Control Panel LEDs
The control panel located on the front of the SC815TS-R560U/SC815TS-560UBP
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.
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.
