Preparing for Installation

Site Planning Checklist

Use the following checklist to perform and account for all the site planning tasks described in this chapter:
• The site meets the environmental requirements.
• The site's air conditioning system can compensate for the heat dissipation of the Cisco ASR 902 Router.
• The floor space that the Cisco ASR 902 Router occupies can support the weight of the system.
• Electrical service to the site complies with the requirements.
• The electrical circuit servicing the Cisco ASR 902 Router complies with the requirements.
• Consideration has been given to the console port wiring and limitations of the cabling involved, according
• The Cisco ASR 902 Router Ethernet cabling distances are within the prescribed limitations.
• The equipment rack in which you plan to install the Cisco ASR 902 Router complies with prescribed
• When selecting the location of the rack, careful consideration must be given to safety, ease of maintenance,

Site Selection Guidelines

The Cisco ASR 902 Router requires 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 902 Router is designed to meet the industry EMC, safety, and environmental standards
described in the Product Documentation and Compliance for the Cisco ASR 900 Series Aggregation Services
Routers document.

Environmental Requirements

The Cisco ASR 902 Router is Telcordia GR-3108-CORE Class-1/GR-63-Core Indoor compliant. Environmental
monitoring of the Cisco ASR 902 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 that the site maintains
the environmental characteristics described in the
For an outside plant installation (cell site cabinet, hut etc.), it is required that the Cisco ASR 902 Router be
protected against airborne contaminants, dust, moisture, insects, pests, corrosive gases, polluted air or other
reactive elements present in the outside air. To achieve this level of protection, we recommend that the unit
be installed in a fully sealed enclosure or cabinet. Examples of such cabinets include IP65 cabinets with heat
exchanger complying with Telecordia GR487. Temperature must be maintained within –40ºC to 65ºC.
