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, see “Changing the Temperature
Polling Interval” on page 5-19.) 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,
see “Changing Temperature Thresholds For Thermal Planes and Fan Speeds on the FSX (pre-release 03.0.00
only), and on the FSX 1600” on page 5-10.
The chassis ships with all fan components fully installed in the fan tray. For information about replacing the fan tray,
see one of the following sections:
• “Replacing the FSX and FSX 800 Fan Tray” on page 7-29
• “Replacing the FSX 1600 Fan Assemblies” on page 7-31
• “Replacing the FSX 1600-ANR Fan Assemblies” on page 7-32
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, see “Installing a Chassis in a Rack” on page 3-5.
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 chassis in a rack.
Contact Foundry Networks for information about rack mount kits.
Layer 3 Routing Protocol Table Sizes
Use the show default values command to display Layer 3 routing protocol table sizes. The command output
shows the default, maximum, and currently configured values. See the Foundry FastIron Configuration Guide for
an example output.
