Table 7. Intel® D50TNP Module Status LED State Definitions
LED State
Module State
BIOS Status Description
Off
No AC Power to system
•
System power is not present.
•
Module is in EuP Lot6 off mode.
•
Module is in S5 soft-off state.
Solid
green
Module is operating
normally.
•
Module is running (in S0 State) and its status is healthy. The module is not
exhibiting any errors. Source power is present BMC has booted and
manageability functionality is up and running.
•
After a BMC reset, and in conjunction with the module ID LED solid on, the BMC
is booting Linux*. Control has been passed from BMC uBoot to BMC Linux*. It is
in this state for roughly 10
–
20 seconds.
Blinking
green
Module is operating in a
degraded state although
still functioning, or
module 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 subsystem 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, 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 installed memory (more than 1 DIMM installed).
•
Correctable Errors over a threshold and migrating to a spare DIMM (memory
sparing). This indicates that the module no longer has spared DIMMs (a
redundancy lost condition).
•
In mirrored configuration, when memory mirroring takes place and the module
loses memory redundancy.
•
Battery failure.
•
BMC executing in uBoot. (Indicated by module ID LED blinking at 3 Hz while
Status blinking at 1 Hz). Module in degraded state (no manageability). BMC
uBoot is running but has not transferred control to BMC Linux*. The module 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.
•
SSD Hot Swap Controller (HSC) is off-line or degraded.
Module is initializing after
AC power is applied
•
PFR in the process of updating/authenticating/recovering when AC power is
connected, module firmware being updated.
•
Module not ready to take power button event/signal.
Blinking
amber
Module is operating in a
degraded state with an
impending failure
warning, although still
functioning. Module is
likely to fail.
•
Critical threshold crossed
–
Voltage, temperature, 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.
•
Storage 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.
•
Invalid firmware image detected during boot up or firmware update.
