Foundry ServerIron Hardware Installation Guide
Viewing Fan Speed Switches and Temperature Thresholds
You can view the speed at which the fans are currently operating and the configured temperature thresholds for
fan speed switching. To display the temperature of a device, enter the following command at any level of the CLI:
ServerIron>show chassis
power supply 1 ok
power supply 2 ok
power supply 1 to 2 from left to right
fan 1 ok
fan 2 ok
fan speed set to high
Current temperature : 39.0 C degrees
Warning level : 65 C degrees, shutdown level : 75 C degrees
Boot Prom MAC: 00e0.5200.0001
Syntax: show chassis
By default, the software polls the temperature sensor every 60 seconds to get the current temperature. This poll
rate is controlled by the chassis poll time, which also controls how often the software polls other system
components.
Displaying Temperature Messages
The software sends a Syslog message and an SNMP trap if the temperature crosses the warning or shutdown
thresholds. The following methods describe how to view the system log on the device. If you have configured the
device to use a Syslog server or SNMP trap receiver, see the documentation for the server or receiver.
To display the system log, enter the following command at any CLI level:
ServerIron#show log
Syslog logging: enabled (0 messages dropped, 0 flushes, 0 overruns)
Buffer logging: level ACDMEINW, 8 messages logged
level code: A=alert C=critical D=debugging M=emergency E=error
I=informational N=notification W=warning
Static Log Buffer:
Dynamic Log Buffer (50 entries):
at 0 days 0 hours 2 minutes 0 seconds, level alert
Temperature 48.0 C degrees, warning level 45.0 C degrees, shutdown level 55.0 C
degrees
at 0 days 0 hours 1 minutes 0 seconds, level alert
Temperature 50.0 C degrees, warning level 45.0 C degrees, shutdown level 55.0 C
degrees
Changing the Temperature Warning Level
The Foundry device sends a warning message whenever the device's internal temperature reaches the default or
configured warning temperature. The default warning temperature is 45o C degrees. You can change the
warning temperature using the following command.
ServerIron# temperature warning 47
Syntax: temperature warning <value>
The <value> can be 0 – 125oC.
