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.

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 C for a
complete description of how these LEDs are read, and for a list of all supported POST codes.
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.
