Temperature Logging for Modular Switches
One of the leading causes of early failure in all electrical equipment is excessive heat. To achieve
maximum service life for equipment, adhere to the recommended environmental requirements for the
equipment. The ExtremeWare temperature-logging feature for modular switches aids in maintaining
optimum operating conditions by reporting the internal operating temperature (celsius) of a switch once
an hour to both the internal system log and to a syslog server, if configured.
The recommended ambient operating temperature for Extreme Networks switches is 32° to 104° F (0° to
40° C), but this range represents the absolute limits of the equipment. Whenever possible, the
temperature should be kept at approximately 78° F (25° C). Operating humidity should be kept between
10 and 95% relative humidity. For more information, refer to the Consolidated Hardware Installation Guide.
NOTE
Inadequate cooling airflow through the chassis causes excessive internal heat. Maintain at least
3 inches (76 mm) in front of all air intake and exhaust vents. The recommended clearance is 5 inches
(127 mm). Empty slots must be covered with blank panels to preserve air flow within the chassis.
