Table 49. System Status LED State Definitions

Criticality
Ok Indicates that the System 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.
Degraded System degraded:
1. Redundancy loss such as power-supply or fan. Applies only if the
associated platform sub-system has redundancy capabilities.
2. Fan warning or failure when the number of fully operational fans is
more than minimum number needed to cool the system.
3. 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.
4. Power supply predictive failure occurred while redundant power
supply configuration was present.
5. Unable to use all of the installed memory (more than 1 DIMM
installed)
6. 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.
7. In mirrored configuration, when memory mirroring takes place and
system loses memory redundancy.
8. Battery failure.
9. 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
10. 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.
11. BMC Watchdog has reset the BMC.
12. Power Unit sensor offset for configuration error is asserted.
13. HDD HSC is off-line or degraded.
Non-critical Non-fatal alarm – system is likely to fail:
1. 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.
2. VRD Hot asserted.
3. Minimum number of fans to cool the system not present or failed
4. Hard drive fault
5. Power Unit Redundancy sensor – Insufficient resources offset
(indicates not enough power supplies present)
6. In non-sparing and non-mirroring mode if the threshold of
correctable errors is crossed within the window1
