6.4.3 NMI Button
The Intel
®
S3420GPRX Server Board family BIOS does not support the NMI button.
6.4.4 System Status Indicator LED
The Intel
®
Server Board S3420GPRX that uses the Intel
®
Xeon
®
3400 Series processor 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 51. 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.
1
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
