Table 51. BMC Boot/Reset Status LED Indicators
BMC/Video memory test failed
Nonrecoverable condition. Contact your Intel
®
representative for information on replacing this
motherboard.
Both Universal Bootloader (u-Boot)
images bad
Nonrecoverable condition. Contact your Intel
®
representative for information on replacing this
motherboard.
Blinking green indicates degraded state (no
manageability), blinking blue indicates u-Boot
is running but has not transferred control to
BMC Linux*. Server will be in this state 6-8
seconds after BMC reset while it pulls the
Linux* image into flash.
Solid green with solid blue after an AC
cycle/BMC reset, indicates that the control has
been passed from u-Boot to BMC Linux* itself.
It will be in this state for ~10-~20 seconds.
End of BMC boot/reset process.
Normal system operation
Indicates BMC Linux* has booted and
manageability functionality is up and running.
Fault/Status LEDs operate as per usual.
10.4 Post Code Diagnostic LEDs
A bank of eight POST code diagnostic LEDs are located on the back edge of the server next to the stacked USB
connectors. During the system boot process, the BIOS executes a number of platform configuration processes,
each of which is assigned a specific hex POST code number. As each configuration routine is started, the BIOS
displays the given POST code to the POST code diagnostic LEDs. The purpose of these LEDs is to assist in
troubleshooting a system hang condition during the POST process. The diagnostic LEDs can be used to
identify the last POST process to be executed. See Appendix D for a complete description of how these LEDs
are read, and for a list of all supported POST codes.
10.5 5 Volt Stand-By Present LED
This LED is illuminated when a power cord (AC or DC) is connected to the server and the power supply is
supplying 5 Volt Stand-by power to the server board. This LED is intended as a service caution indicator to
anyone accessing the inside of the server system.
