page 101.
temperature-threshold
Specifies a temperature threshold in the range of 0° C to
75° C (32° F to 167° F) for a module. The default value is
60° C. The management module logs an event in the event
log if a module’s temperature exceeds the threshold or if,
after exceeding it, falls below it. Different modules in the
same chassis can have different temperature thresholds.
To view a module’s current temperature threshold value,
refer to “SYSTEM SHOW MODULE” on page 111.
Privilege Levels
Administrator and read-write.
Description
This command is used to assign a name and a temperature threshold to a
module. Names can make identifying the modules easier. Only the
management and media converter modules support names. All of the
modules, including the power supply and fan modules, support
temperature thresholds. To view the module names, refer to “SYSTEM
SHOW INTERFACE” on page 103, “SYSTEM SHOW CHASSIS” on
page 99 or “SYSTEM SHOW CLUSTER” on page 101.
The operating temperature of the modules in a chassis can be monitored
with the temperature threshold parameter. The management module logs
an event in the event log if a module’s temperature exceeds or falls below
the threshold. All of the modules, with the exception of the AT-MCF2000S
Stacking Module, support a temperature threshold. To view a module’s
current temperature threshold value, refer to “SYSTEM SHOW MODULE”
on page 111.
The operating temperatures in a chassis can vary widely depending on the
proximity of the modules to the cooling fans and the areas on the modules
where the temperatures are measured. This should be taken into
consideration when setting a temperature threshold for a module. For a
power supply or fan module, the temperature is measured where the
outside air enters the cooling vents on the module. Consequently, these
modules tend to measure the ambient temperature of the room or wiring
closet where the chassis is installed. In contrast, the temperatures for the
management and media converter modules are measured on the circuit
board away from the cooling vents, and so typically reflect the internal
temperature of the chassis.
