Temperature Logging
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 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
A leading cause of excessive internal heat is inadequate cooling airflow through the chassis. Maintain a 
minimum of 3 inches (76 mm) in front of all air intake and exhaust vents. The recommended clearance 
is 5 inches (127 mm). Empty chassis slots must be covered with blank panels to preserve air flow 
through the chassis.

System Impacts of Temperature Logging
The temperature logging feature does not impact the performance of the system, but temperature 
logging causes one log entry during every hour of switch operation. To prevent the loss of important 
log messages, Extreme Networks recommends the use of an external syslog server. For more 
information about the use of an external syslog server, refer to “Syslog Servers” on page 93.
Network Impact of Temperature Logging
There is no network impact due to temperature logging, because it is an internal log message option of 
the switch.
