HP Integrated Lights-Out 3 - Manual (Page 101)

The Temperature Information page table displays the following information:
•
Temp—The ID of the temperature sensor.
•
Location—The area where the temperature is being measured.
In this column, Memory refers to the following:
◦ Temperature sensors located on physical memory DIMMs.
◦ Temperature sensors located close to the memory DIMMs, but not located on the DIMMs.
These sensors are located further down the airflow cooling path, near the DIMMs, to
provide additional temperature information.
•
Status—The temperature status. Depending on the server configuration, some sensors show
a status of Not installed.
•
Reading—The temperature recorded by the listed temperature sensor. If a temperature sensor
is not installed, the Reading column shows the value N/A.
•
Thresholds—The temperature thresholds for the warning for overheating conditions. The two
threshold values are Caution and Critical. If a temperature sensor is not installed, the Thresholds
column shows the value N/A.
◦ Caution—The server is designed to maintain a temperature below the caution threshold
while operating. If a failure prevents the server from maintaining this temperature, the
server increases the fan speed and initiates a graceful operating system shutdown. This
ensures both data integrity and system safety.
◦ Critical—If temperatures are uncontrollable or rise quickly, the critical temperature threshold
prevents system failure by physically shutting down the system before the high temperature
causes an electronic component failure.
Viewing power information
iLO monitors the power supplies in the server to ensure the longest available uptime of the server
and operating system. Power supplies might be affected by brownouts and other electrical
conditions, or AC cords might be unplugged accidentally. These conditions result in a loss of
redundancy if redundant power supplies are configured, or result in a loss of operation if redundant
power supplies are not in use. If a power supply failure is detected (hardware failure) or the AC
power cord is disconnected, events are recorded in the IML and LED indicators are used.
If the server is powered off, the system health information on this page is current as of the last
power off. Health information is updated only when the server is powered on and POST is complete.
To view power information, navigate to the Information
→System Information page, and then click
the Power tab, as shown in Figure 48 (page 102) .
