Using The Temperature Sensor; Displaying The Temperature - HP ProCurve 9304M Installation And Configuration Manual

Installation and Basic Configuration Guide

Using the Temperature Sensor

The following products and modules have a temperature sensor:
• T-Flow Redundant Management Module
• Management Modules 2 and 4
The redundant management modules contain a temperature sensor. The temperature sensor generates a Syslog
message and SNMP trap if the temperature exceeds a specified warning level or shutdown level, and can shut the
module down if the temperature exceeds the safe threshold. You can use the CLI or Web management interface
to display the temperature and to change the warning and shutdown temperature levels. The software reads the
temperature sensor according to the chassis 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 shuts down the module to prevent damage.
You can display the temperature of the module. You also can change the warning and shutdown temperatures
and the chassis poll time.

Displaying the Temperature

By default, the software polls the temperature sensor on the module 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. You can display the temperature of the module using either of the following methods.
USING THE CLI
To display the temperature of a module, enter the following command at any level of the CLI:
HP9300> show chassis
power supply 1 not present
power supply 2 not present
power supply 3 ok
power supply 4 not present
power supply 1 to 4 from bottom to top
fan 1 ok
fan 2 bad
fan 3 ok
fan 4 ok
Current temperature : 34.5 C degrees
Warning level : 45 C degrees, shutdown level : 55 C degrees
Syntax: show chassis
USING THE WEB MANAGEMENT INTERFACE
1. Log on to the device using a valid user name and password for read-write access. The System configuration
dialog is displayed.
2. Click on the plus sign next to Monitor in the tree view to display the monitoring options.
3. Select the Device link to display the Device Information panel. The temperature is listed in the Temperature
field. The temperature information is color coded to indicate the state.
• Green indicates the temperature is within the normal operating range.
• Orange indicates the temperature has reached the warning level.
• Red indicates the temperature has reached the shutdown level.
NOTE: You also can display the Device Information panel by clicking on the graphic of the chassis panel, in the
upper right frame. The graphic is shown only if the Web management interface frames are enabled.
