Install the E4G-400 cell site aggregation router only in a temperature-controlled 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.
Note
As with all electrical equipment, Extreme Networks product lifetimes degrade with increased
temperature. If possible, temperatures should be kept at approximately 25°C (78°F) or lower.
•
Be sure that the ventilation in the installation site is adequate to maintain a temperature below 50°C
(113°F) for the E4G-400 router or below 65°C (149°F) for the E4G-200 router.
•
Install a reliable air conditioning and ventilation system for indoor locations.
•
Keep the ventilation in wiring closets running during non-business hours to prevent overheating of
the equipment.
•
Maintain an ambient operating temperature range of -10° to 50°C (14° to 122°F) for the E4G-400
router or a range of -40° to 65°C (-49° to 149°F) for the E4G-200 router.
•
Maintain a storage temperature of -40° to 70°C (-40° to 158°F).
Humidity
Keep operating humidity between 50% and 70% relative humidity (non-condensing) during typical
operation.
The equipment can operate at between 10% and 95% relative humidity (non-condensing) for short
intervals.
Spacing Requirements and Airflow
Be sure that cables and other equipment do not block the air intake or outflow on an Extreme Networks
router.
Depending on other conditions in the equipment room, it may be possible to install the routers closer to
each other; consult your Extreme Networks Customer Support representative for guidance.
Leave at least 3 inches (8 cm) of clear space in front of the air intake and outflow vents on the sides of
the router.
Airflow moves from side to side. For proper airflow through an E4G series router, leave clear space on
the left and right sides of the router.
Electrostatic Discharge (ESD)
Your system must be protected from static electricity or electrostatic discharge (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.
