Control Panel LEDs

The control panel located on the front of th SC815TQ-R450U/SC815TQ-560U
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. 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.

IPMI and not with the UID button.)
