3-3 Control Panel LEDs
The control panel located on the front of the SC818A-1400B chassis has fi ve LEDs.
These LEDs 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.
Overheat/Fan Fail
When this LED fl ashes it indicates a fan failure. When on continuously (on and not
fl ashing) it indicates an overheat condition, which may be caused by cables ob-
structing 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

Finally, verify that the heatsinks are installed properly (see Chapter 5). This LED
will remain fl ashing or on as long as the overheat condition exists.
