10.3 BMC Boot/Reset Status LED Indicators

During the BMC boot or BMC reset process, the System Status LED and System ID LED are
used to indicate BMC boot process transitions and states. A BMC boot will occur when AC
power is first applied to the system. A BMC reset will occur after: a BMC FW update, upon
receiving a BMC cold reset command, and upon a BMC watchdog initiated reset. The following
table defines the LED states during the BMC Boot/Reset process.
BMC Boot/Reset State
BMC/Video memory test failed
Both Universal Bootloader (u-
Boot) images bad
BMC in u-Boot
BMC Booting Linux*
End of BMC boot/reset process.
Normal system operation

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
Revision 2.1
Critical, non- Fatal alarm – system has failed or shutdown:
recoverable
1. CPU CATERR signal asserted
2. MSID mismatch detected (CATERR also asserts for this case).
3. CPU 1 is missing
4. CPU ThermalTrip
5. No power good – power fault
6. DIMM failure when there is only 1 DIMM present and hence no
good memory present1.
7. Runtime memory uncorrectable error in non-redundant mode1.
8. DIMM Thermal Trip or equivalent
9. SSB Thermal Trip or equivalent
10. CPU ERR2 signal asserted
11. BMC\Video memory test failed. (Chassis ID shows blue/solid-on
for this condition)
12. Both uBoot BMC FW images are bad. (Chassis ID shows
blue/solid-on for this condition)
13. 240VA fault
Not ready AC power off

Comment
Non-recoverable condition. Contact your Intel
representative for information on replacing this motherboard.

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.
Indicates BMC Linux* has booted and manageability
functionality is up and running. Fault/Status LEDs operate
as per usual.
