Hardware features

• The FSX 1600 has two five-speed fans in the rear of the device.
• 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.
The fan tray in the FSX and FSX 800 device is located in the right side of the 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 87. 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 device 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 device 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 84.
The device 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 800 fan tray” on page 137
• “Replacing the FSX 1600 fan assemblies” on page 139
Built-in mounting brackets
The front of each FSX and FSX 800 device has built-in mounting brackets that enable you to
front-mount the device 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 the chassis in a rack”
on page 42.
Alternatively, you can use a rack mount kit (ordered separately) to center-mount the FSX and FSX
800 using two L-shaped mounting brackets. The rack mount kit comes with instructions for
installing the mounting brackets and mounting the device in a rack.
The FSX 1600 does not have built-in mounting brackets. Two brackets ship with the FSX 1600 that
enable you to front-mount or center-mount the device in a rack.
