10.1
System ID LED
The server board includes a blue system ID LED which is used to visually identify a specific server installed
among many other similar servers. There are two options available for illuminating the System ID LED.
1. The front panel ID LED Button is pushed, which causes the LED to illuminate to a solid on state until
the button is pushed again.
2. An IPMI “Chassis Identify” command is remotely entered, which causes the LED to blink
The System ID LED on the server board is tied directly to the System ID LED on system front panel if present.
10.2
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
Off

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.

~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 sparing). 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.
