The LEDs are controlled by the BMC, but the BIOS informs the BMC of the memory errors that
are described in the table. The methods used to inform the BMC of the error(s) are described
section
3.3.10.2.1. It is the responsibility of the BMC to modify the LED behavior according to
the notification received from the BIOS.
3.3.10.2.4.1 System Status LED – BMC Initialization
When the AC power is first applied to the system and 5 V standby is present, the BMC controller
on the server board requires 15-20 seconds to initialize. During this time, the system status LED
blinks, alternating between amber and green, and the power button on the control panel is
disabled, preventing the server from powering up. After BMC initialization has completed, the
status LED will stop blinking and the power button functionality is restored.
3.3.10.2.5 NMI Generation
The BIOS will generate an NMI to halt the system progress when normal memory operations
cannot continue. The following table lists the conditions under which NMI generation occurs.
Table 8. NMI Generation
Error Event Mode of Operation

or sparing mode or mirroring mode when the primary
