Both universal bootloader
(u-Boot) images bad
6 Hz blinking
blue
Solid amber
Non-recoverable condition. Contact an Intel representative for
information on replacing this motherboard.
BMC in u-Boot
3 Hz blinking
blue
1 Hz blinking
green
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.
BMC booting Linux*
Solid blue
Solid green
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
Off
Solid green
Indicates BMC Linux* has booted and manageability functionality is
up and running. Fault/status LEDs operate as per usual.

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 (see Figure 70). 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 B for a complete
description of how these LEDs are read, and for a list of all supported POST codes
9.5
Fan Fault LEDs
The server board includes a fan fault LED next to each of the six system fans (see Figure 70). The LED has two
states: on and off. The BMC lights a fan fault LED if the associated fan-tach sensor has a lower critical
threshold event status asserted. Fan-tach sensors are manual re-arm sensors. Once the lower critical
threshold is crossed, the LED remains lit until the sensor is rearmed. These sensors are rearmed at system
DC power-on and system reset.
9.6
Memory Fault LEDs
The server board includes a memory fault LED for each DIMM slot (see Figure 71). When the BIOS detects a
memory fault condition, it sends an IPMI OEM command (Set Fault Indication) to the BMC to instruct the BMC
to turn on the associated memory slot fault LED. These LEDs are only active when the system is in the on
state. The BMC does not activate or change the state of the LEDs unless instructed by the BIOS.
9.7
CPU Fault LEDs
The server board includes a CPU fault LED for each CPU socket. The CPU fault LED is lit if there is an MSID
mismatch error is detected (that is, CPU power rating is incompatible with the board).
