Router Environmental Requirements
Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling air through
•
the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can
be found by experimenting with different configurations.
When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the
•
equipment by itself, if possible. Power off other equipment in the rack (and in adjacent racks) to
allow the router under test a maximum of cooling air and clean power.
