4.3 STATUS INDICATORS
The PIP provides 13 status indicator LEDs, giving you visual information about the actual operating status.
4.3.1 POWER INDICATOR LED
The power indicator LED lights green if the system has started and is under power, it lights yellow if the PIP is in
S5 state (Soft Off) or blinks green if the system is in S3 State (suspend to RAM).
When the CPU temperature is above 100 °C this LED blinks green/yellow and above 125 °C the PIP
immediately shuts down to S5 state and the LED lights yellow.
After an overtemperature shutdown you have to press the power button for starting the PIP again. A power cycle
only does not work.
4.3.2 RESET INDICATOR LED
The red reset indicator LED lights if the PIP is in reset state and blinks if the system is in a power fail state.
In a power fail state please remove the power cord and all the additional connections from the PIP. Then try to
power the solely PIP again.
4.3.3 HDD INDICATOR LED
The green HDD indicator LED lights whenever an IDE or SATA device is accessed.
4.3.4 IEEE1394b INDICATOR LED
The yellow FireWire IEEE1394b indicator lights whenever a FireWire device is connected.
4.3.5 LAN 1 Activity INDICATOR LED
The green LAN 1 activity indicator lights whenever a link is detected. The LED blinks if network activity is
detected.
4.3.6 LAN 1 Speed INDICATOR LED
The LAN 1 speed indicator lights green whenever a 100 MBit/s link is detected and lights yellow when a GBit/s
link is detected. For 10 MBit/s it remains dark.
