System Status LED
The server board includes a bi-color System Status LED. The System Status LED on the server
board is tied directly to the System Status LED on the front panel (if present). This LED
indicates the current health of the server. Possible LED states include solid green, blinking
green, blinking amber, and solid amber.
When the server is powered down (transitions to the DC-off state or S5), the BMC is still on
standby power and retains the sensor and front panel status LED state established before the
power-down event.
When AC power is first applied to the system, the status LED turns solid amber and then
immediately changes to blinking green to indicate that the BMC is booting. If the BMC boot
process completes with no errors, the status LED will change to solid green.

Description
Green
Solid on
Ok
Indicates that the System Status is healthy. The system is not
exhibiting any errors. AC power is present and BMC has booted and
manageability functionality is up and running.
Green
~1 Hz blink
Degraded
System degraded:
1. Redundancy loss such as power-supply or fan. Applies only if the
associated platform sub-system has redundancy capabilities.
2. Fan warning or failure when the number of fully operational fans is
more than minimum number needed to cool the system.
3. Non-critical threshold crossed – Temperature (including HSBP
temp), voltage, input power to power supply, output current for main
power rail from power supply and Processor Thermal Control (Therm
Ctrl) sensors.
4. Power supply predictive failure occurred while redundant power
supply configuration was present.
5. Unable to use all of the installed memory (more than 1 DIMM
installed)
6. Correctable Errors over a threshold and migrating to a spare DIMM
(memory sparing). This indicates that the user no longer has spared
DIMMs indicating a redundancy lost condition. Corresponding DIMM
LED lit.
7. In mirrored configuration, when memory mirroring takes place and
system loses memory redundancy.
8. Battery failure.
9. BMC executing in uBoot. (Indicated by Chassis ID blinking at
Blinking at 3Hz). System in degraded state (no manageability). BMC
uBoot 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
10. BMC booting Linux*. (Indicated by Chassis ID solid ON). System
in degraded state (no manageability). Control has been passed from
BMC uBoot to BMC Linux* itself. It will be in this state for ~10-~20
seconds.
11. BMC Watchdog has reset the BMC.
12. Power Unit sensor offset for configuration error is asserted.
13. HDD HSC is off-line or degraded.
Amber
~1 Hz blink
Non-critical
Non-fatal alarm – system is likely to fail:
1. Critical threshold crossed – Voltage, temperature (including HSBP
temp), input power to power supply, output current for main power rail
from power supply and PROCHOT (Therm Ctrl) sensors.
2. VRD Hot asserted.
