Note the following points:
• When installing the router in a back-to-back position with another device, ensure that there is a minimum
• If airflow through the equipment rack and the routers that occupy it is blocked or restricted, or if the
• The site must be as dust-free as possible. Dust tends to clog the router fans, reducing the flow of cooling
• Enclosed racks must have adequate ventilation. Ensure that the rack is not congested because each router
• When mounting a router in an open rack, ensure that the rack frame does not block the exhaust fans.
• When rack-installed equipment fails, especially equipment in an enclosed rack, try operating the equipment
• Avoid installing the router in a location in which the router air intake vents may draw in the exhaust air
Site Power Guidelines
The chassis has specific power and electrical wiring requirements. Adhering to these requirements ensures
the reliable operation of the system. Follow these precautions and recommendations when planning your site
