Site Planning
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 ASR 1000 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 ASR 1000 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 5-3.
