Controlling The Temperature; Controlling The Humidity Level - Extreme Networks ExtremeRouting SLX 9740 Hardware Installation Manual

Controlling the Temperature

•
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.
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 no higher than
40°C (104°F). (Some configurations support higher operating temperatures. See Environmental
Data in "Technical Specifications" for details.)
•
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).
When internal system temperatures exceed the thermal shutdown temperature limit (typically about
20°C higher than normal system operating temperatures), the system's power supplies are turned off
and the switch shuts down. The system remains in the OFF state until the system has sufficient time to
cool and the internal thermal sensor measures a temperature lower than the maximum specified
ambient temperature, at which time the system restarts automatically.
Alternately, you can restart the system immediately by removing and then restoring all line power to the
system.
Safeguards are built into all Extreme Networks switches and power supply units to minimize the risk of
fire.

Controlling the Humidity Level

To maximize equipment life, keep operating humidity between 50% and 70% relative humidity (non-
condensing) during typical operation.
The equipment can operate between 5% and 95% relative humidity (non-condensing) for short
intervals.
