Installation manual

1 Be sure that the ventilation in the wiring closet is adequate to maintain a temperature below 104° F
(40° C).
2 Install a reliable air conditioning and ventilation system.
3 Keep the ventilation in the wiring closet running during non-business hours; otherwise, the
equipment can overheat.
4 Maintain an ambient operating temperature of 32° to 104° F (0° to 40° C).
5 Maintain a storage temperature of -40° to 158° F (-40° to 70° C).
Controlling Humidity
Maximize equipment life by keeping relative humidity between allowable limits.Keep operating
humidity between 50% and 70% relative humidity (non-condensing) during typical operation.
Following Spacing and Airflow Requirements
Be sure that walls and other equipment do not block the air intake or outflow on an Extreme Networks
switch.
1 Leave a minimum of 24 inches (61 cm) between any solid wall or other obstruction and the front
and back of the chassis.
2 Measure the air temperature approximately 1 inch (2.5 cm) from the front of I/O slot 1. The
temperature should be less than 104 °F (40 °C).
Protecting from Electrostatic Discharge
Your system must be protected from static electricity or electrostatic discharge (ESD).
1 Remove materials that can cause electrostatic generation (such as synthetic resins) from the
equipment location. Check the appropriateness of floor mats and flooring.
2 Connect metal chassis, conduit, and other metals to ground using dedicated copper grounding lines.
3 Use electrostatically safe equipment.
If you are working with pluggable interface modules, wear an ESD-preventive device such as a wrist
strap, and connect the metal end to a grounded equipment rack or other source of ground.
