Intel® Server Boards S5520HC, S5500HCV, and S5520HCT TPS Intel® Light Guided Diagnostics • By issuing the appropriate hex IPMI "Chassis Identify" value, the ID LED will either blink blue for 15 seconds and turn off or will blink indefinitely until the appropriate hex IPMI Chassis Identify value is issue to turn it off. The bi-color (green/amber) System Status LED operates as follows: Table 70. System Status LED Color State Criticality Description Green Solid on System OK System booted and ready. Green 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 mirrored DIMM (memory mirroring). This indicates the user no longer has spare DIMMs indicating a redundancy lost condition. The corresponding DIMM LED should light up. Amber Blink Non-critical Non-fatal alarm - system is likely to fail: - Critical temperature threshold asserted - CATERR asserted - Critical voltage threshold asserted - VRD hot asserted - SMI Timeout asserted Amber Solid on Critical, recoverable non- Fatal alarm - system has failed or shut down - CPU Missing - Thermal Trip 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. - Power supply redundancy lost insufficient system power. This does not apply to non-redundant systems. Note: This state also occurs when AC power is first applied to the system. This indicates the BMC is booting. Off N/A Not ready - AC power off, if no degraded, non-critical, critical, or nonrecoverable conditions exist. - System is powered down or S5 states, if no degraded, non-critical, critical, or non-recoverable conditions exist. * When the server is powered down (transitions to the DC-off state or S5), the BMC is still on standby power and retains the sensor and front panel status LED state established before the power-down event. If the system status is normal when the system is powered down (the LED is in a solid green state), the system status LED is off. Revision 1.8 125 Intel order number E39529-013
