F – System Status LED – The System Status LED is a bi-color (Green/Amber) indicator that shows the
current health of the server system. The system provides two locations for this feature; one is located on the
Front Control Panel, the other is located on the back edge of the server board, viewable from the back of the
system. Both LEDs are tied together and will show the same state. The System Status LED states are driven
by the on-board platform management sub-system. The following table provides a description of each
supported LED state.

Description
Off
System is not
operating
Not ready
1. System is powered off (AC and/or DC).
2. System is in EuP Lot6 Off Mode.
3. System is in S5 Soft-Off State.
4. System is in S4 Hibernate Sleep State.
Green
Solid on
Ok
Indicates that the System is running (in S0 State) and its 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
is operating in a
degraded state
although still
functional, or
system is operating
in
a redundant state
but with an
impending failure
warning
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 suppl
y predictive failure occurred while redundant power supply
configuration was present.
5. Unable to use all of the installed memory (one or more DIMMs
failed/disabled but functional memory remains available)
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. Uncorrectable memory error has occurred in memory Mirroring Mode,
causing Loss of Redundancy.
8. Correctable memory error threshold has been reached for a failing
DDR3 DIMM when the system is operating in fully redundant RAS
Mirroring Mode.
9. Battery failure.
10. 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
11. 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.
12. BMC Watchdog has reset the BMC.
13. Power Unit sensor offset for configuration error is asserted.
14. HDD HSC is off-line or degraded.
Amber
~1 Hz blink
Non-critical -
System is operating
in a degraded state
with an impending
failure warning,
although still
functioning
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.
3. Minimum number of fans to cool the system not present or failed
4. Hard drive fault
5. Power Unit Redundancy sensor – Insufficient resources offset
(indicates not enough power supplies present)
6. In non-sparing and non-mirroring mode if the threshold of correctable
errors is crossed within the window
7. Correctable memory error threshold has been reached for a failing
DDR3 DIMM when the system is operating in a non-redundant mode
