Item Description
1 Temperature attention
2 Hot-plug fan 1 attention
3 Hot-plug fan 2 attention
4 Processor board 1 attention
5 Processor board 2 attention
The temperature attention LED has two possible states:
• Amber LED—The first temperature threshold has been reached. Fans are at high
speed. If the server location is at a normal temperature, check the health driver to
determine which sensor has tripped, and check the server to see if action is
necessary.
• Red LED—The server is off because it reached an overtemperature state on one
of its sensors, and shut down to protect hardware. Check the health driver or
Insight Manager to determine which thermal sensor shut down.
