Upon system startup, the fans in the BigIron RX Series switches operate at high speed, then the
management module lowers the fan speed to low speed.
By default, the BigIron RX Series switch 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.
LEDs
The fan control modules include a bi-color LED, which indicates the status of the fans. Table 8
describes the LED.
