Extreme Networks VSP 4900 Series User Manual

• Use a vinyl oor covering in your wiring closet. (Concrete oors accumulate dust, and
carpets can cause static electricity.)
• Prevent unauthorized access to wiring closets by providing door locks. Install the
equipment in a secured, enclosed, and restricted access location, ensuring that only
qualied service personnel have access to the equipment.
• Provide adequate overhead lighting for easy maintenance.
• 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
Consult an electrical contractor for commercial building and wiring
specications.
Controlling the Temperature
Extreme Networks equipment generates a signicant 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 re. Too little humidity can produce electrical shock and re.
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 congurations support higher
operating temperatures. See Environmental Data in "Technical Specications" 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 sufcient time to cool and the internal thermal sensor
measures a temperature lower than the maximum specied 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 re.
