NOTE
The -10° to 40° Celsius range applies to the ambient air temperature at the air intake vents on the non-
port 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.
