Upon system startup, the fans in the NetIron MLX Series router operate at high speed, then the management
module lowers the fan speed to low speed.
By default, the NetIron MLX Series router polls the temperature sensor on each module every 60 seconds to get a
temperature reading. Depending on the temperature readings for the modules, the system can do the following:
•
Leave the fan speed as is
•
Increase the fan speed
•
Decrease the fan speed
•
Shut down a module to prevent damage
If the temperature of a module exceeds specified high temperature thresholds, the system generates a Syslog
message and SNMP trap. The system can also shut the module down if the temperature exceeds the highest
threshold.
You can change default low and high temperature thresholds for modules and fan speeds.
