Intel® Server Board M50CYP2SB Family Technical Product Specification
93
Note:
In an Intel Server System M50CYP2UR or M50CYP1UR family, the system status LED on the server
board is tied directly to the system status LED on the front panel.
The following table lists and describes the states of the system status LED.
Table 42. System Status LED State Definitions
LED State
System State
BIOS Status Description
Off
No AC Power to system
•
System power is not present.
•
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. Source power is present, 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*. The BMC 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 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 (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 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 3 Hz while
Status blinking at 1 Hz). 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.
•
SSD Hot Swap Controller is off-line or degraded.
System is initializing
after source power is
applied
•
PFR in the process of updating/authenticating/recovering when source
power is connected. system firmware being updated.
•
System not ready to take power button event/signal.
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.
•
Invalid firmware image detected during boot up or firmware update
