4-3 Control Panel LEDs
The control panel located on the front of the SC819 chassis has up to five LEDs.
These LEDs provide critical information related to different parts of the system.
This section explains what each LED indicates when illuminated and any action
that may be required.
Universal Information LED: The Universal Information LED is used to indicate a
fan failure, power failure, overheat condition, or to identify the unit within a large
rack installation. The feature requires a motherboard that supports the 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 Identifier).
When on continuously red, it indicates an overheat condition, which may be caused
by cables obstructing the airflow in the system or the ambient room temperature
being too warm. See the table below for descriptions of the LED states.

Universal Information LED States
State Indication
Fast Blinking Red (1x/sec) Fan Fail
Solid Red CPU Overheat
Slow Blinking Red (1x/4 sec) Power Fail
Solid Blue Local UID Button Depressed
Blinking Blue IPMI-Activated UID
Note: Deactivating the UID LED must be performed in the same way it was acti-
vated. (If the UID LED was activated via IPMI, you can only turn the LED off via
IPMI and not with the UID button.)
