Preparing to Install the Router 2-5
General Site Requirements
•
Ensure that the chassis cover is secure. The chassis is designed to allow cooling air to
flow effectively within it. An open chassis allows air leaks, which may interrupt and
redirect the flow of cooling air from internal components.
Configuring Equipment Racks
The following information will help you plan an acceptable equipment rack configuration.
•
Enclosed racks must have adequate ventilation. Ensure that the rack is not overly
congested because each unit generates heat. An enclosed rack should have louvered
sides and a fan to provide cooling air.
•
When mounting a chassis in an open rack, ensure that the rack frame does not block the
intake or the exhaust ports. If the chassis is installed on slides, check the position of the
chassis when it is seated all the way into the rack.
•
In an enclosed rack with a ventilation fan in the top, excessive heat generated by
equipment near the bottom of the rack can be drawn upward and into the intake ports of
the equipment above it in the rack. Ensure that you provide adequate ventilation for
equipment at the bottom of the rack.
•
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 are found by experimenting with different arrangements.
Power Supply Considerations
Check the power at your site to ensure that you are receiving “clean” power (free of spikes
and noise). Install a power conditioner if necessary.
Warning The device is designed to work with TN power systems. (To see translated

document that accompanied your router.)
