ERROR LED
The Baseboard Management Controller (BMC), an onboard management
controller of the system unit, turns on the ERROR LED on the front of the system
unit if a hardware error occurs, such as a HDD error, a fan error, a power supply
error, and others.
The sensors having a threshold are lit up in the Critical State (a critical state of
the system unit). But do not turn on in the Uncritical State (a state in which a
component has a failure under redundancy).
MAINTENANCE LEDs
You can choose what is displayed as the operation status from the event code,
the POST code and the power consumption using a SERVICE switch.
A combination of ON/OFF selections of MODE0 LED, MODE1 LED, and SERVICE
LED determines what is currently displayed.
