Intel® Server Board S3420GP TPS
9. Intel Light Guided Diagnostics
®
The server board has several on-board diagnostic LEDs to assist in troubleshooting board-level
issues. This section shows where each LED is located on the server board and describes the
function of each LED.
9.1 System Status LED (For the Intel
S3420GPLC)
The server board provides 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 60. Front Panel Status LED Behavior Summary

Criticality
Not ready AC power off. If no degraded, non-critical, critical, or non-
recoverable conditions exist.
Fatal alarm – system has failed or shutdown:
Critical, non-
recoverable 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.
Uncorrectable memory error.
Non-fatal alarm – system is likely to fail:
Non-critical
CATERR asserted.
Critical temperature threshold asserted.
Critical voltage threshold asserted.
Critical fan threshold asserted.
VRD hot asserted.
SMI Timeout asserted.
Correctable error threshold has been reached for a failing DDR3
DIMM.
System booted and ready.
System OK
System degraded:
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.
Unable to use all of the installed memory (more than one DDR3
DIMM installed).
Correctable error threshold has been reached for a failing DDR3
DIMM on a given channel.
