LED ICON Description
Temperature
LED
This Temperature LED has four distinctive states and is
linked to the two processors and a sensor on the system board.
• Steady Green for normal operation.
• Alternating Green/Red indicates the temperature has
crossed the warning threshold. If this condition continues
a system crash and possible data corruption will occur.
Must take action to correct problem.
• Steady Red indicates the temperature has exceeded the
critical threshold. If the shutdown feature is currently
enabled in HP Integrated Remote Assistant software, the
Netserver shuts down to prevent processor or system
board damage. By default, the shutdown feature is not
enabled. Refer to Chapter 10, "Configuring the HP
Netserver" to enable the shutdown feature.
• Steady Off (unlit) for power off condition.
NOTE The processors used in this HP Netserver have a thermal
sensor inside the processor package which monitors the
chip temperature. If the processor crosses the critical
threshold it shuts down operation to prevent damage to the
processor, but this may cause a system crash and possible
data corruption. The Temperature LED monitors these
two sensors and one additional sensor on the system
board.
Fan LED This Fan LED has four states of operation. The sensor
connected to this LED monitors the speed of all four fans in
the HP Netserver (including the power supply).
• Steady Green for normal fan speed operation
• Alternating Green/Red indicates one or all fans have
slowed down (crossing warning threshold). If this
condition continues a system crash and possible data
corruption will occur. Must take action to correct problem
before temperature starts to rise.
• Steady Red indicates a fan is turning slower than its
critical speed. However, this will not cause the Netserver
to shutdown.
• Steady Off (unlit) for power off condition.
