Environmental requirements
To ensure proper operation, the switch must not be subjected to environmental conditions
beyond those for which it was tested. The ranges specified in Table 25 list the acceptable
environment for both operating and non-operating conditions.

NOTE:
The –10 ºC to +40 ºC range applies to the ambient air temperature at the air intake
vents on the nonport side of the switch. The temperature inside the switch can be up to
75 ºC during switch operation.
If the internal temperature range exceeds the operating ranges of the components,
the LEDs, error messages, and Fabric Watch alerts will indicate a problem. Issue the
tempshow
command to view temperature status.
