• Correctable errors over a threshold of 10 and migrating to a

 

 

 

 

 

spare DIMM (memory sparing). This indicates that the user

 

 

 

 

 

no longer has spared DIMMs indicating a redundancy lost

7.3.1System Status LED – BMC Initialization

When the AC power is first applied to the system and 5V-STBY is present, the BMC controller on the server board requires 5-10 seconds to initialize. During this time, the system status LED will blink, alternating between amber and green, and the power button functionality of the control panel is disabled preventing the server from powering up.
