temperature-threshold
Specifies a temperature threshold for the module. The
range is 0° C to 75° C (32° F to 167° F). 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 97.
Privilege Levels
Administrator and read-write.
Description
This command assigns a name and temperature threshold to a module.
Assigning a name to a module can make it easier for you to identify it.
Only the management and media converter modules support names. All
modules, including power supply and fan modules, support temperature
thresholds. To view module names, refer to “SYSTEM SHOW
INTERFACE” on page 90, “SYSTEM SHOW CHASSIS” on page 86 or
“SYSTEM SHOW CLUSTER” on page 88.
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 97.
The operating temperatures of the modules in a chassis can vary widely
depending on their proximity to the cooling fans and the area on the
module where the temperature is measured. This should be taken into
consideration when setting a temperature threshold for a module. For the
power supply and fan modules, 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.
