3-3 Control Panel LEDs
The control panel located on the front of the SC743S1-R760/SC743S1-650
chassis has six LEDs that provide you with critical information related to
different parts of the system. This section explains what each LED indi-
cates when illuminated and any corrective action you may need to take.
z
Power: Indicates power is being supplied to the system's power
supply. This LED should normally be on when the system is operating.
z
HDD: Indicates IDE channel activity. On the SC743S1-R760/SC743S1-
650, this LED indicates SCSI drive activity when flashing.
z
NIC1: Indicates network activity on LAN1 when flashing.
z
NIC2: Indicates network activity on LAN2 when flashing.
z
Overheat/Fan Fail: When this LED flashes, it indicates a fan failure.
When on continuously it indicates an overheat condition, which may be
caused by cables obstructing the airflow in the system or the ambient room
temperature being too warm. Check the routing of the cables and make
sure all fans are present and operating normally. You should also check to
make sure that the chassis covers are installed. Finally, verify that the
heatsinks are installed properly (see Chapter 5). This LED will remain flash-
ing or on as long as the indicated condition exists.
