Cooling system
The cooling system is contained within the system’s fan tray assembly and modules. The following
components comprise the cooling system:
• The FSX and FSX 800 each have six four-speed fans.
• The FSX 1600 has two five-speed fans in the rear of the chassis.
• One fan control module. The fan control module maintains the power to the fans, and controls
the fan speed and the reporting of the fan status to the management module.
• Two temperature sensors on each management module, and one temperature sensor on each
interface module
• One temperature sensor on each switch fabric module (FSX 800 and FSX 1600 only).
The fan tray in the FSX and FSX 800 chassis is located in the right side of each chassis. The FSX
1600 has two fan trays which are located in the top rear of the chassis.
Upon system startup, the fans operate at low speed, then adjust their speed based on the current
temperature of the modules and the configured temperature thresholds, or by the manually
configured fan speed.
By default, the system polls the temperature sensor on each module every 60 seconds to get a
temperature reading. (For information about changing the default temperature polling interval,
refer to “Changing the temperature polling interval” on page 95.) 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
• If the chassis exceeds the highest temperature threshold or shutdown temperature for five
minutes, the system will shut down the device to prevent damage
If the temperature of a module exceeds specified high temperature thresholds, the system
generates a Syslog message. The system can also power down the chassis if the temperature
exceeds the highest threshold.
You can change default low and high temperature thresholds for modules and fan speeds. For
more information, refer to “Changing temperature thresholds for thermal planes and fan speeds”
on page 92.
The chassis ships with all fan components fully installed in the fan tray. For information about
replacing the fan tray, refer to one of the following sections:
• “Replacing the FSX and FSX 800 fan tray” on page 151
• “Replacing the FSX 1600 fan assemblies” on page 154
• “Replacing the FSX 1600-ANR fan assemblies” on page 155
Built-in mounting brackets
The front of each FSX and FSX 800 chassis has built-in mounting brackets that enable you to
front-mount the chassis in a standard 19-inch (EIA310-D) rack. For instructions about using the
built-in mounting brackets to mount the device in a rack, refer to “Installing a chassis in a rack” on
page 48.
