Environmental monitoring in the Cisco ASR 903 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 “System Specifications” section on page 2.
For an outside plant installation (cell site cabinet, hut etc.), it is required that the Cisco ASR 903 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
