Color Description
White You can turn on the Locator LED to identify a particular server
module. When on, the LED blinks rapidly. There are two methods
for turning a Locator LED on:
• Issuing the Oracle ILOM command set /SYS/LOCATE
value=Fast_Blink.
• Pressing the Locator button.
The Locator LED functions as the physical presence switch.
Blue Steady state – If LED is off, it is not safe to remove the server
module from the modular system chassis. You must use Oracle
ILOM to shut down the server module and put the blade into
ready to remove state before this LED is on.
Amber Indicates that service is required. POST and Oracle ILOM are two
diagnostics tools that can detect a fault or failure resulting in this
indication. Also, faults detected by PSH can result in Oracle
ILOM lighting this LED.
The Oracle ILOM show faulty command provides details about
any faults that cause this indicator to light.
Under some fault conditions, individual component fault LEDs
are turned on in addition to the Service Action Required LED.
Green Indicates the following conditions:
• Off – Host is not running in its normal state. Host power might
be off. The SP might be running.
• Steady on – Host is powered on and is running in its normal
operating state. No service actions are required.
• Fast blink – Host is running in standby mode and can be
quickly returned to full function.
• Slow blink – A normal, but transitory activity is taking place.
Slow blinking might indicate that diagnostics are running, or
the host is booting.
