Preparing for Installation
• Ensure that the chassis cover and module rear panels are secure. All empty network module slots, interface
card slots, and power supply bays must have filler panels installed. The chassis is designed to allow
cooling air to flow within it, through specially designed cooling slots. A chassis with uncovered openings
permits air leaks, which, in turn, may interrupt and reduce the flow of air across internal components.
• 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.
• Do not spill food or liquid on any system components and do no operate in a wet environment.
• Do not push any objects into the openings of your system components. Doing so can cause fire or electric
shock by shorting out interior components.
• Route system cables, and the power supply cable and plug so that they cannot be stepped on or tripped
over. Be sure that nothing else rests on your system component cables or power cable.
• Do not modify power cables or plugs. Consult a licensed electrician or your power company for site
modifications. Always follow your local and national wiring rules.
• If you turn off your system, wait at least 30 seconds before turning it on again to avoid system component
damage.
Temperature, humidity, altitude, and vibration can affect the performance and reliability of the router. After
installation, ensure that the site maintains the environmental characteristics shown in this table:
Environmental Characteristic
Steady State Operating
Storage
Humidity operating (noncondensing)
Humidity nonoperating (noncondensing)
Altitude operating: over allowable temperature range
(0 to 40 degrees C)
Altitude, nonoperating: over allowable temperature
range
Thermal shock non-operating with change over time
of 3 minute
Thermal Shock - Operating at 2.5 degree C per minute
Note
When an equipment that is installed in a rack (particularly in an enclosed rack) fails, try, if possible, to operate
the equipment in isolation. Power off other equipment in the rack (and in adjacent racks) to allow the equipment
to be tested in a condition that has maximum cool air and clean power.
