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 LED indicator lights green if the system has started and is under power. If the System is in Soft Off
(S5) mode this LED lights yellow. In S3 State (suspend to RAM) this LED blinks green.
If the CPU temperature is above 100 °C this LED blinks green/yellow. If the CPU temperature is above 125 °C
the PIP shuts down to Soft Off (S5) immediately, and this LED lights yellow.
4.3.2 RESET INDICATOR LED
The red reset LED lights if the PIP is in reset state. If this LED is blinking the system is in power-fail state. This
means the power supply was overloaded or a short circuit has occurred. In this case the power supply switches
off to protect itself.
After removing of the overload or the short circuit cause, you can restart the power supply by cycling the power
to the PIP or by pushing the Power Button twice, first for about 4 seconds until the PIP goes to Soft Off state
and second for a short time until the PIP starts normally.
4.3.3 HDD INDICATOR LED
The green HDD access indicator 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.
4.3.7 USER1, USER2 INDICATOR LEDS
The yellow USER1 and USER2 LEDs are programmable, please refer to the chapter 5.1.4 for more information.
