HP Modular Cooling System manual Sensors Water group sensor Snmp notification Type of message

Solution:

1.View the Overview menu to distinguish which temperature sensor is different from the other temperature sensors.

2.After discovering which temperature sensor is not working properly, remove that module and reinstall it. If the difference is in the Server Exhaust Temperature, replace the appropriate fan unit. If the difference is in the Server Intake Temperature, replace the appropriate HEX unit.

If the warning message does not clear after the module is reseated, replace the HEX unit with a CSR part. For more information on CSR parts, see "Replaceable parts and maintenance and service information (on page 63)."
