Environmental requirements
Table 10 list the acceptable environment for both operating and
nonoperating conditions.
Note: The -10° to 40° Celsius 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 80° Celsius during switch operation.
If the internal temperature range exceeds the operating ranges of the
components, the LEDs, error messages, and Fabric Watch alerts indicate a
problem. Enter the tempShow or Fabric Watch commands to view
temperature status.
