Description
This Alert keeps track of the system temperature and detects when the enclosure temperature has exceeded the threshold.
The system or component temperature is being measured by temperature sensors inside the system. If the system or component temperature changes with respect to a manufacturer-defined or user-defined threshold, an event occurs. All temperature sensors should always be within the specified range.
Enclosure temperature is also monitored and managed by BMC (Baseboard Management Controller), and out-of-range temperature is reported through the logs in the BMC or RSA-II (Remote Supervisor Adapter). To ensure proper operations, keep the firmware and the device driver current. See the "Additional information" section below for the download location.
Causes
These are some conditions that can influence the enclosure temperature:
"
The airflow is obstructed.
"
The environmental cooling capacity is insufficient.
"
The power supply does not work.
"
A fan is malfunctioning.
Implications
Power consumption and heat output vary depending on the number and type of optional features installed. Address the enclosure temperature as soon as possible. If the enclosure temperature keep rising, the system might shut down by itself.
Resolutions
1. If possible, shut down the system and check the environmental cooling capacity.
2. Gather all the available information about your Alert.
"
Consult the Hardware Maintenance manual and Troubleshooting Guide.
"
Retain the full logs recorded by the systems management software (such as IBM Director Server). Information in the logs such as the instance ID (or Device ID), when available, can help you to identify the particular component that experienced the problem.
3. Place a service call.
NOTE: To reduce the risk of electric shock or fire, shut down the system first. Do not attempt to service the system yourself. Refer all servicing to qualified service personnel.
