This chapter provides instructions for maintaining the FastIron LS.
WARNING: The procedures in this manual are for qualified service personnel.
This chapter contains the following information:
Managing FastIron LS Temperature Settings
This section describes how to display temperature settings on the FastIron LS and how to change the temperature
warning and shutdown levels.
Using the Temperature Sensor on the FastIron LS
The FastIron LS comes with a built-in temperature sensor. The temperature sensor causes the device to generate
a Syslog message and SNMP trap if the temperature exceeds a specified warning level or shutdown level. If the
device’s temperature exceeds the safe threshold (shutdown level), the device will reboot if it stays in the safe
threshold for five minutes.
The software reads the temperature sensor according to the device poll time, which is 60 seconds by default. If
the temperature equals or exceeds the shutdown temperature for five consecutive polls of the temperature by the
software, the software will reboot the device to prevent damage.
