3-3 Control Panel LEDs
The control panel located on the front of the SC743TQ-645 chassis has six LEDs
that provide you with critical information related to different parts of the system.
This section explains what each LED indicates when illuminated and any corrective
action you may need to take.
Power: Indicates external power is being supplied to the system's power
supply unit. This LED should normally be illuminated when the system is operat-
ing.
HDD: Indicates IDE channel activity. On the 7045A-3, this LED indicates
SAS/SATA/IDE drive activity when fl ashing.
NIC: Indicates network activity on LAN1 when fl ashing.
NIC: Indicates network activity on LAN2 when fl ashing
Overheat: When this LED fl ashes, it indicates a fan failure. When on
continuously it indicates an overheat condition, which may be caused by cables
obstructing the airfl ow 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 fl ashing or on as long as the indicated condition exists.
