Measures reported by IBMChassBlwrLEDTest

The BladeCenter chassis contains two hot-swap blowers for cooling redundancy. The blower speeds vary depending on the ambient air temperature at the front of the BladeCenter chassis and the temperature of core components. If the ambient temperature is 25°C (77°F) or below, the target chassis blowers run at their minimum rotational speed, increasing their speed as required to control internal temperature. If the ambient temperature is above 25°C (77°F), the blowers run faster, increasing their speed as required to control internal temperature. If the blowers stopped suddenly due to some fatal errors, the temperature of the core hardware components may suddenly soar, causing irreparable damage to those components. To avoid such failures, administrators should regularly check the availability and errors (if any) of the blowers. This is where the Blower LED test helps administrators.

This test auto-discovers the blowers on the target chassis and reports the availability and error LED status of each blower.

Outputs of the test : One set of results for each blower on the BladeCenter chassis being monitored.

Descriptor of the test : Blower

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
blowerExistense Indicates whether/not this blower exists.   The values that this measure can report and the numeric values they indicate have been listed in the table below:

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure can report the Measure Values mentioned above indicating whether each blower exists or not. However, the graph of this measure is indicated using the numeric equivalents.
blowerErrLedState Indicates the current status of the error LED of this blower.   The values that this measure can report and the numeric values they indicate have been listed in the table below:

Measure Value Numeric Value
Off 0
On 1

Note:

By default, this measure can report the Measure Values mentioned above while indicating the current status of the error LED of each blower. However, the graph of this measure is indicated using the numeric equivalents.
