Table 65. System status LED state definitions
LED State
System State
BIOS Status Description
Off
System is not operating.
System AC power is off.
System is in EuP Lot6 off mode.
System is in S5 soft-off state.
Solid green
System is operating normally.
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.
After a BMC reset, and in conjunction with the chassis ID solid on, the BMC is
booting Linux*. Control has been passed from BMC uBoot to BMC Linux*
itself. It is in this state for roughly 10-20 seconds.
Blinking green
System is operating in a
degraded state although still
functioning, or system is
operating in a redundant
state but with an impending
failure warning.
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 less than
the 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 (more than 1 DIMM installed).
Correctable Errors over a threshold and migrating to a spare DIMM (memory
sparing). This indicates that the system no longer has spared DIMMs (a
redundancy lost condition). Corresponding DIMM LED lit.
In mirrored configuration, when memory mirroring takes place and system
loses memory redundancy.
Battery failure.
BMC executing in uBoot. (Indicated by Chassis ID 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 Watchdog has reset the BMC.
Power Unit sensor offset for configuration error is asserted.
HDD HSC is off-line or degraded.
Blinking amber System is operating in a
degraded state with an
impending failure warning,
although still functioning.
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.
