When deciding where to place the Cisco Catalyst Express 520 switch, observe these requirements:
•
Altitude at the installation site is not greater than 10,000 feet (3,049 meters).
•
Humidity around the switch does not exceed 85 percent.
•
Temperature around the unit does not exceed 113°F (45°C).
Note
If the switch is installed in a closed environment or in a multirack assembly, the
temperature around it might be greater than normal room temperature.
•
The heat sinks and the bottom of the Cisco Catalyst Express 520 switch might be hot to the touch
if the switch is operating at its maximum temperature 113°F (45°C) and is in an environment that
exceeds normal room temperature (such as a closet, a cabinet, or a closed or multirack assembly).
•
Do not place any items on the top of the switch.
•
Airflow around the switch and through the vents is unrestricted.
Note
We strongly recommend that you allow at least 3 in. (7.6 cm) of clearance around the
ventilation openings to prevent airflow restriction and overheating.
•
Do not stack switches or place switches side-by-side unless they are separated on all sides by at
least 3 inches (7.6 cm) of clearance from each other.
•
Clearance at front and back panels is such that
–
Airflow around the switch and through the vents is unrestricted.
–
Front-panel LEDs can be easily read.
