NOTE
After a power supply is removed from a ServerIron ADX 4000, ServerIron ADX 8000 or ServerIron
ADX 10000 chassis, the software determines if there is enough power to power-on the interface
modules. If it determines that there is not enough power, some interface modules are powered off.
Cooling systems
Upon system startup, the fans in ServerIron ADX run at medium speed, and the speed is changed
to low. The fans switch to high speed only if the temperature sensors detect a need for additional
cooling.
By default, ServerIron ADX 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 exceeds specified high temperature thresholds, the system generates a syslog
message and Simple Network Management Protocol (SNMP) trap. The system can also shut a
module down if the temperature exceeds the highest threshold. You can change default low and
high temperature thresholds for modules and fan speeds through software.
ServerIron ADX 1000 and ServerIron ADX 1000F cooling system
The ServerIron ADX 1000 and ServerIron ADX 1000F are equipped with a fan tray containing
variable-speed fans and fan controllers.
