NOTE
Extreme Networks recommends that you consult an electrical contractor for commercial building and
wiring specifications.

Temperature

Extreme Networks equipment generates a significant amount of heat. It is essential that you provide a
temperature-controlled environment for both performance and safety.
Install the equipment only in a temperature- and humidity-controlled indoor area that is free of airborne
materials that can conduct electricity. Too much humidity can cause a fire. Too little humidity can
produce electrical shock and fire.
Follow these general thermal recommendations for the location of your equipment:
Be sure that the ventilation in the wiring closet is adequate to maintain a temperature
G
below 104° F (40° C).
Install a reliable air conditioning and ventilation system.
G
Keep the ventilation in the wiring closet running during non-business hours; otherwise, the
G
equipment can overheat.
Maintain an ambient operating temperature of 32° to 104° F (0° to 40° C).
G
Maintain a storage temperature of -40° to 158° F (-40° to 70° C).

NOTE
As with all electrical equipment, Extreme Networks product lifetimes degrade with increased temperature.
If possible, temperatures should be kept at approximately 78° F (25° C) or lower.

Humidity

To maximize equipment life, keep operating humidity between 50% and 70% relative humidity (non-
condensing) during typical operation. The equipment can operate between 10% and 95% relative
humidity (non-condensing) for short intervals.

Spacing Requirements and Airflow

Be sure that cables and other equipment do not block the air intake or outflow on an Extreme Networks
switch. It is best to have at least 3 inches (8 cm) of clear space in front of the air intake and outflow
vents on the sides of the switch; airflow moves from side to side. For proper airflow through a Summit
family switch, leave clear space on the left and right sides of the switch.
Depending on other conditions in the equipment room, it may be possible to install the switches closer
to each other; consult your Extreme Networks Customer Support representative for guidance.
