The BIOS detects these conditions and sends a Set Fault Indication command to the Integrated BMC to provide the contribution to the system status LED. 2. Support for upper non-critical limit is not provided in the default SDR configuration. However, if a user does enable this threshold in the SDR, then the system status LED should behave as described. There is no precedence or lock-out mechanism for the control sources. When a new request arrives, all previous requests are terminated. For example, if the chassis ID LED is blinking and the chassis ID button is pressed, then the chassis ID LED changes to solid on. If the button is pressed again with no intervening commands, the chassis ID LED turns off. 106 Revision 2.0 Intel order number G13326-004

System Status Indicator LED
The Intel
®
Server Board S1200BTL has a system status indicator LED on the front panel. This
indicator LED has specific states and corresponding interpretation as shown in the
following table.
Table 28. System Status LED Indicator States
Color
State
Criticality
Description
Green
Solid on
Ok
System booted and ready
Green
~1 Hz blink
Degraded
System degraded:
Non-critical temperature threshold asserted.
Non-critical voltage threshold asserted.
Non-critical fan threshold asserted.
Fan redundancy lost, sufficient system cooling maintained. This does
not apply to non-redundant systems.
Power supply predictive failure.
Power supply redundancy lost. This does not apply to non-redundant
systems.
Correctable errors over a threshold of 10 and migrating to a spare
DIMM (memory sparing). This indicates the user no longer has
spared DIMMs indicating a redundancy lost condition. Corresponding
DIMM LED should light up 4.
Amber
~1 Hz blink
Non-critical
Non-fatal alarm
–
system is likely to fail:
CATERR asserted.
Critical temperature threshold asserted.
Critical voltage threshold asserted.
Critical fan threshold asserted.
VRD hot asserted.
SMI Timeout asserted.
Amber
Solid on
Critical, non-
recoverable
Fatal alarm
–
system has failed or shutdown:
Thermtrip asserted.
Non-recoverable temperature threshold asserted.
Non-recoverable voltage threshold asserted.
Power fault/Power Control Failure.
Fan redundancy lost, insufficient system cooling. This does not apply
to non-redundant systems.
Off
N/A
Not ready
AC power off, if no degraded, non-critical, critical, or non-recoverable
conditions exist.
Notes:
1.
The BIOS detects these conditions and sends a Set Fault Indication command to the Integrated BMC to provide
the contribution to the system status LED.
2.
Support for upper non-critical limit is not provided in the default SDR configuration. However, if a user does
enable this threshold in the SDR, then the system status LED should behave as described
.
There is no precedence or lock-out mechanism for the control sources. When a new request
arrives, all previous requests are terminated. For example, if the chassis ID LED is blinking and
the chassis ID button is pressed, then the chassis ID LED changes to solid on. If the button is
pressed again with no intervening commands, the chassis ID LED turns off.
