Extreme Networks ExtremeSwitching VSP 7400 Series User Manual

•
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 on page 71 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 o
and the switch shuts down. The system remains in the OFF state until the system has sucient 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.
Protecting Your System from ESD (Electrostatic Discharge)
Your system must be protected from static electricity or ESD. Take the following measures to ensure
optimum system performance:
•
Remove materials that can cause electrostatic generation (such as synthetic resins) from the wiring
closet.
Check the appropriateness of floor mats and flooring.
•
Connect metal chassis, conduit, and other metals to ground using dedicated grounding lines.
•
Use electrostatically safe equipment.
If you are working with pluggable interface modules, wear an ESD-preventive wrist strap and
connect the metal end to a grounded equipment rack or other source of ground.
Rack Specifications and Recommendations
Racks should conform to conventional standards.
In the United States, use EIA Standard RS-310C: Racks, Panels, and Associated Equipment. In countries
other than the United States, use IEC Standard 297. In addition, verify that your rack meets the basic
mechanical, space, and earthquake requirements that are described in this section.
