• Module status LED: The module status LED is a bicolor (green/amber) indicator that shows the
current health of the module. The module status LED states are driven by the integrated platform
management subsystem. Table 16 provides a description of each supported LED state.
Table 16. Intel® D50DNP Module Status LED State Definitions
LED State Module State Module Status Description
Off No AC power to system.
• System power is not present.
• Module is in EuP Lot6 off mode.
Solid
green
Module is operating
normally.
• Module is in S5 soft-off state.
• Module is running (in S0 State) and its status is healthy. The module is not
exhibiting any errors. Source power is present, the BMC has booted, and
manageability functionality is up and running.
• After a BMC reset, and with the module ID LED solid on, the BMC is booting
Linux*. Control has been passed from BMC U-Boot to BMC Linux*. The BMC 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 more 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 sensors.
• Power supply predictive failure occurred while redundant power supply
configuration was present.
• Cannot use all installed memory (more than 1 memory module installed).
• Correctable errors over a threshold and migrating to a spare memory module
(memory sparing). This situation indicates that the module no longer has spare
memory modules (a redundancy lost condition).
• In mirrored configuration, when memory mirroring takes place and the module
loses memory redundancy.
• Battery failure.
• BMC executing in U-Boot (this is indicated by module ID LED blinking at 3 Hz
while status blinking at 1 Hz). Module is in degraded state (no manageability).
BMC U-Boot is running but has not transferred control to BMC Linux*. The
module is in this state 6–8 seconds after BMC reset while it pulls the Linux* image
from 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 sensors.
• VRD hot asserted.
• Minimum number of fans to cool the system not present.
• 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 or firmware update.
