Installation Guide

• Be sure that each wiring closet has a suitable ground. All equipment racks and equipment installed
in the closet should be grounded.
• Be sure that all system environmental requirements are met, such as ambient temperature and
humidity.
Note
We recommend that you consult an electrical contractor for commercial building and wiring
specifications.
Controlling the 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.
The ambient operating temperature for most ExtremeSwitching switches ranges from 0°C (32°F) to
45°C (113°F) or 50°C (122°F). (Check the descriptions in Summit Switches on page 24 for the
temperature range that applies to your switch model.) As with all electrical equipment, however,
Extreme Networks product lifetimes degrade with increased temperature. Ideally, therefore,
temperatures should be kept at or below 25°C (77°F).
Observe these additional thermal recommendations for the location where you plan to install your
equipment:
• Ensure that the ventilation in the wiring closet is adequate to maintain a temperature below 40°C
(104°F).
• Install a reliable air conditioning and ventilation system.
• Keep the ventilation in the wiring closet running during non-business hours; otherwise, the
equipment can overheat.
• Maintain a storage temperature between -40°C (-40°F) and 70°C (158°F).
Table 109 on page 224 summarizes the behavior of ExtremeSwitching switches when they experience
high operating temperatures.
Table 110 on page 224 lists the ambient temperature range for ExtremeSwitching switches. As with all
electrical equipment, however, Extreme Networks product lifetimes degrade with increased
temperature. Ideally, therefore, temperatures should be kept at or below 25°C (77°F).
