cables or plugs. Consult a licensed electrician or your power company for site
modifications. Always follow your local and national wiring rules.
If you turn off your system, wait at least 30 seconds before turning it on again to avoid damage of
system components.
The site meets the environmental requirements.
The site's air conditioning system can compensate for the heat dissipation of the
Cisco ASR 920 Series Router.
The floor space that the Cisco ASR 920 Series Router occupies can support the weight of the
system.
Electrical service to the site complies with the requirements.
