Site Selection Guidelines

The Cisco ASR 1000 Series Routers require specific environmental operating conditions. Temperature,
humidity, altitude, and vibration can affect the performance and reliability of the router. The following
sections provide specific information to help you plan for the proper operating environment.
The Cisco ASR1000 Series Routers are designed to meet the industry EMC, safety, and environmental
standards described in the Regulatory, Safety, and Compliance Information for Cisco ASR 1000 Series
Aggregation Services Routers document.

Site Environmental Requirements

Environmental monitoring in the Cisco ASR1000 Series router protects the system and components from
damage caused by excessive voltage and temperature conditions. To ensure normal operation and avoid
unnecessary maintenance, plan and prepare your site configuration before installation. After installation,
make sure the site maintains the environmental characteristics as shown in
Table 3-3

Position system cables and power supply cables carefully. Route system cables and the power supply
cable and plug so that they cannot be 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 system
component damage.
