8.2.1.6 Hard Drive Activity LED Support
The drive activity LED on the front panel indicates drive activity from the on-board hard disk controllers. The
server board also provides a header giving access to this LED for add-in controllers.
8.2.1.7 System Status LED Support
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:
Redundancy loss, such as power-supply or fan. Applies only if the
associated platform sub-system has redundancy capabilities.
Fan warning or failure when the number of fully operational fans is more
than minimum number needed to cool the system.
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.
Power supply predictive failure occurred while redundant power supply
configuration was present.
Unable to use all of the installed memory (one or more DIMMs
failed/disabled but functional memory remains available)
Correctable Errors over a threshold and migrating to a spare DIMM
(memory s
paring). This indicates that the user no longer has spared DIMMs
indicating a redundancy lost condition. Corresponding DIMM LED lit.
Uncorrectable memory error has occurred in memory Mirroring Mode,
causing Loss of Redundancy.
Correctable memory error threshold has been reached for a failing DDR3
DIMM when the system is operating in fully redundant RAS Mirroring Mode.
Battery failure.
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
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.
BMC Watchdog has reset the BMC.
Power Unit sensor offset for configuration error is asserted.
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:
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.
VRD Hot asserted.
Minimum number of fans to cool the system not present or failed
Hard drive fault
Power Unit Redundancy sensor – Insufficient resources offset (indicates not
enough power supplies present)
In non-sparing and non-mirroring mode if the threshold of correctable errors
is crossed within the window
Correctable memory error threshold has been reached for a failing DDR3
DIMM when the system is operating in a non-redundant mode
