Overheat/Fan Fail/UID LED
When this LED fl ashes it indicates a fan failure. When continuously on (not fl ash-
ing) 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 that all fans are present and operating
normally. Also check to make sure that the air shrouds are installed and that the
top cover is on. Finally, verify that the heatsinks are installed properly. This LED
will remain fl ashing or on as long as the fan fail or overheat condition exists. When
used with a UID-compatible motherboard, the UID function is used to turn on or off
the blue light function of the the LED. Once the blue light is activated through the
system software, the unit can be easily located in very large racks and server banks.
