3-3 Control Panel LEDs

action you may need to take.

Note: deactivating the UID LED must be performed in the same way it was activated.
(If the UID LED was activated via IPMI, you can only turn the LED off via IPMI and
not with the UID button.)
Universal Information LED
When this LED blinks red quickly, it indicates a fan failure and when blinking red
slowly a power failure. This 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.
