Following table describes the way to interpret these log messages.

The y values are filtered from the read sensor data. In this example the values vary in decimals,

whereas the real read sensors may change in the +/-1 range.

User can interpret the following message to know the whereabouts of the sensor driving the

new fan speeds. For e.g., as per the following log message the fan level 14 is driven by the

sensor AF on IPMP address 9a, FRU ID 0, LUN Number 0.

04:14:21.733 <debug> {ipmicooling}: New fan level 14 driven by

9a.0/0/af

(9a.0.0/af) means (IPMBAddress(9a).FruID(0).LUN(0)/SensorNumber(af))

Damage of Blades and Shelf

The default configuration used for the cooling management provides optimized cooling of

the shelf and all blades/FRUs in it. Changing the configuration may lead to poor cooling and

thus damage of the shelf and blades/FRUs in it. Therefore we strongly recommend not to

change the configuration.

If you decide to change the standard configuration, after all, then this should be done in

close coordination with your local Artesyn representative.
