threshold for the high speed, the router shuts down the modules to prevent damage. The router also sends a warning message
to the system log and an SNMP trap. For information about viewing the warning messages, refer to Displaying temperature
warnings on page 218.
• The frequency with which the temperature is checked is determined by the setting of the temp-poll-period command. For
information about temp-poll-period command, refer to Changing the temperature polling interval on page 216.
• If the temperature of a management module, switch fabric module, and interface modules falls below the low threshold for a fan
speed, the fan changes to the next lower speed. If the temperature of all modules falls below the high threshold for the low
speed, the fan operates at the low speed.
Default temperature thresholds for Brocade NetIron MLX Seriesdevices are described in the following table.
