Universal Information LED

When this LED blinks red quickly, it indicates a fan failure and when blinking red

slowly a power failure. The LED will be blue when used for UID (Unit Identiﬁ er).

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.
