Hardware Monitoring and Power Management
The system features advanced hardware monitoring and power management capabilities. These
features help save energy, prolong system life, and provide for functionality such as remote system
wakeup.
When used with InterSite Hardware Monitor software, these features enable you to keep track of
such things as voltages, temperatures, and fan speeds. For more information on the items that can
be monitored on your system, refer to Hardware Monitor Help.
Resistive temperature sensors are located on the system board. These devices provide signals for
reporting temperature readout data to the InterSite Hardware Monitor software and for controlling
cooling fan speed. The temperature sensors are part of the system board and are not field
replaceable.
The Power LED on the front of the base unit indicates the following power states of the system:
If the Power LED is…
Then…
Unlit
Auxiliary power is off; there is no power consumption; the system is
disconnected from AC power
Blinking
Auxiliary power is on; power consumption is reduced
Lit
The system has full power; power conservation is per device
