Features
Temperature / system monitoring
Fan control
The fans are regulated according to temperature.
Sensor monitoring
The removal of, or a fault in, a temperature sensor is detected. Should this
happen all fans monitored by this sensor run at maximum speed, to achieve the
greatest possible protection of the hardware.
Voltage monitoring
When voltage exceeds warning level high or falls below warning level low an
alert will be generated.
Cover monitoring
Unauthorized opening of the cover is detected, even when the system is
switched off. However, this will only be indicated when the system is switched
on again.
System Event Log (SEL)
All monitored events of the system board are signalized via the Global Error
LED and recorded in the System Event Log. They could be retrieved in the BIOS
Setup or via ServerView.
PRIMERGY Diagnostic LEDs
Optical signaling through the LEDs on the system board identifies defective
modules and components as well as gaining information on the PDA.
