3.3.1.2 Temperature
The
show environment temp
command displays a series of temperature thresholds for various components in a DarkStar
system, as well as the current temperature reported by each component. The temperature thresholds define the safe
operating range of each component.
The
Low Warning
and
High Warning
thresholds indicate that temperatures are moving toward levels that may cause
damage to a component, but have not yet exceeded safe levels. Warnings indicate that there might be a problem with the
component and that it should be closely monitored.
The
Low Alarm
and
High Alarm
thresholds indicate that temperatures have exceeded regular operational parameters for
that component. Continued operation at this temperature is likely to damage the component. If the component is a
replaceable part, such as a laser module, fan module, or power module, turning the component off is recommended to
prevent further damage. The component may need to be replaced.
The
Critical
threshold indicates that the component is probably already damaged and will be shut off immediately to
prevent possible damage to other DarkStar components.
In addition to the temperature sensors provided by individual components of the DarkStar system, there is a shutdown sensor
embedded in the DarkStar circuit board. If the shutdown sensor reaches 70° C, the DarkStar system will automatically power
off, disrupting switch board traffic. The DarkStar system will be unable to power on again until the sensor cools to less than
67°C.
3.3.2 Syslog
DarkStar systems can send logging information to a Syslog server.
The following example illustrates how to log messages to a Syslog server:
localhost# configure
localhost CONF# logging host ip-address-of-syslog-server
localhost CONF# exit
localhost# write memory
Are you sure? [yes/no] yes
localhost#

Temperature Thresholds
Threshold Description
Low Alarm
Temperature of system has dropped to a level that is likely to
cause damage.
Low Warning
Temperature of system is falling toward levels that may cause
damage.
High Warning
Temperature of system is rising toward levels that may cause
damage.
High Alarm
Temperature of system has risen to a level that is likely to cause
damage.
Critical
Temperature of system has exceeded safe levels and should be
shut down.
