Control Panel LEDs

Power Fail
Indicates a power supply module has failed. The second power supply module will
take the load and keep the system running but the failed module will need to be
replaced. Refer to Chapter 6 for details on replacing the power supply. This LED
should be off when the system is operating normally.
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.
See the table below for descriptions of the LED states.
